(Rev. 04/08) DDC-SVC-MAN-0040 0704 Copyright © 2008 DETROIT DIESEL CORPORATION MBE 900 ENGINE 2007 OPERATOR'S GUIDE INTRODUCTION This guide is intended for use by the operator of an MBE 900 diesel engine used in the following applications: □ On-Highway Vehicles □ Fire Truck or Crash/Rescue Vehicles Non-Genuine and Rebuilt Component Quality Alert Electronic engine controls have been instrumental in aiding engine manufacturers in meeting the stringent emission requirements of the U.S. Environmental Protection Agency (U.S. EPA) and the California Air Resources Board (CARB) and also in meeting the ever-increasing performance demands of the customer. Maintenance procedures must be followed in order to continue satisfactory performance and durability and to ensure coverage of the engine under the manufacturer's warranty. Many of these maintenance procedures also ensure that the engine continues to comply with applicable emissions standards. Proper maintenance procedures, using specific components engineered to comply with emissions regulations, may be performed by an authorized Detroit Diesel distributor or dealer, an independent outlet or the operator or owner. The owner is responsible All information subject to change without notice. (Rev. 04/08) for determining the suitability of components to maintain emissions compliance during the engine's useful emission life. Detroit Diesel cautions that the indiscriminate rebuilding of precision components, without the benefit of specifications, specialized equipment, and knowledge of the electronic operating system, will jeopardize performance or lead to more serious problems, and can take the engine outside of compliance with U.S. EPA or CARB emissions standards. There are other components in an engine, such as turbocharger, camshaft, piston, etc., which are specifically designed and manufactured to exacting standards for emissions compliance. It is important that these components, if replaced, modified or substituted, can be verified to ensure that the engine remains in compliance with emissions standards. The use of inadequately engineered, manufactured or tested components in repair or rebuild of the engine may be in violation of the federal Clean Air Act and applicable U.S. EPA or CARB regulations. DDC-SVC-MAN-0040 0704 Copyright © 2008 DETROIT DIESEL CORPORATION 1 INTRODUCTION Furthermore, modern engines exhibit operating parameters which require the use of proper fluids, such as fuel, coolant and lubricating oil, to maintain long engine life. The use of fluids that do not meet Detroit Diesel Corporation specifications may result in early wear out or engine failure. Personnel Requirements Work on the engine should be carried out only by skilled technicians who have been instructed in the specific skills necessary for the type of work being performed. Engine Conversions and Modifications The function and safety of the engine could be affected if unauthorized modifications are made. Detroit Diesel will not accept responsibility for any resulting damage. Tampering with the fuel injection system and engine electronics could also affect the engine's power output or exhaust emission levels. Compliance with the manufacturer's settings and with statutory environmental protection regulations cannot then be guaranteed. 2 All information subject to change without notice.

If the engine overheats, uses excessive fuel or lubricating All information subject to change without notice. (Rev. 04/08) Cooling System Checks 1. Make sure all drain cocks in the cooling system are installed (drain cocks are often removed for shipping) and are closed tightly. 2. Remove the radiator pressure control cap and fill with genuine Detroit Diesel POWER COOL® antifreeze or an equivalent quality ethylene glycol or propylene glycol-base antifreeze solution in the required concentration. In extremely hot environments, properly inhibited water may DDC-SVC-MAN-0040 0704 Copyright © 2008 DETROIT DIESEL CORPORATION 21 OPERATING INSTRUCTIONS FOR STARTING THE ENGINE be used in the summer. Keep the coolant level at the bottom of the filler neck to allow for expansion of the coolant. For more detailed recommendations, refer to How to Select Coolant in the HOW-TO SECTION of this guide. 3. Entrapped air must be purged after filling the cooling system. To do this, allow the engine to warm up with the pressure cap removed. With the transmission in neutral, increase engine speed above 1,000 rpm and add coolant to the radiator as required. 4. Check to make sure the front of the radiator and air-to-air charge cooler (if equipped) are unblocked and free of debris. Lubrication System Checks The lubricating oil film on the rotating parts and bearings of a new or newly overhauled engine, or one which has been in storage for six months or more, may be insufficient when the engine is started for the first time. NOTICE: Insufficient lubrication at startup can cause serious damage to engine components. To insure an immediate flow of oil to all bearing surfaces at initial 22 engine startup, the engine lubrication system should be charged with a commercially available pressure pre-lubricator. If this is impractical, rocker covers should be removed and clean lubricating oil should be poured over the rocker arms. The oil should be the same weight and viscosity as that used in the crankcase. After pre-lubricating, add additional oil to bring the level to the proper mark on the dipstick. For lubricant recommendation, refer to the How to Select Lubricating Oil section in this guide. Checking the Oil Level — Check the oil level as follows: 1. Remove the dipstick from the guide tube. Note the dipstick has a positive locking device such as a lever or twist-lock design that must be disengaged before pulling the dipstick out of the guide tube. 2. Use a shop rag to wipe off the end of the dipstick. 3. Wait 15 seconds to allow any crankcase pressure to dissipate through the guide tube and let the oil level settle in the oil pan. 4. Reinstall the dipstick and make sure it is fully inserted into the guide tube. 5. All information subject to change without notice. (Rev. 04/08) DDC-SVC-MAN-0040 0704 Copyright © 2008 DETROIT DIESEL CORPORATION MBE 900 ENGINE 2007 OPERATOR'S GUIDE Figure 11 Oil Dipstick Remove the dipstick and read the oil level see Figure 11. The figure shows a comparison between the bends on the dipstick and a crosshatch pattern on a conventional dipstick. Note the exact area noted on the bends. For example, the “maximum” oil level will be at the BOTTOM of that bend. For the “minimum” oil level, it is noted at the TOP of the bend. All information subject to change without notice. (Rev. 04/08) 6. Figure 12 Oil Fill Cap If the oil level is below the “minimum” bend, add oil to bring it up the “maximum” level. see Figure 11. Do NOT fill beyond the maximum fill level on the dipstick, since overfilling may result in high oil consumption and possible severe engine damage. If necessary, add additional oil DDC-SVC-MAN-0040 0704 Copyright © 2008 DETROIT DIESEL CORPORATION 23 OPERATING INSTRUCTIONS FOR STARTING THE ENGINE through oil fill cap located on the top of the engine. See Figure 12 PERSONAL INJURY To avoid injury from slipping and falling, immediately clean up any spilled liquids. Extended Storage — An engine in storage for an extended period of time (over winter, for example) may accumulate water in the oil pan through normal condensation of moisture (always present in the air) on the cold, internal surfaces of the engine. condensation and helps keep fuel cool, which is important to engine performance. Full tanks also reduce the chance for microbe (black slime) growth. For fuel recommendations, refer to the How to Select Diesel Fuel section in this guide. Make sure the fuel shutoff valve (if used) is open. NOTICE: Prolonged use of the starting motor and engine fuel pump to prime the fuel system can result in damage to the starter, fuel pump and injectors. This may cause erratic engine operation due to the amount of air in the lines and filters from the fuel supply tank to the cylinder head NOTICE: Failure to eliminate water-diluted lubricating oil may lead to serious engine damage at startup. Lube oil diluted by water cannot provide adequate bearing protection at engine startup. For this reason, Detroit Diesel recommends replacing the engine lubricating oil and filters after extended storage. Fuel System Checks Fill the tanks with the recommended fuel. Keeping tanks full reduces water 24 All information subject to change without notice. (Rev. 04/08) DDC-SVC-MAN-0040 0704 Copyright © 2008 DETROIT DIESEL CORPORATION MBE 900 ENGINE 2007 OPERATOR'S GUIDE NOTICE: Under no circumstances should a starting aid such as ether be used to run the engine until the fuel system is primed. Injector damage will result if this method is used. If an external starting aid is used, the heat generated by the external fuel source will cause the injector tips to be damaged when the fuel cools them. The injector plunger and bushing can be scored from running without lubrication. NOTICE: Engines equipped with starting devices dependent on compressed air or gas reservoirs should always be primed before initial startup. Otherwise, reserve pressure can be exhausted and injectors may be damaged from lack of lubrication and cooling. To insure prompt starting and even running, the fuel system must be primed if air has entered the fuel system. Priming can be performed by using the priming pump on the fuel filter or by connecting a manual or electric priming pump to the fuel filter housing. All information subject to change without notice. (Rev. 04/08) DDC-SVC-MAN-0040 0704 Copyright © 2008 DETROIT DIESEL CORPORATION 25 OPERATING INSTRUCTIONS FOR STARTING THE ENGINE Authorized Detroit Diesel service outlets are properly equipped and have the trained technicians to perform this service. Priming is not normally required if the filter elements are filled with clean fuel when installed and the lines are not drained of fuel. If priming is required refer to section Priming the Fuel System If the engine is equipped with a fuel/water separator, drain off any water that has accumulated. Water in fuel can seriously affect engine performance and may cause engine damage. Detroit Diesel recommends installation of a fuel/water separator wherever water contamination is a concern. Priming the Fuel System — Prime the fuel system as follows: 1. If equipped with a hand pump on the fuel filter or fuel/water separator, work the hand pump until resistance is felt. 2. Crank the engine for 30 seconds at a time, but no longer. Before cranking the engine again, wait at least two minutes. The engine should start within four 30-second attempts. Other Checks Make sure the transmission is filled to the proper level with the fluid recommended by the manufacturer. Do not overfill. Adding Fuel — Note the following when adding fuel: □ Add winter or summer grade fuel according to the season of the year. □ Work in the cleanest conditions possible. □ Prevent water from entering the fuel tank. For further information refer to “Diesel Fuels” in the HOW-TO SECTION of this guide. 26 All information subject to change without notice.

DDC-SVC-MAN-0040 0704 Copyright © 2008 DETROIT DIESEL CORPORATION 27 OPERATING INSTRUCTIONS FOR STARTING THE ENGINE Starting the Engine-For The First Time Before starting the engine the first time, perform the operations listed in the System Checks section. NOTICE: The turbocharger may be seriously damaged if the engine is cranked with the air shutdown in the closed position. To start an MBE 900 engine, make sure the transmission is in neutral and turn the ignition key on. ENGINE EXHAUST To avoid injury from inhaling engine exhaust, always operate the engine in a well-ventilated area. Engine exhaust is toxic. The engine may require the use of a cold weather starting aid if the ambient temperature is below 40°F (4°C). PERSONAL INJURY FLAMES, EXPLOSION AND TOXICITY To avoid injury from flames, explosion, and toxicants when using ether, the following precautions must be taken: □ Do not smoke when servicing ether system. □ Work in well ventilated area. □ Do not work near open flames, pilot flames (gas or oil heaters), or sparks. □ Do not weld or carry an open flame near the ether system if you smell ether or otherwise suspect a leak. 28 To avoid injury when working near or on an operating engine, remove loose items of clothing and jewelry. Tie back or contain long hair that could be caught in any moving part causing injury. You will notice that both the Amber Warning Lamp (AWL)/Check Engine and the Red Stop Lamp (RSL)/Stop Engine will come on. This is the result of the Detroit Diesel Electronic Control (DDEC®) computer diagnosing the system to ensure everything is functional, including the light bulbs for the warning lights. If everything is OK, both lights will go out in approximately five seconds. All information subject to change without notice. (Rev. 04/08) DDC-SVC-MAN-0040 0704 Copyright © 2008 DETROIT DIESEL CORPORATION MBE 900 ENGINE 2007 OPERATOR'S GUIDE Start the engine after the lights go out. If starting a vehicle, start the engine with foot off the foot pedal. NOTICE: If the warning lights stay on, or do not come on momentarily after turning on the ignition, contact the Detroit Diesel Customer Support Center at 313–592–5800. Operating the engine under these circumstances may result in engine damage. Electric Starter — Start an engine equipped with an electric starting motor as follows: NOTICE: To prevent serious starting motor damage, do not press the starter switch again after the engine has started. Important: At outside temperatures below –25°C (–13°F), a coolant preheater is recommended. 3. If the engine doesn't start after 30 seconds, stop. Try again after waiting two minutes. The engine should start within four 30-second attempts. NOTICE: Do not rev the engine if the oil pressure gauge indicates no oil pressure. To avoid engine damage, shut down the engine if no oil pressure appears within approximately ten seconds. Check to determine the cause of the problem. 4. Monitor the oil pressure gauge immediately after starting the engine. NOTE: Do not place the engine under full load until it reaches operating temperature. Running the Engine While the engine is operating, monitor the battery charge indicator light, the oil pressure and avoid excessive idling. 1. Chock the tires, place the transmission in neutral, and set the parking brake. 2. With foot OFF the foot pedal, turn on the ignition switch and start the engine All information subject to change without notice. (Rev. 04/08) DDC-SVC-MAN-0040 0704 Copyright © 2008 DETROIT DIESEL CORPORATION 29 OPERATING INSTRUCTIONS FOR STARTING THE ENGINE Oil Pressure Observe the oil pressure gage immediately after starting the engine. A good indicator that all moving parts are getting lubrication is when the oil pressure gage registers pressure (7 psi or 50 kPa at idle speed). If no pressure is indicated within 10 to 15 seconds, stop the engine and check the lubrication system. The pressure should not drop below 36 psi or 250 kPa at 1800 rpm, and normal operating pressure should be higher. If oil pressure does not fall within these guidelines, it should be checked with a manual gage. HOT OIL To avoid injury from hot oil, do not operate the engine with the rocker cover(s) removed. Warm-up Run the engine at part throttle for about five minutes to allow it to warm up before applying a load. Inspection While the engine is idling, inspect the transmission, check for fluid leaks, check the crankcase and turbocharger. 30 Transmission — While the engine is idling, check the automatic transmission (if equipped) for proper oil level and add oil as required. Fluid Leaks — Look for coolant, fuel or lubricating oil leaks. If any are found, shut down the engine immediately and have the leaks repaired after the engine has cooled. Crankcase — If the engine oil was replaced, stop the engine after normal operating temperature has been reached. Allow the oil to drain back into the crankcase for about twenty minutes, then check the oil level. If necessary, add oil to bring the level to the proper mark on the dipstick. Use only the heavy-duty oils recommended. Refer to the How to Select Lubricating Oil in this guide. Turbocharger — Make a visual inspection of the turbocharger for oil leaks, exhaust leaks, excessive noise or vibration. Stop the engine immediately if a leak or unusual noise or vibration is noted. Do not restart the engine until the cause of the concern has been investigated and corrected. Authorized Detroit Diesel service outlets are properly equipped to perform this service. All information subject to change without notice. (Rev. 04/08) DDC-SVC-MAN-0040 0704 Copyright © 2008 DETROIT DIESEL CORPORATION MBE 900 ENGINE 2007 OPERATOR'S GUIDE Avoid Unnecessary Idling Whenever possible, avoid unnecessary idling. During long engine idling periods with the transmission in neutral, the engine coolant temperature may fall below the normal operating range. The incomplete combustion of fuel in a cold engine will cause crankcase oil dilution, formation of lacquer or gummy deposits on the valves, pistons, and rings, and rapid accumulation of sludge in the engine. When prolonged idling is necessary, maintain at least 850 rpm spring/summer and 1200 rpm fall/winter. Stopping the Engine Stop an engine under normal operating conditions as follows: 1. Reduce engine speed to idle and put all shift levers in the neutral position. for four or five minutes. This allows the engine to cool and permits the turbocharger to slow down. After four or five minutes, shut down the engine. Emergency Jump Starting The DDEC VI system operates on 12 volts DC. If a DDEC VI engine with an electric starting motor requires emergency jump starting, do not exceed 16 volts DC. BATTERY EXPLOSION To avoid injury from battery explosion when jump starting the engine, do not attach the cable end to the negative terminal of the disabled battery. NOTICE: Stopping a turbocharged engine immediately after high-speed operation without allowing a sufficient cool-down period may cause damage to the turbocharger, as it will continue to turn without an oil supply to the bearings. 2. Allow the engine to run between idle and 1000 rpm with no load All information subject to change without notice. (Rev. 04/08) DDC-SVC-MAN-0040 0704 Copyright © 2008 DETROIT DIESEL CORPORATION 31 OPERATING INSTRUCTIONS FOR STARTING THE ENGINE NOTICE: Jump starting with voltages greater than those indicated or reversing battery polarity may damage the Motor Control Module (MCM). NOTICE: Failure to connect jumper cables in the proper sequence can result in alternator and/or equipment damage. Before attempting to jump start the engine, make sure the jumper cables are connected properly (positive to positive, negative to negative ground) and in the proper sequence (negative to negative ground last). Battery Explosion and Acid Burn To avoid injury from battery explosion or contact with battery acid, work in a well ventilated area, wear protective clothing, and avoid sparks or flames near the battery.

To decrease the idle speed, push the "Decel" switch until the idle is slow enough. NOTICE: Shutting Down the Engine If the engine has been running at full output or the coolant temperature has been high, allow the engine to idle for one to two minutes without load. Then turn off the ignition key switch. If any the following occur, shut down the engine immediately. □ The oil pressure swings back and forth or falls sharply. □ Engine power and rpm fall, even though the accelerator pedal remains steady. □ The exhaust pipe gives off heavy smoke. □ The coolant and/or oil temperature climb abnormally. □ Abnormal sounds suddenly occur in the engine or turbocharger. After hard operation, if the engine has been running at full output or the coolant temperature has been high, allow the engine to idle for one to two minutes without load. Shutting down the engine without idling may cause damage to the turbocharger. Turn off the ignition switch and shut down the engine. Emergency Running Mode The engine is equipped with the electronic engine control system, which monitors the engine as it is running. As soon as a fault is detected, it is evaluated and one of the following measures is initiated. NOTICE: To prevent possible serious engine damage, have any faults corrected without delay by an authorized dealer. □ In conjunction with any dash board or instrument panel display, the code for the electronic unit reporting the fault can be read immediately on the display. All information subject to change without notice. (Rev. 04/08) DDC-SVC-MAN-0040 0704 Copyright © 2008 DETROIT DIESEL CORPORATION 37 OPERATING INSTRUCTIONS FOR STARTING THE ENGINE □ Complete fault codes are transmitted and can be read using DDDL 7.0 or latest version. □ If the fault is serious enough to impair normal operation, the electronic engine system switches over to limp home mode. The limp home speed is dependent on MCM parameters and could be idle speed or 1000 rpm. This allows you to move the vehicle to a service location. For fault codes and their meanings, see the DDEC VI MBE 900 Troubleshooting Guide (6SE580). Stop Engine Override Option The Stop Engine Override Option is used for a momentary override. The MCM will record the number of times the override is activated after a fault occurs. Momentary Override – A Stop Engine Override (SEO) switch is used to override the shutdown sequence (see Figure 17). This override resets the 60 second (30 seconds for oil pressure) shutdown timer, restoring power to the level when the RSL (Stop Engine) was illuminated. The switch must be recycled after five seconds to obtain a subsequent override. 38 Figure 17 Typical SEO Switch and Warning Lamps NOTE: The operator has the responsibility to take action to avoid engine damage. Cold Weather Operation Special precautions must be taken during cold weather. To protect your engine, special cold weather handling is required for fuel, engine oil, coolant, and batteries. For detailed information on the grid heater and optional fuel filter heater, refer to the MBE 900 Service Manual (6SE9007). The engine will not require starting aids down to –15°C (5°F). Between –15°C (5°F) and –25°C (–13°F) a grid heater is required. Temperatures below –25°C (–13°F) will require a grid heater, block heater, and oil pan heater. An optional fuel heater is available.

(Rev. 04/08) DDC-SVC-MAN-0040 0704 Copyright © 2008 DETROIT DIESEL CORPORATION 39 DDEC VI SYSTEM DDEC VI SYSTEM The engine is equipped with a fully electronic control system, which regulates the fuel injection quantity and timing using solenoid valves, allowing extremely low-emission operation. Besides the engine and its related sensors, the system is composed of the following: Motor Control Module The MCM (see Figure 18) is located on the left-hand side of the engine. The MCM processes the data received from the CPC, for example the position of the accelerator pedal, engine brake, etc. □ The Motor Control Module (MCM) □ The Common Powertrain Controller (CPC) located under the right-hand dash panel The two control units are connected by a proprietary datalink through which all necessary data and information can be exchanged. The CPC then broadcasts all information on the J1587 and J1939 datalinks, where it can be read by the diagnostic tool. The engine control system monitors both the engine and the datalink. When a malfunction or other problem is detected, the system selects an appropriate response; for example, the emergency running mode may be activated. Figure 18 MCM These data are evaluated together with the data from the sensors on the engine, such as coolant and fuel temperature and oil and charge pressure. The Accelerator Pedal Assembly (AP) eliminates the need for any throttle linkage. 40 All information subject to change without notice. (Rev. 04/08) DDC-SVC-MAN-0040 0704 Copyright © 2008 DETROIT DIESEL CORPORATION MBE 900 ENGINE 2007 OPERATOR'S GUIDE The data is then compared to the characteristic maps or lines stored in the MCM. From these data, quantity and timing of injection are calculated and the unit pumps are actuated accordingly through the solenoid valves. NOTE: To obtain a replacement MCM, all the data given on the MCM label are required. The MCM data label has the 10 digit engine serial number. Common Powertrain Controller The CPC communicates with any other MCM unit installed on the vehicle over the J1939 data link. See Figure 19. Data for specific applications is stored in the CPC. These include idle speed, maximum running speed, and speed limitation. Figure 19 CPC The CPC receives data from the following sources: □ The operator (accelerator pedal position, engine brake switch) □ Other electronic control units (for example, the anti-lock brake system) □ The MCM (oil pressure and coolant temperature) From these data, instructions are computed for controlling the engine and transmitted to the CPC via the proprietary datalink. The CPC controls various systems, for example, communications with the datalink, the engine brake, and the constant-throttle valves. All information subject to change without notice. (Rev. 04/08) DDC-SVC-MAN-0040 0704 Copyright © 2008 DETROIT DIESEL CORPORATION 41 DDEC VI SYSTEM DDEC Features DDEC offers a variety of features and options designed to warn the operator of an engine malfunction. Options can range from warning panel lights to automatic reduction in engine power followed by automatic engine shutdown. DDEC has the ability to perform diagnostics for self-checks and continuous monitoring of other system components. Depending on the application, DDEC can monitor oil temperature, coolant temperature, oil pressure, fuel pressure, coolant level and remote sensors (if used). DDEC connects to the AWL (Check Engine) and the RSL (Stop Engine) to provide a visual warning of a system malfunction. Cruise Control Cruise Control is available with any DDEC engine. Cruise Control will operate in either Engine or Vehicle Speed Mode and maintain a targeted speed (MPH or RPM) by increasing or decreasing fueling. The targeted speed can be selected and adjusted with dash-mounted switches. See Figure 20. 42 Figure 20 Typical Cruise Control Switches Cruise Control may also be programmed to permit fast idle using the Cruise Control switches. With the engine at normal idle, transmission in neutral and service brakes on, depress the SPD CNTL Switch, and use the RSM/ACC Switch.. The engine rpm should increase to a pre-defined speed. The engine rpm can be raised or lowered from this point using the SET/CST and RSM/ACC switches. Cruise Control will maintain the set speed under normal road and load conditions. All information subject to change without notice. (Rev. 04/08) DDC-SVC-MAN-0040 0704 Copyright © 2008 DETROIT DIESEL CORPORATION MBE 900 ENGINE 2007 OPERATOR'S GUIDE LOSS OF VEHICLE CONTROL To avoid injury from the loss of vehicle control, do not use cruise control under these conditions: □ When it is not possible to keep the vehicle at a constant speed (on winding roads, in heavy traffic, in traffic that varies in speed, etc.). □ On slippery roads (wet pavement, ice-or snow-covered roads, loose gravel, etc.). NOTICE: When descending a hill with Cruise Control OFF, do not allow the engine to exceed 2500 rpm under any conditions. Failure to observe this precaution can result in overspeeding and serious engine damage. It cannot limit vehicle speeds on down grades if available engine braking effort is exceeded, nor can it maintain speed on upgrades if power requirements exceed engine power capability. set vehicle speed. The vehicle speed must be above Min. Cruise Set Speed and below Max. Cruise Set Speed. It is recommended that Max Cruise Set Speed be set to the default to allow proper operation of other features such as Fuel Economy Incentive and PasSmart. The Vehicle Speed Limit should be used to limit vehicle throttle speed. When the SPD CNTL is in the ON position, Cruise Control is engaged by momentarily contacting the SET/CST Switch. As a check after each engine start, DDEC looks for a one time activation of the clutch (if equipped) and service brake before DDEC allows Cruise Control to be enabled. The MCM must also recognize that the Cruise Enable Switch has changed. If the Cruise Enable Switch is off, it needs to be turned on. If the Cruise Enable Switch is on, it must be turned off then on for cruise to operate. Holding the switch in the SET/CST position allows the vehicle to slow to a lower speed. Toggling the switch will result in a one mile-per-hour (1.6 kph) decrease in vehicle speed. If Cruise Control has been disabled, toggling the RSM/ACC Switch restores the vehicle to the previously set cruise speed. Engine speed and power are varied under Cruise Control to maintain the All information subject to change without notice. (Rev. 04/08) DDC-SVC-MAN-0040 0704 Copyright © 2008 DETROIT DIESEL CORPORATION 43 DDEC VI SYSTEM Cruise Control can be overridden at any time with the throttle pedal if the vehicle is operating at less than the programmed Max Road Speed. Additionally, using either the brake or the clutch will disable Cruise Control. Data Recording Capability The DDEC VI contains the ability to extract detailed data on the engine’s use and performance using DDEC Reports software. This data, known as DDEC Data, is stored in the CPC and contains information on engine performance (such as fuel economy, idle time, time in top gear) and critical incidents (such as detailed diagnostic data records and hard braking events). DDEC Data can be downloaded using DDEC Reports software to produce reports. DDEC Reports software is part of the Detroit Diesel Diagnostic Link® 7.0 (DDDL 7.0) software package. DDDL 7.0 requires at least a Pentium II computer with at least 256 MB of RAM. Engine Brakes Engine brakes are enabled by a dash-mounted On/Off switch with a separate intensity switch to select low, medium or high braking power. 44 LOSS OF VEHICLE CONTROL To avoid injury from loss of vehicle control, do not activate the Engine Brake system under the following conditions: □ On wet or slippery pavement, unless the vehicle is equipped with ABS (anti-lock braking system) and you have had prior experience driving under these conditions. □ When driving without a trailer (bobtailing) or pulling an empty trailer. □ If the tractor drive wheels begin to lock or there is fishtail motion after the Engine Brake is activated, deactivate the brake system immediately if this occurs. The engine brakes will only operate when the Accelerator Pedal is fully released. Disengaging the clutch will prevent the engine brakes from operating. All information subject to change without notice. (Rev. 04/08) DDC-SVC-MAN-0040 0704 Copyright © 2008 DETROIT DIESEL CORPORATION MBE 900 ENGINE 2007 OPERATOR'S GUIDE Engine brakes will supply braking power even when in Cruise Control. The MCM will control the amount of engine braking with respect to the Cruise Control set speed. The maximum amount of braking (low, medium, high) is selected with the dash switches. Engine Protection The DDEC engine protection system monitors all engine sensors and electronic components, and recognizes system malfunctions. If a critical fault is detected, the AWL (Check Engine) and RSL (Stop Engine) illuminate. The malfunction codes are logged into the MCM's memory. The standard parameters which are monitored for engine protection are: low coolant level, high coolant temperature, low oil pressure, and high oil temperature. This system features a 30-second, stepped-power shutdown sequence or an immediate speed reduction without shutdown in the event a major engine malfunction occurs, such as low oil pressure, high oil or coolant temperature, or low coolant level. All information subject to change without notice. (Rev. 04/08) PERSONAL INJURY To avoid injury from engine shutdown in an unsafe situation, ensure the operator knows how to override the stop engine condition on a DDEC-equipped unit. NOTICE: Engines equipped with the power-down/shutdown option have a system override button or switch to allow engine operation for a short period of time. Using the override button so the engine does not shutdown in 30 seconds but operates for an extended period may result in engine damage. California Engine Idle Limiting In order to meet the California Engine Idle Limiting Standard, an engine idle shutdown feature has been built into the DDEC VI Engine Control Strategy. When the California Engine Idle Limiting feature is enabled, the engine will generally shut down after five minutes of continuous idling when the transmission is in neutral or park and the parking brake is set or after fifteen minutes when the transmission is in neutral or park and DDC-SVC-MAN-0040 0704 Copyright © 2008 DETROIT DIESEL CORPORATION 45 DDEC VI SYSTEM the parking brake is not set. Activating or momentarily changing the position of the service brake pedal, the clutch pedal, Stop Engine Override, the accelerator pedal, or park brake status during the final 30 seconds before a shutdown would otherwise occur will prevent the engine from shutting down and will reset the shutdown timer. After an automatic shutdown, the engine may be restarted and operated normally. The automatic shutdown feature is generally disabled on engines certified by the US EPA for use outside California but is required to be enabled for all California certified engines with the exception of engines used in specific vehicle types which the state of California has determined to be exempt from the idle shutdown requirement. These include buses, school buses, recreational vehicles, medium duty vehicles, military tactical vehicles, and authorized emergency vehicles as they are defined by the state of California. Owners of these vehicle types that wish to have the shutdown feature disabled should consult with California authorities to determine if their vehicles qualify for the exemption. eliminating excessive idling and allowing a turbocharger cool-down period. To activate the shutdown, the transmission must be in neutral with the vehicle parking brakes set and the engine in idle or fast-idle mode. DDEC VI Operation NOTE: This engine is equipped with DDEC software. This software generally assures optimal engine performance. The installation of software upgrades may cause minor changes in features and engine performance. Since the DDEC system is electronic, a battery is required to operate the computer. The system operates at 12 volts DC. However, in the event of a power supply malfunction, the system will continue to operate at reduced voltage. When this occurs, the AWL (Check Engine) will come on. See Figure 21. Idle Shutdown Timer This feature is an optional 1 – 100 minute idle shutdown system. Its purpose is to conserve fuel by 46 Figure 21 Warning Lamps and SEO Switch All information subject to change without notice. (Rev. 04/08) DDC-SVC-MAN-0040 0704 Copyright © 2008 DETROIT DIESEL CORPORATION MBE 900 ENGINE 2007 OPERATOR'S GUIDE The engine will only operate at reduced rpm until the battery voltage reaches a point where the MCM will no longer function and the engine shuts down. Should the AWL (Check Engine) come on for any reason, the vehicle can still be operated and the driver can proceed to the required destination. This condition should be reported to an authorized Detroit Diesel distributor or dealer. Stop Engine Override Switch This feature allows the operator to override the automatic stop engine sequence. This is done by pressing the Stop Engine Override Switch every 15 to 20 seconds to prevent engine shutdown from occurring. NOTE: The Stop Engine Override Switch and the Diagnostic Request Switch are the same. NOTICE: When the RSL (Stop Engine) comes on, the computer has detected a major malfunction in the engine that requires immediate attention. It is the operator's responsibility to shut down the engine to avoid serious damage. The engine can be configured to give a warning only, to ramp down (reduce power) or to shut down. Ramp down will reduce engine rpm to a pre-determined speed, but will not shut down the engine. With the 30-second shutdown option, the engine will begin a 30-second, stepped power-down sequence until it shuts down completely. NOTE: Holding down the Stop Engine Override Switch will not prevent the engine shutdown sequence. You must continue to reset the automatic shutdown system by pressing the Stop Engine Override Switch at intervals of approximately 15 to 20 seconds. It takes 30 seconds from the time the automatic shutdown sequence begins until engine shutdown. Therefore, the operator must press the override switch just prior to engine shutdown and continue to do so until the vehicle can be brought to a stop in a safe location. A “Stop Engine Override” can be procured in case the vehicle is to operate in a critical location. All information subject to change without notice. (Rev. 04/08) DDC-SVC-MAN-0040 0704 Copyright © 2008 DETROIT DIESEL CORPORATION 47 DDEC VI SYSTEM Immediate Speed Reduction The immediate speed reduction option will bring engine rpm back to a predetermined speed, but will not shut down the engine. The engine should not be restarted after it has been shut down by the engine protection system, unless the problem has been located and corrected. Red Stop Lamp The conditions that will cause the RSL (Stop Engine) to come on are: □ High coolant temperature □ Loss of coolant □ High oil temperature □ Low oil pressure □ Auxiliary shutdown Whenever the AWL (Check Engine) or the RSL (Stop Engine) come on, the DDEC computer will determine where the problem is and will then store this information in its memory. If the malfunction is intermittent, the lights will come on and go off as the computer senses the changing engine condition. Diagnostic Tool The diagnostic tool for DDEC VI is DDDL 7.0. which requires at least a 48 Pentium II computer with at least 256 MB of RAM. Once the malfunction has been corrected, the DDEC system will return the engine to normal operation. The temperature of air in the intake system is increased with the addition of an EGR. DDEC is programmed to reduce fueling (power) for a short time to reduce air and coolant temperatures when necessary. DDEC will store an information code that this event occurred, but no corrective action is required as this action is designed to maintain operation without a noticeable affect on vehicle performance. Flashing Malfunction Codes — All malfunction codes are four digits. The malfunction code recorded in the computer memory will remain until it is erased by a technician. The flashing malfunction code can also be obtained by the operator. To support flashing codes, a Stop Engine Override/Diagnostic Request Switch must be configured and the AWL (Check Engine) and RSL (Stop Engine) must be hard-wired. The CPC cannot flash these lamps if they are not hard-wired. The flashing code feature may be activated by satisfying one of the following conditions: All information subject to change without notice. (Rev. 04/08) DDC-SVC-MAN-0040 0704 Copyright © 2008 DETROIT DIESEL CORPORATION MBE 900 ENGINE 2007 OPERATOR'S GUIDE □ Engine speed is <100 rpm and the SEO switch is put in the ON position. □ Vehicle speed is <3 mph and Park Brake is activated and the SEO switch is put in the ON position. □ Idle Governor is activated and the SEO switch is put in the ON position. The flashing code feature is deactivated to the OFF position or the listed conditions are no longer satisfied.See Figure 22 . Figure 22 RSL (Stop Engine) Flashing Code Example Only one light will be flashing codes at any time. All codes will be flashed twice. The inter-digit pause is 1.5 seconds. The pause between codes is 3.5 seconds. The same 3.5 second pause occurs as the switch is made from RSL (Stop Engine) to AWL (Check Engine). When code flashing is initiated, the active codes will be flashed on the RSL (Stop Engine). Then the inactive codes will be flashed on the AWL (Check Engine). When all the inactive codes have been flashed, the process of flashing all the active codes All information subject to change without notice. (Rev. 04/08) followed by all the inactive codes will repeat until the conditions for code flashing are no longer satisfied. If there are no active or inactive faults the number 3 is flashed once followed by an inter-code gap of 3 seconds. To Read Codes: Press and hold the SEO/Diagnostic Request Switch. Active codes will be flashed on the RSL (Stop Engine) first, followed by inactive codes being flashed on the AWL (Check Engine). DDC-SVC-MAN-0040 0704 Copyright © 2008 DETROIT DIESEL CORPORATION 49 DDEC VI SYSTEM The codes will continue to flash and repeat as long as the Diagnostic Request Switch is held in the ON position. Both CPC and MCM faults are included. Active Codes – The active codes will be flashed on the RSL (Stop Engine) in the order of most recent to least recent occurrence based on engine hours. Inactive Codes – The inactive codes will be flashed on the AWL (Check Engine) in the order of most recent to least recent occurrence based on engine hours. 50 All information subject to change without notice. (Rev. 04/08) DDC-SVC-MAN-0040 0704 Copyright © 2008 DETROIT DIESEL CORPORATION MBE 900 ENGINE 2007 OPERATOR'S GUIDE DDEC VI ENGINE DRIVING TIPS Driving with an electronically controlled engine feels different from driving with a mechanically governed engine. Accelerating the Vehicle Engine response versus pedal movement may feel different from the mechanical-governed engine you were driving. The Accelerator Pedal (AP) was designed to communicate “percentage” foot pedal travel to the engine's Motor Control Module (MCM). The engine will respond accordingly to the driver's demand. Cruise Control For added driver convenience and comfort, DDEC VI also features a Cruise Control option that works just like the system in your car. It can be operated in any gear above 1000 rpm or road speed faster than 32 kph (20 mph), up to the rated engine speed. And it can be programmed to hold your road speed at or below the maximum vehicle speed. The switch to energize Cruise Control is usually mounted on the instrument panel. See Figure 23. Another throttle or governor characteristic you may need time to get used to is the DDEC Limiting Speed Governor. This allows the driver to command total engine response between idle and rated speed, such as accelerating at half throttle – an advantage when driving under slippery conditions. If you require wide-open throttle engine response, either accelerating or just plain pulling hard, the throttle AP will have to be held to the floor. To obtain 100% fueling at any speed, the AP will have to be maintained at the fully pressed position. All information subject to change without notice. (Rev. 04/08) Figure 23 Typical Cruise Control Switches DDC-SVC-MAN-0040 0704 Copyright © 2008 DETROIT DIESEL CORPORATION 51 DDEC VI ENGINE DRIVING TIPS speed in one mile-per-hour (1.6 kilometer-per-hour) increments, press the RSM/ACL Switch. To reduce road speed, press and hold the SET/CST Switch until the lower speed is reached. Turn the switch ON to energize the system. Remember as a check after each engine start, the MCM looks for a one time activation of the clutch (if equipped) and service brake before the MCM allows Cruise Control to be enabled. Cruise Control is deactivated by slightly pressing the service brakes, clutch pedal, or trailer brake. The On/Off Switch will also deactivate Cruise Control. DDEC VI must also see or recognize that the Cruise Enable Switch has changed. If the Cruise Enable Switch is OFF it needs to be turned ON. If the Cruise Enable Switch is left in the ON position at key OFF, the switch must be cycled OFF then ON for DDEC VI to see a status change to allow Cruise Control activation. The status of DDEC VI inputs to activate Cruise Control at key ON is listed in Table 2 below. Cruise Control will maintain vehicle speed even on up grades, unless power requirements demand a downshift. And, of course, Cruise Control does not limit your speed on down grades. Most likely, Cruise Control will feel stronger than driving with the foot pedal because of the instantaneous and wide-open throttle response. That's why Cruise Control use is not suggested during slippery driving conditions. Once Cruise Control is enabled and you reach your road speed, press the Set Switch to activate Cruise Control. The cruise light will come on.

(Rev. 04/08) DDC-SVC-MAN-0040 0704 Copyright © 2008 DETROIT DIESEL CORPORATION MBE 900 ENGINE 2007 OPERATOR'S GUIDE Use Cruise Control after down shifting on a hill to pull the hill. Hitting the RSM/ACL Switch (not the Set Switch) will keep the truck accelerating in the lower gears up to the rated engine speed. Cruise Control will disengage below 1000 rpm or 32 kph (20 mph) road speed. When using Cruise Control, if you want to pull the engine below 1000 rpm, remember to hold the throttle pedal to the floor to keep the engine pulling at wide-open throttle. Realistically, the engine will pull to about 1050 rpm. Remember: The electronic data programmed into the DDEC VI system will not allow you to hurt or overfuel the engine at low or “lug” engine speeds. There is enough oil pressure to withstand hard pulls at low engine speeds. Engine Brakes and Cruise Control If your engine is equipped with both Cruise Control and engine brake retarders, the engine retarders can operate automatically while you are in Cruise Control. If the Cruise Control/Engine Brake function is turned ON in the MCM programming, the engine retarders will come on “low” when your set road speed increases a few miles-per-hour (kilometers per hour) above your All information subject to change without notice. (Rev. 04/08) cruise set speed. If your speed continues to increase, the MCM will increase the engine retarders' braking power progressively. When the vehicle returns to the set cruise speed, the engine retarders will turn off until you need them. For safety reasons, don't use Cruise Control when it is not possible to keep the vehicle at constant speed due to: □ Winding roads □ Heavy traffic □ Slippery pavement □ Descending grades that call for engine brake assistance. For an explanation of the engine brake retarder system and recommendations for proper operation, refer to ENGINE BRAKE SYSTEM. Shifting Depending on your transmission model, the gear split may vary from 500 to 300 rpm. The electronic governor provides almost no overrun capability; and, if the transmission is downshifted too early, you will experience a temporary loss of pulling power until the engine speed falls below rated speed. DDC-SVC-MAN-0040 0704 Copyright © 2008 DETROIT DIESEL CORPORATION 53 DDEC VI ENGINE DRIVING TIPS In general, when using a 7 or 9-speed transmission, you should always downshift between 1250 and 1300 rpm. This is true even on steep grades with heavy loads. When using an 18-, 15- or 13-speed transmission, you will need to downshift at an rpm that allows “less than rated” rpm before throttle application in the next gear down. You may want to limit engine speed to 1900 rpm in all gears. Low rpm operation should feel greatly enhanced due to the characteristics of the variable nozzle turbocharger. Engine response should be almost instantaneous below peak torque engine speeds. This should encourage progressive shifting especially during slow vehicle speed operation. Idling The common belief that idling a diesel engine causes no engine damage is wrong. Idling produces sulfuric acid, which breaks down the oil and eats into bearings, rings, valve stems and engine surfaces. If you must idle the engine for cab heat or cooling, the high idle function of the Cruise Control switches should be used. An idle speed of 1100 rpm should be enough to provide cab heat in above 0° C (32° F) ambients. One difference you may notice with the EGR equipped engine is under hood noise. The gear train has been redesigned for quieter operation, and the EGR gas flow may be noticeable to the tuned attentive ear. The turbocharger operates at higher boost pressure forcing EGR gas flow through the EGR plumbing. In some situations the driver may believe he/she has experienced a charge air cooler system leak. Even connecting trailer light and air hoses, the driver may hear a different tone (exhaust and under hood with the engine idling.) If equipped with a turbo boost gage, the driver may occasionally note intake manifold pressure exceeds 35 psi. 54 All information subject to change without notice. (Rev. 04/08) DDC-SVC-MAN-0040 0704 Copyright © 2008 DETROIT DIESEL CORPORATION MBE 900 ENGINE 2007 OPERATOR'S GUIDE ENGINE BRAKE SYSTEM Certain MBE 900 vehicle engines are equipped with engine brakes, commonly referred to as retarders. Before operating the vehicle, you must familiarize yourself with the retarder system to obtain optimum benefit from it. Engine brake control systems may vary slightly, depending on the engine brake configuration and cab design. However, basic operator controls are similar for all models. Exhaust Brake/Constant-Throttle Valves, Optional To increase braking performance, the engine can be equipped with an exhaust brake on the turbocharger in conjunction with constant-throttle valves in the cylinder head. See Figure 24. The two systems operate independently of each other and in combination. Exhaust back pressure is used by the exhaust brake to increase braking performance. The constant-throttle valves use the air that escapes through them on the compression stroke to provide braking force. The constant-throttles valves are small valves which are built into the cylinder head and positioned opposite the exhaust valve. When open, a link is created between the combustion chamber and the exhaust port. When the engine brake is switched on, the constant-throttle valves are put under pressure, which in turn opens the valves. The constant-throttle valves are activated by engine oil pressure. The engine brake is activated by the CPC and can be activated only at engine speeds up to 2600 rpm. Below 900 rpm, the engine brake is always turned off to prevent the engine from stalling. Also, the engine brake is automatically turned off when the accelerator pedal is pressed. Figure 24 Constant — Throttle Activation All information subject to change without notice. (Rev. 04/08) NOTE: When in emergency running mode (constant rpm), the engine brake can DDC-SVC-MAN-0040 0704 Copyright © 2008 DETROIT DIESEL CORPORATION 55 ENGINE BRAKE SYSTEM be activated only when the engine is in overrun. When constant rpm has been attained, the engine brake is automatically turned off. Anti-Lock Braking Systems Vehicles equipped with Anti-lock Braking Systems (ABS) have the ability to turn the engine brake retarder OFF if a wheel-slip condition is detected. The engine brake will automatically turn itself ON once the wheel slip is no longer detected. The DDEC system will deactivate the engine brake system when the engine speed falls below 1000 rpm or when the vehicle slows down to a pre-set speed, depending on MCM programming. This prevents stalling the engine. Engine brakes can also be used with vehicle Cruise Control TURNED ON. Driving on Flat, Dry Pavement Use the following guidelines when driving on flat, dry pavement: 1. If driving on flat, dry, open stretches with a light load and greater slowing power is not required, place the progressive braking switch in the LOW position. 56 2. If you find you are still using the service brakes, move the switch to a higher position until you do not need to use the service brakes to slow the vehicle down. 3. If you are carrying a heavier load and road traction is good, move the progressive braking switch to the “High” position. 4. Check your progressive braking switch often for proper position, since road conditions can change quickly. Never skip a step when operating the progressive braking switch. Always go from OFF to LOW, and then to a higher position. Descending a Long, Steep Grade An explanation of “control speed” may be helpful in understanding how to use the engine brake system while descending a grade. Control Speed is the constant speed at which the forces pushing the vehicle forward on a grade are equal to the forces holding it back, without using the vehicle service brakes. In other words, this is the speed the vehicle will maintain without using the service brakes or fueling. All information subject to change without notice. (Rev. 04/08) DDC-SVC-MAN-0040 0704 Copyright © 2008 DETROIT DIESEL CORPORATION MBE 900 ENGINE 2007 OPERATOR'S GUIDE BRAKE FADE To avoid injury, do not over apply the vehicle service brakes when descending a long, steep grade. Excessive use of the vehicle brakes will cause them to heat up, reducing their stopping ability. This condition, referred to as “brake fade”, may result in loss of braking, which could lead to personal injury or vehicle/property damage or both. Use the following guidelines when descending a long, steep grade: 1. Before beginning the descent, determine if your engine brake system is operating properly by lifting your foot briefly off the throttle. You should feel the system activate. 2. Ensure the progressive braking switch is in the appropriate power position. PERSONAL INJURY Failure to keep the vehicle within safe control speed limits while descending a grade may result in loss of vehicle control, which could cause personal injury. NOTICE: Failure to keep the vehicle within safe control speed limits while descending a grade may result in vehicle or property damage or both. 3. Do not exceed the safe control speed of your vehicle. Example: You could descend a 6% grade, under control only at 16 kph (10 mph) without an engine brake, but at 40 kph (25 mph) with an engine brake. You could not descend that same hill at 80 kph (50 mph) and still expect to remain under control. Get to know how much slowing power your engine brake can provide. So get to know your engine brake system before climbing hills and do not exceed a safe control speed. 4.

Always go from OFF to LOW and then to a higher position when on slippery roads. Driving on Wet or Slippery Pavement Do not attempt to use the engine brake system on wet or slippery roads until you have some experience with it on dry pavement. LOSS OF VEHICLE CONTROL To avoid injury from loss of vehicle control, do not activate the Engine Brake system under the following conditions: □ On wet or slippery pavement, unless the vehicle is equipped with ABS (anti-lock braking system) and you have had prior experience driving under these conditions. □ When driving without a trailer (bobtailing) or pulling an empty trailer. □ If the tractor drive wheels begin to lock or there is fishtail motion after the Engine Brake is activated, deactivate the brake system immediately if this occurs. 58 NOTE: On single trailers or combinations, a light air application of the trailer brakes may be desirable to help keep the trailer stretched out. Follow the manufacturer's recommended operating procedure when using your trailer brakes. On wet or slippery pavement, start with the master switch in the OFF position and use the gear you would normally use under these conditions. If the vehicle is maintaining traction, place the selective braking switch in the LOW position and turn ON the engine brake system. If the drive wheels are maintaining traction and you desire greater slowing power, move the braking switch to the next highest position. However, if the tractor drive wheels begin to lock or there is a fishtail motion, turn the engine brake system OFF immediately and do not activate it until road conditions improve. Check your progressive braking switch often for proper position, since road conditions can change quickly. Never skip a step when operating the progressive braking system.

(Rev. 04/08) DDC-SVC-MAN-0040 0704 Copyright © 2008 DETROIT DIESEL CORPORATION MBE 900 ENGINE 2007 OPERATOR'S GUIDE ENGINE SYSTEMS The engine systems are the following: Fuel System The fuel system consists of Motor Control Module (MCM), fuel injectors, Electronic Unit Pumps (EUP), fuel pump, a fuel heat exchanger, a multi-functional fuel filter containing primary and secondary filtration with a fuel priming valve and a water separator, and the necessary connecting fuel lines. Air System The outside air drawn into the engine passes through the air filter and is pulled into the turbocharger and compressed. It then moves to the air-to-air charge cooler (heat exchanger) and is cooled. Next it flows to the intake manifold and into the cylinders, where it mixes with atomized fuel from the injectors. The gear-type fuel pump is bolted to the front of the cylinder block. The pump is driven from the forward end of the camshaft. For optimum protection of the engine from dust and other airborne contaminants, service the dry type air cleaners used when the maximum allowable air restriction has been reached, or annually, whichever occurs first. Lubrication System Cooling System The lubricating oil system consists of an oil pump, pressure regulator, pressure relief valve, oil filters, oil filter adaptor, oil cooler, oil level dipstick, oil pan and ventilation. The water pump is mounted on the front of the cylinder block and is belt driven by the crankshaft pulley. This system has a centrifugal type water pump to circulate coolant within the engine. Two full-blocking type thermostats located in a housing attached to the front of the cylinder block. There is a force-feed lubricating oil circuit supplied by a rotary oil pump. This pump is in the front cover and is drive by a gear on the front of the crankshaft. The oil cooler is located on the right side front of the cylinder block near the oil filter. All information subject to change without notice. (Rev. 04/08) DDC-SVC-MAN-0040 0704 Copyright © 2008 DETROIT DIESEL CORPORATION 59 ENGINE SYSTEMS Electrical System The electrical system consists of a starting motor, starting switch, battery-charging alternator, storage batteries, and the necessary wiring. Exhaust System Exhaust gases exit the cylinders through exhaust ports and the exhaust manifold. These exhaust gases expand through the exhaust turbine and drive the turbocharger compressor impeller. The gases are then released through the exhaust pipes and the aftertreatment device to the atmosphere. Exhaust Gas Recirculation System The purpose of the Exhaust Gas Recirculation System (EGR) is to reduce engine exhaust gas emissions in accordance with EPA regulations. The MBE 900 engines for on-highway EPA 2007 regulation applications use a cooled EGR system along with an Aftertreatment System to meet the emission standards. On the 260 – 350 horsepower engines, the EGR is fed by all six cylinders. The low horsepower engines use an asymmetric turbocharger with two entries, and the EGR is fed from the first three cylinders, taken from a small entry. The exhaust with a maximum exhaust gas temperature of 730°C (1346°F) is cooled to a maximum of 150°C (302°F) in the EGR cooler. The cooled exhaust gases then pass through the EGR valve and added to the mixer housing. The addition of cooled exhaust gases back into the combustion airflow reduces the peak cylinder combustion temperature. Less oxides of nitrogen (NOx) are produced at lower combustion temperatures. The EGR system has been optimized to dramatically cut NOx formation by routing a measured amount of exhaust flow to the cylinders to lower combustion temperatures. Lower temperatures result in lower NOx levels without the negative effects of retarding engine timing. The EGR valve has been moved to the top of the engine for improved serviceability. The EGR system consists of an EGR cooler, EGR valve, and an EGR mixer. 60 All information subject to change without notice. (Rev. 04/08) DDC-SVC-MAN-0040 0704 Copyright © 2008 DETROIT DIESEL CORPORATION MBE 900 ENGINE 2007 OPERATOR'S GUIDE AFTERTREATMENT SYSTEM In order to meet current emissions regulations, the traditional muffler has been replaced by a new Aftertreatment Device (ATD). This device consists of a Diesel Oxidation Catalyst (DOC) and a Diesel Particulate Filter (DPF). Together these two components burn off collected particulate matter in a process called “regeneration.” The Figure 25 key to successful regeneration is high exhaust temperature for an extended period of time. Without adequate temperatures for regeneration, the filter will continue to trap particulates and eventually plug. In order to avoid plugging, Detroit Diesel has designed an actively regenerated Aftertreatment System (ATS). See Figure 25. Aftertreatment System Schematic All information subject to change without notice. (Rev. 04/08) DDC-SVC-MAN-0040 0704 Copyright © 2008 DETROIT DIESEL CORPORATION 61 AFTERTREATMENT SYSTEM Operating Requirements Oxidation of the particulate matter is the key to filter performance. This requires that the catalyzing agent (platinum coated passages) are providing optimum enhancement to the oxidation process. The following requirements must be met, otherwise ATD warranty may be compromised: NOTICE: Do not use kerosene or fuel blended with used lube oil. □ Use Ultra-Low Sulfur Diesel (ULSD) fuel with (15 ppm sulfur content maximum), based on ASTM D2622 test procedure □ Lube oil must have a sulfated ash level less than 1.0 wt %; currently referred to as CJ-4 oil. NOTICE: Engine) or RSL (Stop Engine) are indications of a system problem. Should this occur, refer to the Aftertreatment System Technician's Guide (7SE63), or contact the Detroit Diesel Customer Support Center at 313–592–5800. Illumination of the Diesel Particulate Filter (DPF) lamp indicates that a parked regeneration is required. There is a need to periodically remove accumulated ash, derived from engine lube oil, from the filter. This ash does not oxidize in the filter during the regeneration process and must be removed through a cleaning procedure. All Detroit Diesel ATD equipped engines will illuminate a dashboard warning lamp indicating the need for ash cleaning. For information on this cleaning procedure, refer to the Aftertreatment System Technician's Guide (7SE63), or contact the Detroit Diesel Customer Support Center at 313–592–5800. Not following the operating requirements may result in damage to the ATD or accelerated ash plugging of the diesel particulate filter.

(Rev. 04/08) DDC-SVC-MAN-0040 0704 Copyright © 2008 DETROIT DIESEL CORPORATION MBE 900 ENGINE 2007 OPERATOR'S GUIDE Parked Regeneration Regeneration of the Aftertreatment Device (ATD) is fundamental for the oxidation of soot. This process happens during the normal operation cycle of the vehicle; it can occur both passively and actively. Regardless of this, the operator will see no difference in vehicle performance or vehicle control. If the ATD is not capable of completing regeneration due to duty cycle constraints or other restrictions, a parked regeneration may need to occur. The driver will be notified of the need for a parked regeneration by illumination of the Diesel Particulate Filter (DPF) lamp as listed in Table 3. If the driver continues to operate the vehicle without a regeneration, additional measures will be taken to protect the engine and ATD device from damage, up to and including engine shutdown. The sequence of indicator lamp(s) is as follows: 1. The DPF Regeneration Lamp will be illuminated prior to any engine protection measures being taken. Once this lamp is lit, the parked regeneration process should be initiated. 2. If no DPF regeneration occurs after the initial DPF Regeneration Lamp illumination, the lamp All information subject to change without notice. (Rev. 04/08) will begin blinking and a parked regeneration should be initiated as soon as possible. If the flashing DPF is still ignored, the AWL (Check Engine), listed in Table 3, will illuminate. This will be accompanied by a 25% engine torque reduction. 3. If parked regeneration is still not initiated, a standard 60 second engine shutdown sequence will occur. All of the following dashboard lamps will be present, blinking DPF Regeneration Lamp, solid AWL (Check Engine), and solid Red Stop Lamp (RSL)/Stop Engine, listed in Table 3. Once this engine shutdown sequence is completed, a parked regeneration must occur to continue vehicle operation. If the driver continues to operate the vehicle without a regeneration, additional measures will be taken to protect the engine and ATD device from damage, up to and including engine shutdown. Described below is the procedure for performing a parked regeneration. NOTE: If the DDEC VI electronics have not requested the initiation of a parked regeneration (the DPF Regeneration Lamp is not illuminated), the regen request switch is disabled. DDC-SVC-MAN-0040 0704 Copyright © 2008 DETROIT DIESEL CORPORATION 63 AFTERTREATMENT SYSTEM HOT EXHAUST During parked regeneration the exhaust gases will be extremely HOT and could cause a fire if directed at combustible materials. The vehicle must be parked outside. NOTE: The driver MUST stay with the vehicle throughout the regeneration process. NOTE: Not all vehicles may be equipped with a regen request switch due to application or user specification. NOTE: The procedure will take 20 to 40 minutes (depends on engine type and the amount of soot accumulated in the filter). To initiate a parked regeneration, the following must occur: □ Locate Regen request switch on dash board. This is a momentary style switch see Figure 26 □ If no regen request switch is present, DDDL 7.0 must be connected for initiation using the service routines menu. Select “DPF Regen Request Start.” 64 Figure 26 Regen Request Switch □ Cycle the park brake OFF to ON – once an ignition cycle □ Cycle the clutch pedal (if configured) – once an ignition cycle □ Park Brake must be ON and the clutch must be released □ Engine should be on the idle governor (can not be in Fast Idle or PTO Mode) □ The engine should be fully warmed up and operating on thermostat temperature (>60°C) □ For J1939 transmissions, the transmission must be in neutral (confirmed by the J1939 data link – current gear and selected gear is 0) □ Vehicle speed must be 0 mph □ Hold the Regen Switch to the ON position for five seconds and release All information subject to change without notice. (Rev. 04/08) DDC-SVC-MAN-0040 0704 Copyright © 2008 DETROIT DIESEL CORPORATION MBE 900 ENGINE 2007 OPERATOR'S GUIDE When the request is accepted, the DPF Regeneration Lamp will turn on for one second and then go off for the rest of the parked regeneration. The engine speed will increase to 1200 rpm. With completion of regeneration, the following should occur: □ The HEST lamp will remain illuminated until the exhaust outlet temperature is below 525°C (977°F) or the vehicle speed exceeds 5 mph. □ The DPF regeneration lamp will turn off, along with all other associated warning lamps. If any of the above requirements are removed, the engine will return to idle. NOTE: This is for hazardous applications only. There are two CPC options: □ DPF Stationary Regen Only = 0 Disabled □ DPF Stationary Regen Only = 1 Enabled DPF Stationary Regen Only = 0-Disabled — This option allows the DPF Regeneration Switch to request a parked regeneration or an over-the-road regeneration. If the conditions previously mentioned are met, a parked regen will be initiated. If the conditions are not met, then the over-the-road regeneration will occur. To cancel the parked regeneration, the driver can toggle the Regen Switch to ON for five seconds. The DPF Regeneration Lamp will turn on for one second to show acceptance of the cancellation request and then return to the appropriate state as defined by the current level of soot in the DPF. DPF Stationary Regen Only = 1-Enabled — This option allows the DPF Regeneration Switch to only request a parked regeneration. If the conditions previously mentioned are met, a parked regen will be initiated. If the conditions are not met, nothing will happen. Hazardous Applications Service Record The MCM should be configured to not allow automatically triggered over-the-road regenerations (DPF Manual Regen Only Enable = Enabled).

Added benefits and savings occur when you check that the valves, fuel injectors, and oil and cooling circuits are in good working order during oil changes. The maintenance section of this manual explains when you should change your oil and what to look for when checking for wear or damage. For additional information, please contact your regional office. Scheduled Intervals All service intervals and maintenance operations are based on the parts and accessories expressly approved for your engine. The scope and frequency of maintenance work are determined by the engine's operating conditions: severe duty, short haul, long haul. Evidence of regular maintenance is essential if a warranty claim has to be submitted. If optional equipment is installed, be sure to comply with the maintenance requirements for these extra items. Important: If the engine is stored for more than 18 months, the oil must be 70 changed and the lubrication system must be primed before the engine can be brought into service. See MBE 900 Service Manual (6SE9007). Maintenance Schedule Types There are three types of maintenance schedule: □ (Severe Service) □ (Short Haul) □ (Long Haul) To determine which schedule to use, find the distance traveled by the vehicle in a year, regardless of vehicle type. Severe Service — Applies to vehicles that annually travel up to 6000 miles (10,000 kilometers) or that operate under severe conditions. Examples of Severe Service usage include: operation on extremely poor roads or where there is heavy dust accumulation; constant exposure to extreme hot, cold, salt-air, or other extreme climates; frequent short-distance travel; construction-site operation; city operation (fire truck, garbage truck); or farm operation. Short-Haul — Applies to vehicles that annually travel up to 60,000 miles (100,000 kilometers) and operate All information subject to change without notice. (Rev. 04/08) DDC-SVC-MAN-0040 0704 Copyright © 2008 DETROIT DIESEL CORPORATION MBE 900 ENGINE 2007 OPERATOR'S GUIDE under normal conditions. Examples of Short-Haul usage are: operation primarily in cities and densely populated areas; local transport with infrequent freeway travel; or high percentage of stop-and-go travel. Long-Haul — Long Haul (over-the-road transport) is for vehicles that annually travel more than 60,000 miles (100,000 kilometers), with minimal city or stop-and-go operation. Examples of Long-Haul usage are: regional delivery that is mostly freeway miles; interstate transport; or any road operation with high annual mileage. Maintenance Intervals — The three maintenance interval tables show which maintenance operation must be performed at the actual distances (in miles or kilometers) for each maintenance operation. The schedule of actual distances is based on the intervals given in the Maintenance Tables The three maintenance interval tables are:referred to in section Maintenance Tables □ Maintenance Interval Table, Severe Service ( listed in Table 7) Schedule Use Before placing your new vehicle in service, determine the correct maintenance intervals that apply to your intended use of the vehicle. Refer to section Maintenance Tables to determine the distance interval at which each maintenance operation must be performed to comply with your vehicle's schedule. When the vehicle reaches the actual distance given for an interval, refer to section Maintenance Tables. When maintenance is required for hours of engine operation refer to section Maintenance Tables.” Listed in Table 6 provides an engine hours conversion for applications that may require service intervals based on hours and not mileage. The intervals are based on a collaboration of field and fleet data. For a more accurate analyst of when fluids should be changed, such as engine oil, refer to publication Engine Requirements – Lubricating Oil, Fuel and Filters, (7SE270), available from authorized Detroit Diesel distributors. Complete each maintenance operation at the required interval. □ Maintenance Interval Table, Short Haul (listed in Table 8) □ Maintenance Interval Table, Long Haul (listed in Table 9) All information subject to change without notice.

(Rev. 04/08) DDC-SVC-MAN-0040 0704 Copyright © 2008 DETROIT DIESEL CORPORATION 75 MAINTENANCE Preventive Maintenance Intervals This section describes the items listed in the maintenance interval tables. As the operator of a vehicle, routine “Daily” inspections of the engine and chassis should be performed. This will provide the best opportunity to identify major concerns or concerns that would stretch a longer time span like slow coolant loss. For new or stored engines, Refer to section OPERATING INSTRUCTIONS FOR STARTING THE ENGINE in this guide. Item 1 – Lubricating Oil/ Filter it is fully inserted into the guide tube. Remove the dipstick and read the oil level dipstick. See Figure 27. The figure shows a comparison between the bends on the dipstick and a crosshatch pattern on a conventional dipstick. Note the exact area noted on the bends. For example, the “maximum” oil level will be at the BOTTOM of that bend. For the “minimum” oil level, it is noted at the TOP of the bend. If the oil level is below the “minimum” bend, add oil to bring it up the “maximum” level. Do NOT fill beyond the maximum fill level on the dipstick, since overfilling may result in high oil consumption and possible severe engine damage. Lubricating Oil: – Check the oil level daily with the engine stopped. If the engine has just been stopped and is warm, wait approximately 20 minutes to allow the oil to drain back into the oil pan before checking. Add the proper grade of oil to maintain the correct level on the dipstick. . Remove the dipstick from the guide tube. Note the dipstick has a positive locking device such as a lever or twist-lock design that must be disengaged before pulling the dipstick out of the guide tube. Use a shop rag to wipe off the end of the dipstick. Wait 15 seconds to allow any crankcase pressure to dissipate through the guide tube and let the oil level settle in the oil pan. Reinstall the dipstick and make sure 76 All information subject to change without notice. (Rev. 04/08) DDC-SVC-MAN-0040 0704 Copyright © 2008 DETROIT DIESEL CORPORATION MBE 900 ENGINE 2007 OPERATOR'S GUIDE Figure 27 Oil Dipstick NOTICE: When adding lubricating oil, do not overfill. Overfilling may result in high oil consumption and possible severe engine damage. All diesel engines are designed to use some oil, so the periodic addition of oil is normal. Before adding lubricating oil, refer to the How to Select Lubricating Oil section in this guide. Lubricating Oil Filter: – The oil filter is a cartridge style element and is located on the front right side of the engine. See Figure 28. If followed correctly, an oil filter change can be performed quickly with minimal oil cleanup. NOTICE: If the oil level is constantly above normal and excess oil has not been added to the crankcase, consult with an authorized Detroit Diesel service outlet for the cause. Fuel or coolant dilution of lubricating oil can result in serious engine damage. All information subject to change without notice. (Rev. 04/08) DDC-SVC-MAN-0040 0704 Copyright © 2008 DETROIT DIESEL CORPORATION 77 MAINTENANCE Item 2 – Cooling System Flush and Fill Coolant Flush and Fill – Proper maintenance of the cooling system is vital to its performance and longevity. The cooling system must, on a constant basis, deal with cavitation, temperature / pressure swings, and continuous threats on the additive package. Once the additives have been depleted from the coolant, it will only be a matter of time until the engine components suffer.Refer to the How to Select Coolant section in this guide. Figure 28 Lubricating Oil filter PERSONAL INJURY To avoid injury from slipping and falling, immediately clean up any spilled liquids. Make a visual check of all lubricating oil lines for wear and/or chafing. If any indication of wear is evident, replace the oil lines and correct the cause. Check for oil leaks after starting the engine. 78 Cooling System Inspection – Inspect the cooling system as follows: HOT COOLANT To avoid scalding from the expulsion of hot coolant, never remove the cooling system pressure cap while the engine is at operating temperature. Wear adequate protective clothing (face shield, rubber gloves, apron, and boots). Remove the cap slowly to relieve pressure. 1. Inspect the radiator, condenser, coolant pump, engine oil cooler, freeze plugs, and heat exchanger for damage and leaks. All information subject to change without notice. (Rev. 04/08) DDC-SVC-MAN-0040 0704 Copyright © 2008 DETROIT DIESEL CORPORATION MBE 900 ENGINE 2007 OPERATOR'S GUIDE 2. Check all cooling system pipes and hoses for damage and leaks; ensure they are positioned to avoid chafing, and are securely fastened. 3. Check the outside of the radiator and condenser for blockage. Check fins for damage; straighten them if necessary. Item 3 – Valve Lash Checking and Adjustment Valve lash checking and adjustment should be performed per the maintenance intervals prescribed under the proper service category for the engine, Refer to section Scheduled Intervals in this guide. All three service categories (Severe, Short Haul, and Long Haul) require a “first time” valve lash adjustment at a shorter interval. After the initial adjustment, all others are based on the same mileage intervals. Refer to section Maintenance Tables in this guide. Proper valve lash clearance allows the engine to produce the best possible performance with the lowest emissions. Valve lash adjustments should be performed by an authorized Detroit Diesel maintenance or repair facility. impose extra loads on the crankshaft, fan and/or alternator bearings, shortening both belt and bearing life. Excessively overtightened belts can result in crankshaft breakage. A loose belt will slip and generate excessive heat that may cause damage to the belt and accessory drive components. PERSONAL INJURY To avoid injury from rotating belts and fans, do not remove and discard safety guards. Belt Replacement – Drive belts (V and poly-V) should be replaced every 2,000 hours or 100,000 miles (160,000 km). After an extended time in service, minor rib cracks may appear, usually one or two cracks per inch is considered normal. See Figure 29 A concern occurs when the belt ribs exhibit severe multiple cracking or “chunking”. At this point, the belt should be replaced. Item 4 – Drive Belts Belts should be neither too tight nor too loose. Belts that are too tight All information subject to change without notice. (Rev. 04/08) DDC-SVC-MAN-0040 0704 Copyright © 2008 DETROIT DIESEL CORPORATION 79 MAINTENANCE Item 6 – Fuel Filters The final filter is housed within the fuel filter module. The filter element filters particles down 4 micron and is snapped into the cap. Item 7– Air System Figure 29 Minor Rib Cracking Auto Tensioner – Auto tensioners are usually maintenance free for the life of the engine. However, routine inspections should be performed. Uneven belt wear can indicate a loose, wore out, or bad bearing on the auto tensioner. A build up of dirt or grime around the front bearing surface of the wheel can indicate a future bearing failure due to inadequate lubrication. Air Cleaner – The air cleaner element should be inspected per the maintenance intervals or more often if the engine is operated under severe dust conditions. Replace the element, if necessary. Check the gaskets for deterioration and replace, if necessary. If the dry type air cleaner is equipped with an aspirator, check for aspirator damage or clogging. Clean, repair or replace, as necessary. Item 5 – Fuel / Water Separator Incorporated into the fuel filter module is a fuel/water separator. The separator removes emulsified water as well as droplets and is located in the lower compartment of the fuel filter module. An optional water in fuel sensor will indicate when the trapped water needs to be drained. If the water in fuel sensor is not available, periodic draining of the trapped water should be performed. 80 All information subject to change without notice. (Rev. 04/08) DDC-SVC-MAN-0040 0704 Copyright © 2008 DETROIT DIESEL CORPORATION MBE 900 ENGINE 2007 OPERATOR'S GUIDE NOTICE: Do not allow the air inlet restriction to exceed 5.5 kPa (22 in. H2O) under any engine operating conditions. A clogged air cleaner element will cause excessive intake restriction and reduced air supply to the engine resulting in increased fuel consumption, inefficient engine operation and reduced engine life. Inspect the entire air system for leaks daily. Look especially for torn air inlet piping or boots and loose or damaged clamps. Have worn or damaged parts repaired or replaced, as required. Retighten loose connections. Air Cleaner Replacement – Dry type air cleaner elements should be replaced after one year of service or when the maximum allowable air intake restriction has been reached, whichever comes first. Air-to-Air Charge Cooler – Periodically inspect the air-to-air charge cooler for buildup of dirt, mud, etc. and wash off using a mild soap solution. Check the charge cooler, ductwork, and flexible connections for leaks and have repaired or replaced, as required. inspected for leaks. The exhaust pipe rain cap should be checked for proper operation, if so equipped. With the introduction of an Aftertreatment system, the sealing of the exhaust system is critical and should be inspected regularly. Item 9– Air Compressor The air compressor incorporates three of the major systems of a diesel engine (air, lubrication, and coolant). Proper inspection of air compressor would include inspecting for air, oil, and coolant leaks. Due to inadequate internal sealing air compressors, when failed, can produce excessive crankcase pressure or allow an engine to ingest oil. Item 10 – Aftertreatment System (ATS) There is a need to periodically remove accumulated ash, derived from engine lube oil, from the filter. This ash does not oxidize in the filter during the regeneration process and must be removed through a cleaning procedure. All Detroit Diesel ATD equipped engines will illuminate a dashboard warning lamp indicating the need for ash cleaning.

(Rev. 04/08) DDC-SVC-MAN-0040 0704 Copyright © 2008 DETROIT DIESEL CORPORATION 81 MAINTENANCE Item 11 – Vibration Damper The viscous vibration damper should be inspected periodically and replaced if dented or leaking. See Figure 30. Item 12 – FEPTO Torsional Damper Checking Required Maintenance Operations The following sections describe the required maintenance operations . Engine Inspecting Inspect the engine as follows: 1. Visually check the engine for signs of leakage. A slight dampness at the sealing points is no cause for alarm. NOTE: More severe leaks, combined with a continual loss of oil, must be corrected without delay. 1. Vibration Damper Figure 30 Viscous Vibration Damper Heat from normal engine operation may, over a period of time, cause the fluid within the damper to break down and lose its dampening properties. For this reason the viscous vibration damper must be replaced at time of normal major engine overhaul, regardless of apparent condition. 82 2. Visually inspect all lines and hoses. Listen for any sound of leaking. Make sure all pipes and hoses are undamaged, correctly positioned to avoid chafing, and properly secured.

(Rev. 04/08) DDC-SVC-MAN-0040 0704 Copyright © 2008 DETROIT DIESEL CORPORATION MBE 900 ENGINE 2007 OPERATOR'S GUIDE HOW-TO SECTION This section covers Detroit Diesel's recommendations on how to select lubricating oil, diesel fuel, and coolant and includes basic engine maintenance procedures which can be performed by the operator. NOTICE: The manufacturer's warranty applicable to MBE 900 engines provides in part that the provisions of such warranty shall not apply to any engine unit that has been subject to misuse, negligence or accident. Accordingly, malfunctions attributable to neglect or failure to follow the manufacturer's fuel or lubricating recommendations may not be within the coverage of the warranty. How to Select Lubricating Oil The selection of the proper lubricating oil is important to achieve the long and trouble-free service which Detroit Diesel engines are designed to provide. The proper lubricating oil for model year 2007 MBE 900 engines is selected based on SAE viscosity grade and API (American Petroleum Institute) service designation. Figure 31 API Lubricant Symbol NOTICE: Lubricating oil must have a sulfated ash level less than 1.0 wt %; currently referred to as CJ-4 oil Lubricant Requirements API CJ-4 oils must be used in engines meeting January 2007, and later build, exhaust emission regulations. Cold Weather Starting At ambient temperatures below –20°C (–4°F) when sufficient starter speed cannot be achieved with SAE 15W-40 oils, the use of 5W-XX oils and 10W-XX oils (XX =30 or 40) is allowed to improve starting. Only oils licensed to display the API symbol should be used. See Figure 31. All information subject to change without notice. (Rev. 04/08) DDC-SVC-MAN-0040 0704 Copyright © 2008 DETROIT DIESEL CORPORATION 87 HOW-TO SECTION NOTICE: Monograde oils should not be used in MBE 900 engines, regardless of API service classification. Monograde oils gel at lower ambient temperatures, reducing lubricant flow, and they do not provide adequate lubricity at higher engine operating temperatures. These factors can result in severe engine damage. Figure 32 Engine Oil Temperature Ranges Synthetic Oils The oils must be API CJ-4 that have demonstrated field performance in Detroit Diesel engines. These oils must possess a High Temperature/High Shear (HT/HS) viscosity of 3.7 minimum. For further information, refer to publication Engine Requirements – Lubricating Oil, Fuel and Filters, 7SE270, available from authorized Detroit Diesel distributors. Synthetic oils may be used in Detroit Diesel engines, provided they are API licensed and meet the performance and chemical requirements of non-synthetic oils outlined in this publication. Synthetic oils offer improved low-temperature flow properties and high-temperature oxidation resistance. However, they are generally more costly than non-synthetic oils. Select the SAE class (viscosity) on the basis of the average air temperature for the season see Figure 32 Product information about synthetic oils should be reviewed carefully. Performance additive systems often respond differently in synthetic oils. NOTE: The use of synthetic oils does not permit extension of recommended oil drain intervals. 88 All information subject to change without notice. (Rev. 04/08) DDC-SVC-MAN-0040 0704 Copyright © 2008 DETROIT DIESEL CORPORATION MBE 900 ENGINE 2007 OPERATOR'S GUIDE The Use of Supplemental Additives Lubricants meeting the Detroit Diesel specifications outlined in this publication already contain a balanced additive treatment. Supplemental additives are generally not necessary and can even be harmful. These additives may be marketed as either oil treatments or engine treatments and are discouraged from use in Detroit Diesel engines. Engine damage resulting from the use of such materials is not covered by your Detroit Diesel Corporation warranty. Detroit Diesel will not provide statements beyond this publication relative to their use. Refer to section Maintenance Tables. for the maximum intervals at which the engine may operate before the oil and filters must be changed. Oil analysis may be used to determine whether this interval should be shortened, but it should not be used to lengthen the interval. The use of fuels with sulfur content above 0.05 mass percent will require a shortening of drain intervals and/or the use of a higher TBN oil. For detailed information refer to publication Engine Requirements – Lubricating Oil, Fuel and Filters (7SE270), available from authorized Detroit Diesel distributors. Disposing of Waste Oil When to Change Oil The length of time an engine may operate before an oil change depends upon the lubricant and fuel used, engine oil consumption, and the operating cycle. Dispose of used lubricating oil and filters in an environmentally responsible manner, according to federal (EPA) and/or state recommendations. The disposal of waste oil may be best addressed by the engine oil supplier, who may accept responsibility for proper disposal of this material as part of the business of providing lubricant. USED ENGINE OIL To avoid injury to skin from contact with the contaminants in used engine oil, wear protective gloves and apron. All information subject to change without notice. (Rev. 04/08) DDC-SVC-MAN-0040 0704 Copyright © 2008 DETROIT DIESEL CORPORATION 89 HOW-TO SECTION How to Replace the Lube Oil and Filters Filters are an integral part of the fuel system. Proper filter selection and maintenance are important to satisfactory engine operation and service life. Filters should be used to maintain a clean system, not to clean up a contaminated system. FIRE To avoid injury from fire, keep open flames, sparks, electrical resistance heating elements, or other potential ignition sources away when draining lubrication oil. Do not smoke when draining lubricating oil. NOTE: Select the SAE class (viscosity) on the basis of the average air temperature for the season. See Figure 33. View the temperature ranges for the various SAE classes as guidelines which can be exceeded for only a short time. 90 Figure 33 SAE Oil Viscosity Classes To insure the engine is protected and the oil stays clean until the next oil change, use only oils of API classification CJ-4. Only the 260 – 350 horsepower models (except motorcoach) have an oil centrifuge along with an oil filter. NOTICE: Both the primary lube oil filter (front of engine) and the oil centrifuge cartridge (side of engine) must be replaced at each oil drain interval.

Figure 37 Oil Centrifuge Housing Oil Centrifuge The fuels used must be clean, completely distilled, stable, and non-corrosive. For more information regarding the significance of these properties and selection of the proper fuel, refer to publication, Engine Requirements – Lubricating Oil, Fuel and Filters (7SE270), available from authorized Detroit Diesel distributors. How to Select Diesel Fuel Detroit Diesel engines in 2007 are designed to operate ONLY on Ultra-Low Sulfur Diesel (ULSD) fuel. See Figure 38. All information subject to change without notice. (Rev. 04/08) DDC-SVC-MAN-0040 0704 Copyright © 2008 DETROIT DIESEL CORPORATION 93 HOW-TO SECTION NOTICE: Use only Ultra-Low Sulfur Diesel (ULSD) fuel with (15 ppm sulfur content maximum), based on ASTM D2622 test procedure. Using fuel other than ULSD will damage the Aftertreatment Device. Fuel Contamination Generally, fuel contamination occurs as the result of improper fuel handling. The most common types of contamination are water, dirt, and microbial growth (“black slime”). The formation of varnishes and gums resulting from poor stability or extended storage (“stale fuel”) also affects fuel quality. The best treatment for contamination is prevention by maintaining a clean storage system and choosing a reputable fuel supplier. Supplemental additives are not recommended due to potential injector system or engine damage. Our experience has been that such additives increase operating costs without providing benefit. The use of supplemental fuel additives does not necessarily void the engine warranty. However, repair expenses which result from fuel system or engine component malfunctions or damage attributed to their use will not be covered. 94 These products should be accompanied by performance data supporting their merit. It is not the policy of Detroit Diesel Corporation to test, evaluate, approve or endorse such products. Biodiesel — Biodiesel fuels meeting ASTM D 6751 specification, prior to blending can be mixed up to 5% maximum by volume in petroleum diesel fuel. Detroit Diesel highly recommends biodiesel fuels made from soybean or rapeseed oil through the proper transesterification reaction process. Other feedstock source of biodiesel fuels such as animal fat or cooking oils are not recommended by Detroit Diesel. The resulting mixture must meet ASTM D 975 specification. More information is available in the Detroit Diesel publication Lubricating Oil, Fuel, and Filters (7SE270). Failures attributed to the use of biodiesel fuel will not be covered by Detroit Diesel product warranty. Also, any engine performance problem related to the use of biodiesel fuel would not be recognized nor considered Detroit Diesel's responsibility. Prohibited Additives The following fuel additives are not allowed and MUST NOT be mixed with diesel fuel: All information subject to change without notice. (Rev. 04/08) DDC-SVC-MAN-0040 0704 Copyright © 2008 DETROIT DIESEL CORPORATION MBE 900 ENGINE 2007 OPERATOR'S GUIDE Used Lubricating Oil — Do not use fuel blended with used lubricating oil. Detroit Diesel specifically prohibits the use of used lubricating oil in diesel fuel. NOTICE: Burning used lubricating oil in fuel cannot be tolerated as it will cause the diesel particulate filter to prematurely plug with ash. Used lubricating oil contains combustion acids and particulate materials which can severely erode fuel injector components, resulting in loss of power and increased exhaust emissions. In addition, the use of drained lubricating oil will increase maintenance requirements due to filter plugging and combustion deposits. Fuel Additives with Sulfur or Sulfated Ash — Do not use non-approved fuel additives containing sulfur or sulfated ash. Gasoline — The addition of gasoline to diesel fuel will create a serious fire hazard. The presence of gasoline in diesel fuel will reduce fuel cetane number and increase combustion temperatures. All information subject to change without notice. (Rev. 04/08) FIRE To avoid increased risk of a fuel fire, do not mix gasoline and diesel fuel. Tanks which contain a mixture of gasoline and diesel fuel should be drained and cleaned as soon as possible. Detroit Diesel Corporation will not be responsible for any detrimental effects it determines resulted from adding drained lubricating oil or gasoline to the diesel fuel. How to Replace the Fuel Filter/Water Separator Filters Filters are an integral part of the fuel system. Proper filter selection and maintenance are important to satisfactory engine operation and service life. Filters should be used to maintain a clean system, not to clean up a contaminated system.

How to Select Coolant This section covers selection of the required coolant for MBE 900 engines. Definitions To help ensure complete understanding of the information, the definitions of the following terms are provided: Antifreeze — Ethylene glycol or propylene glycol containing a corrosion inhibitor package and which meets an appropriate heavy-duty specification (i.e., TMC RP-329 “Type A” for ethylene glycol or TMC RP-330 “Type A” for propylene glycol). Coolant — The fluid mixture circulating in the engine cooling system, typically a mixture of 50% water and 50% antifreeze. Initial–Fill Coolant — The coolant that is used in a new or rebuilt engine, or any time the cooling system is emptied and then refilled with coolant. OAT — Organic Acid Technology. An inhibitor system based on organic acid inhibitors, instead of traditional North American inhibitor formulations. SCA — Supplemental Coolant Additive. SCAs are used in a preventive maintenance program to prevent corrosion, cavitation, and the formation of deposits. Approved Coolants The approved and preferred coolants for MBE 900 engines are listed in Table 12. Once installed, these coolants should be maintained according to the procedures discussed under Maintenance in this section. Drop–Out — Precipitated sludge or deposit formation on cooling system components. Fully Formulated Antifreeze — Contains all the necessary inhibitors to protect a diesel engine, and does not, therefore, require a pre-charge of SCA before its first use. All information subject to change without notice. (Rev. 04/08) DDC-SVC-MAN-0040 0704 Copyright © 2008 DETROIT DIESEL CORPORATION 101 HOW-TO SECTION NOTICE: Required specifications for water, ethylene glycol, propylene glycol, inhibitor packages and inhibitor concentration are included in this section. To avoid possible engine damage from inadequate or over concentrated coolant, this information should be read thoroughly before the coolant is replaced.

They are commercially available from Detroit Diesel (recommended) and other manufacturers as either 102 a concentrated antifreeze or as a pre-mixed antifreeze. The pre-mixed antifreeze is ready for use, while the concentrated coolant must be mixed with water prior to use. All information subject to change without notice. (Rev. 04/08) DDC-SVC-MAN-0040 0704 Copyright © 2008 DETROIT DIESEL CORPORATION MBE 900 ENGINE 2007 OPERATOR'S GUIDE Detroit Diesel Power Cool engine coolant (part number 23512138) is the preferred ethylene glycol (EG) coolant. If other commercial brands of ethylene glycol are used, they must be equivalent to the Power Cool. Detroit Diesel does not market a propylene glycol (PG) coolant. If a propylene glycol coolant is used, it must also meet the following requirements: □ Fully formulated ethylene glycol-based, low silicate antifreeze or coolant must meet TMC RP-329 “Type A” requirements. (50% antifreeze, 50% water) is recommended. An antifreeze concentration over 67% (67% antifreeze, 33% water) is not recommended due to poor heat transfer, reduced freeze protection (IEG only), and possible silicate dropout. An antifreeze concentration below 33% (33% antifreeze, 67% water) offers too little freeze and/or corrosion protection and is not recommended. □ Fully formulated propylene glycol-based antifreeze or coolant must meet TMC RP-330 “Type A” requirements. Fully formulated antifreeze does not require a dosage of SCA prior to initial use. Mixing EG or PG Antifreeze and Water — If a concentrated ethylene glycol (EG) or propylene glycol (PG) antifreeze is purchased, mix the antifreeze with water meeting the required quality standardslisted in Table 15 and fill the cooling system. If a pre-diluted, fully formulated coolant is purchased, fill the cooling system.

(Rev. 04/08) DDC-SVC-MAN-0040 0704 Copyright © 2008 DETROIT DIESEL CORPORATION 103 HOW-TO SECTION Always verify that the freeze point and nitrite concentration of the antifreeze/water mixture are correct by using a POWER Trac® 3–Way Coolant Test Strip. If chemical analysis is used, elements in the coolant must fall within the limits listed in Table 13. Fully Formulated Glycol Coolant Concentration Limits Table 13 Boron 125 – 500 PPM Nitrite 900 – 3200 PPM Nitrate 200 – 1000 PPM Silicon 50 – 250 PPM Phosphorous 0 PPM pH 8.0 – 11.0 Fully Formulated Glycol Coolant Limits with TMC RP-329, TMC RP-330 Chemistry Type A (50/50 Coolant/Water Mixture) Recycled Antifreeze — Antifreeze or coolant recycled by reverse osmosis, distillation, and ion exchange, properly re-inhibited to meet TMC RP-329 Type A or TMC RP-330 Type A requirements, has been demonstrated to provide service equivalent to virgin antifreeze. Recycled antifreeze or coolants of these types are preferred. Other recycled coolants, especially coolants recycled through filtration processes, are not recommended. EG/Water + OAT Inhibitor or PG/Water + OAT Inhibitor — Ethylene glycol and propylene glycol are also available with a OAT corrosion package. These coolants 104 require less maintenance over the useful life of the engine. OAT coolants, maintained as detailed in the Maintenance section of this guide, may be operated up to 4 years, 600,000 miles (960,000 km), or 10,000 operating hours, whichever comes first. Refer to Coolant Inhibitor Test Intervals in this guide. The cooling system should either be equipped with a blank coolant filter, or the coolant filter and piping may be omitted from the system. OAT fully formulated antifreezes are available as concentrated and pre-mixed. Concentrated antifreezes should be mixed 50% (50% antifreeze, 50% water). All information subject to change without notice. (Rev. 04/08) DDC-SVC-MAN-0040 0704 Copyright © 2008 DETROIT DIESEL CORPORATION MBE 900 ENGINE 2007 OPERATOR'S GUIDE OAT coolants should not be mixed with conventional coolants. If they are mixed, no damage will result, but the long-life advantages of the OAT coolant will be lost. In this event, the coolant should be maintained as a fully formulated Inhibited Ethylene Glycol (IEG) coolant, not as an Organic Acid Technology (OAT) coolant. Detroit Diesel markets a OATinhibited ethylene glycol coolant, DDC Power Cool Plus, which contains all the required additives. If a non-DDC OAT antifreeze is used, it must conform to TMC 338 specification. Do not add extender to new OAT antifreeze or coolant. Water Only + SCA or Water Only + OAT Inhibitor — In warm climates a coolant based on water with corrosion inhibitors is approved for use. Water-only systems need to be treated with the proper dosage of corrosion inhibitors. Detroit Diesel-approved SCAs or OAT corrosion inhibitors must be added to the water to provide required corrosion and cavitation erosion protection. OAT inhibitors such as Power Cool Plus 6000 are available for water-only systems. Inhibitor should be mixed at 7.5% – 10% by volume with water. For a list of Power Cool products,refer to section POWER COOL ENGINE PRODUCTS in this guide. Traditional SCA (Power All information subject to change without notice. (Rev. 04/08) Cool 3000) can also be used to protect the engine. Power Cool 3000 concentration limits are listed in Table 14. NOTE: Do not use Power Trac 3–Way Test Strips to test OAT coolant. POWER COOL® 3000 SCA inhibitors should be mixed at 5% by volume with water. This is 1 quart per 5 gallons of water. These additions can be made by adding liquid SCAs available in a variety of sizes. Coolant filters are also available for different cooling system capacities. These filters release the proper amount of SCA at initial fill.

(Rev. 04/08) DDC-SVC-MAN-0040 0704 Copyright © 2008 DETROIT DIESEL CORPORATION MBE 900 ENGINE 2007 OPERATOR'S GUIDE All Antifreezes And Coolants Containing Phosphate — These coolants are not recommended. Drop out, overheating and water pump seal failures can result from the use of coolant or inhibitor packages based on phosphate. Water Requirements — Distilled, reverse osmosis-purified, or de-ionized water which eliminates the adverse effects of minerals in tap water is preferred. High levels of dissolved chlorides, sulfates, magnesium, and calcium in some tap water causes scale deposits and/or corrosion resulting in water pump failures and poor heat transfer, leading to overheating. If tap water is used, the mineral content in the water must be below the maximum allowable limits listed in Table 15. Automotive Type Coolants — These coolants generally contain high levels of phosphate and silicate, offer no liner pitting protection, and are not suitable for use in Detroit Diesel engines. NOTICE: Methyl Alcohol-Based Antifreeze — This must not be used because of its effect on the non-metallic components of the cooling system and its low boiling point. Do not add additional SCA to new, fully formulated antifreeze or coolant. This can result in dropout and/or the formation of deposits. Coolants Not Recommended The following coolants are not recommended for use in Detroit Diesel engines.

These coolants generally contain high levels of phosphates, which can deposit on hot internal engine surfaces and reduce heat transfer. oil additives may result in engine overheating and/or failure. Chromate — Chromate additives are not approved for use in Detroit Diesel engine cooling systems. Chromate additives can form chromium hydroxide, commonly called “green slime.” This, in turn, can result in engine damage due to poor heat transfer. Cooling systems operated with chromium-inhibited coolant must be chemically cleaned with Power Cool dry chemical cooling system cleaner/conditionerrefer to section POWER COOL Cooling System Cleaners (or equivalent sulfamic acid/sodium carbonate cleaner) and flushed. Additives Not Recommended The following additives are not recommended for use in MBE 900 engines. Soluble Oils — Soluble oil additives are not approved for use in Detroit Diesel engine cooling systems. A small amount of oil adversely affects heat transfer. For example, a 1.25% concentration of soluble oil increases fire deck temperature 6%. A 2.50% concentration increases fire deck temperature 15%. The use of soluble Coolant Inhibitor Test Intervals The coolant inhibitor level should be checked at the intervals listed in Table 16. Inhibitor Test Interval Service Application Long Haul — Highway Trucks and Motor Coaches — operates more than 60,000 miles (100,00 km) per year Short Haul — City Transit — operates up to 60,000 miles (100,000 km) per year.

Maintenance Intervals — Check the nitrite concentration at the regular intervals listed in Table 17 with a Power Trac 3–Way Test Strip. If topping off is needed, add coolant which is identical to the initial fill coolant. Supplemental Coolant Additives for Fully Formulated Coolant — The concentrations of some inhibitors will gradually deplete during normal engine operation. SCAs replenish the protection for cooling system components. The coolant must be maintained with the proper concentration of SCA. Detroit Diesel Power Cool maintenance SCAs are recommended. The proper application of SCA will provide: □ pH control. □ Restored inhibitor levels to prevent corrosion. □ Water softening to deter formation of mineral deposits.

(Rev. 04/08) DDC-SVC-MAN-0040 0704 Copyright © 2008 DETROIT DIESEL CORPORATION MBE 900 ENGINE 2007 OPERATOR'S GUIDE NOTICE: Failure to properly maintain coolant with SCA can result in damage to the cooling system and its related components. Conversely, over-concentration of SCA inhibitor can result in poor heat transfer, leading to engine damage. Always maintain concentrations at recommended levels. Do not use traditional SCAs with OAT coolant. Additional SCA must be added to the coolant when it becomes depleted, as indicated by a nitrite concentration of 900 PPM or less. If the nitrite concentration is greater than 900 PPM, do not add additional SCA. If the nitrite concentration is above 3200 PPM, the system is over-inhibited and should be partially drained and filled with a 50/50 mix of water and EG or PG. In this case the EG or PG should contain no inhibitors and should conform to ASTM D4985. This will dilute the over-concentrated inhibitors. All information subject to change without notice. (Rev. 04/08) NOTE: In non-OAT systems, nitrite concentration of 5000 PPM or higher on an MBE 900 engine suggests problematic additive over-concentration. This condition must be corrected by immediate draining and flushing of the cooling system. Refill the system with new fully formulated or pre-charged coolant. Check the nitrite concentration level at the next maintenance interval with a Power Trac 3–Way Test Strip. SCA Test Procedures Detroit Diesel Power Trac 3–Way Coolant Test Strips should be used to measure nitrite and glycol concentrations. Part numbers are in refer to section POWER COOL ENGINE PRODUCTS. Cavitation/corrosion is indicated on the strip by the level of nitrite concentration. Freeze/boil over protection is determined by glycol concentration. DDC-SVC-MAN-0040 0704 Copyright © 2008 DETROIT DIESEL CORPORATION 111 HOW-TO SECTION Discard unused strips if they have turned light pink or tan. HOT COOLANT To avoid scalding from the expulsion of hot coolant, never remove the cooling system pressure cap while the engine is at operating temperature. Wear adequate protective clothing (face shield, rubber gloves, apron, and boots). Remove the cap slowly to relieve pressure. For best results make the test while the coolant is between 50° – 140° F (10.0° – 60° C). Wait at least 60, but not longer than 75, seconds before reading the nitrite level. Use the test strips as follows: 1. Dip the strip into coolant for one second. Remove and shake briskly to eliminate excess fluid. 2. Immediately compare the pad end (% glycol) to the color chart on the container. 3. Sixty seconds (one minute) after dipping, compare the nitrite pad to the color chart. 4. Color change of the additive indicator (middle pad) indicates the presence of inhibitor that is not approved by Detroit Diesel. A factory coolant analysis program is available through authorized Detroit Diesel service outlets. Part numbers are inrefer to section POWER COOL ENGINE PRODUCTS and refer to section POWER TRAC Coolant Testing And Analysis Products in the Specifications section. To verify coolant acceptability, submit a sample for coolant analysis every two (2) years, 300,000 miles (480,000 km), or 10,000 operating hours, whichever comes first. Need Release Coolant Filters (Non-OAT Systems) Spin-on coolant filters are available for Detroit Diesel engines. Membranes in the filters release SCAs before the coolant approaches a corrosive condition, protecting the engine from corrosion. The elements release the SCA charge as needed, as opposed to the maintenance SCA elements, which instantaneously release the SCA charge. Coolant filter elements should be replaced after one (1) year, 120,000 miles (192,000 km) or 2,000 operating hours, whichever comes first. Promptly replace and tighten the test strip container cap after each use. 112 All information subject to change without notice. (Rev. 04/08) DDC-SVC-MAN-0040 0704 Copyright © 2008 DETROIT DIESEL CORPORATION MBE 900 ENGINE 2007 OPERATOR'S GUIDE Dropout Excessive amounts of some inhibitors in the coolant can cause a gel or crystalline deposit that reduces heat transfer and coolant flow. The deposit, called “dropout,” takes the color of the coolant when wet, but appears as a white or gray powder when dry. It can pick up solid particles in the coolant and become gritty, causing excessive wear of water pump seals and other cooling system components. PERSONAL INJURY To avoid injury when using caustic cleaning agents, follow the chemical manufacturers usage, disposal, and safety instructions. Coolant Extender Inhibitor Additive for “OAT” Coolant The inhibitors in OAT coolant must also be maintained, but less often than traditional SCA-type coolants. A portable test is available to test the levels of OAT inhibitors in coolant. Where this is not used, fleet testing has determined that a OAT coolant extender package should be added to the coolant at 300,000 miles (480,000 km), two (2) years, or 5,000 hours, whichever comes first. The proper maintenance dosages for all OAT coolants are listed in Table 17 , reflecting 0.6% by volume extender. This dosage should be added to the water-only and the glycol systems at the same interval. The proper application of extender to OAT coolant will provide: □ pH Control The wet gel can be removed by using a non-acid (alkali) type heavy-duty cleaner, such as Detroit Diesel Power Cool On-Line Cleaner (sodium nitrite/sodium tetraborate). Part numbers are refer to section POWER COOL ENGINE PRODUCTS. NOTE: If the gel is allowed to dry, it is necessary to disassemble the engine and clean it with a caustic solution or physically clean individual components. All information subject to change without notice. (Rev. 04/08) □ Restored inhibitor levels to prevent corrosion □ Cavitation protection to protect wet sleeve cylinder liners NOTE: Do not use traditional SCAs in OAT coolant, and do not use OAT extender in traditional coolant. DDC-SVC-MAN-0040 0704 Copyright © 2008 DETROIT DIESEL CORPORATION 113 HOW-TO SECTION OAT Coolant Drain Interval — A properly maintained OAT-inhibited coolant will last 600,000 miles (960,000 km), four (4) years, or 10,000 operating hours, whichever comes first. At this time the coolant should be drained, and the cooling system should be thoroughly cleaned, flushed, and filled with new, properly inhibited OAT coolant. Chronic Coolant System Problems The most commonly seen coolant system problems result from maintenance and formulation factors such as: □ Hard water □ Dilution of the coolant by the addition of untreated water □ Over dosage or under dosage of corrosion inhibitors □ Improper corrosion inhibitor (most often phosphated) □ Mixing SCAs □ Improper testing Detroit Diesel Cooling System Maintenance Products The following products are available to do maintenance on the cooling system. 114 Power Cool SCAs — Power Cool SCAs are water-soluble chemical compounds. These products are available in coolant filter elements, liquid packages, and in fully formulated Power Cool antifreeze. NOTE: Power Cool 3000 liquid SCA is more compatible with hard water than Power Cool 2000 SCA. Power Cool Coolant Filter Elements — Power Cool coolant filter elements (spin-on canisters) are available in various sizes suitable for cooling systems of varying capacities. Selection of the proper element size is vital when pre-charging non-fully formulated coolant at initial fill and at maintenance intervals. A fully formulated antifreeze must not have SCA added at initial fill. Do not use SCA-containing filters with OAT antifreeze or coolant. The need for maintenance elements is determined by the results of the nitrite concentration test performed at each cooling system interval. Do not automatically install maintenance elements at maintenance intervals, unless the nitrite concentration falls below 900 parts per million. Power Cool Cleaners — Power Cool Liquid On-Line Cleaner is used for light deposits. Power Cool Dry All information subject to change without notice. (Rev. 04/08) DDC-SVC-MAN-0040 0704 Copyright © 2008 DETROIT DIESEL CORPORATION MBE 900 ENGINE 2007 OPERATOR'S GUIDE Chemical Cleaner/Conditioner is used for heavy deposits or scale. Summary of Coolant Recommendations HOT COOLANT To avoid scalding from the expulsion of hot coolant, never remove the cooling system pressure cap while the engine is at operating temperature. Wear adequate protective clothing (face shield, rubber gloves, apron, and boots). Remove the cap slowly to relieve pressure. 1. Always maintain the engine coolant to meet Detroit Diesel specifications. 2. Only use water that meets the specifications listed in Table 15. Distilled, de-mineralized (reverse osmosis) or de-ionized water is preferred. 3. The proper dosage of inhibitors must be included in the coolant at initial fill for all Detroit Diesel engines. This dosage is usually included in the fully formulated antifreeze used, or it may need to be added if water alone or if less than 50% antifreeze is used. The user is urged to refer to the full All information subject to change without notice. (Rev. 04/08) text of this section to determine the proper dosage. Mixing of different manufacturers' technologies (brands) could cause cooling system problems. 4. Maintain the inhibitor at the prescribed concentration. Test the nitrite concentration by using a titration kit or Detroit Diesel Power Trac 3-Way Coolant Test Strips. Add SCA only if the nitrite concentration is below 900 PPM. Do not use SCA in OAT coolant, and do not use Power Trac 3-Way Coolant Test Strips to test OAT coolant. NOTE: If the nitrite concentration exceeds 3200 PPM, the coolant must be drained and replaced with new coolant. A thorough cleaning of the cooling system may be required. 5. Do not use another manufacturer's test kit to measure the SCA concentration of Detroit Diesel maintenance products. 6. Pre-mix coolant makeup solutions to the proper concentration before adding to the cooling system. 7. Do not mix OAT and other coolants in the same engine. 8. Do not use automotive coolants. 9. Where antifreeze/boil over protection is required, use only DDC-SVC-MAN-0040 0704 Copyright © 2008 DETROIT DIESEL CORPORATION 115 HOW-TO SECTION antifreeze that meets TMC RP-329 “Type A” EG or TMC RP-330 “Type A” PG specifications. Always maintain coolant at the proper level. 10. Do not use the following in Detroit Diesel engine cooling systems: acceptability, submit a sample for coolant analysis every 300,000 miles (480,000 km), three (3) years, or 5,000 operating hours, whichever comes first. Submit the sample in a DDC Power Trac Coolant Test Bottle. Required part numbers are in refer to section POWER COOL ENGINE PRODUCTS. □ Soluble oil □ High silicate, automotive-type antifreeze □ Chromate SCAs □ Methoxy propanol-base coolant □ Methyl alcohol-base coolant □ Sealer additives or coolant containing sealer additives. □ HVAC coolant □ Phosphated coolants Coolant life of Glycol Coolant — A properly maintained cooling system, filled with phosphate-free coolant consisting of a 50/50 mix of antifreeze and water per TMC RP-329 “Type A” EG or TMC RP-330 “Type A” PG specifications can be operated to the limits recommended. The proper maintenance involves periodic evaluation using Power Trac 3-Way Coolant Test Strips and the addition of SCA as needed, indicated by the strip test. To verify coolant 116 Coolant Life of OAT Coolant — A properly maintained OAT coolant may be operated 600,000 miles (960,000 km), four (4) years, or until overhaul, whichever comes first. At this time the system must be completely drained, thoroughly cleaned, and refilled. OAT Coolants require the addition of an extender at 300,000 miles (480,000 km), two (2) years, or 5,000 hours, whichever comes first. Use 1 pint of extender for every 20 gallons of coolant. Coolant Life of Other Coolants — Other properly maintained coolants may be operated up to 250,000 miles (480,000 km), two (2) years, or 4,000 operating hours, whichever comes first. At this time the system must be completely drained, thoroughly cleaned, and refilled.

(Rev. 04/08) DDC-SVC-MAN-0040 0704 Copyright © 2008 DETROIT DIESEL CORPORATION 131 ENGINE STORAGE ENGINE STORAGE When an engine is to be stored or removed from operation for a period of time, special precautions should be taken to protect the interior and exterior of the engine, transmission and other parts from rust accumulation and corrosion. The parts requiring attention and the recommended preparations are given below. Preparing Engine for Storage It will be necessary to remove all rust or corrosion completely from any exposed part before applying rust preventive compound. Therefore, it is recommended that the engine be processed for storage as soon as possible after removal from operation. The engine should be stored in a building that is dry and can be heated during the winter months. Moisture-absorbing chemicals are available commercially for use when excessive dampness prevails in the storage area. Temporary Storage (30 Days or Less) To protect the engine for a temporary period of time (30 days or less), follow this procedure: 132 1. With the engine at ambient temperature and cool to the touch, drain engine crankcase oil into a suitable container. Dispose of the oil in an environmentally friendly manner, according to state and/or federal EPA recommendations. 2. Fill the crankcase to the proper level with the recommended viscosity and grade of oil. 3. Fill the fuel tank with the recommended grade of fuel oil. Operate the engine for two (2) minutes at 1200 rpm and no load. Do not drain the fuel system or the crankcase after this run. 4. Check the air cleaner and service it, if necessary. 5. If freezing weather is expected during the storage period, check the antifreeze/coolant for required freeze and inhibitor protection. Add antifreeze solution to the cooling system in accordance with Detroit Diesels recommendations. Refer to the How to Select Coolant in this guide. NOTE: If an antifreeze solution is not required during storage, flush the cooling system with a good soluble oil (3% – 5% by volume) rust inhibitor to prevent All information subject to change without notice. (Rev. 04/08) DDC-SVC-MAN-0040 0704 Copyright © 2008 DETROIT DIESEL CORPORATION MBE 900 ENGINE 2007 OPERATOR'S GUIDE rusting of the outside diameter of the cylinder liners. EYE INJURY To avoid injury from flying debris when using compressed air, wear adequate eye protection (face shield or safety goggles) and do not exceed 276 kPa (40 psi) air pressure. 6. Clean the exterior of the engine (except electrical parts) with fuel oil and dry with compressed air. 7. Seal all engine openings. The material used must be waterproof, vaporproof and possess sufficient physical strength to resist puncture and damage from the expansion of entrapped air. An engine prepared in this manner can be returned to service in a short time by removing the seals at the engine openings and by checking the engine coolant, fuel oil, lubricating oil and transmission oil levels. Extended Storage (More than 30 Days) To prepare an engine for extended storage (more than 30 days), follow this procedure: All information subject to change without notice. (Rev. 04/08) 1. Drain the cooling system and flush with clean, soft water. Refill with clean, soft water and add a rust inhibitor to the cooling system. 2. Circulate the coolant by operating the engine until normal operating temperature is reached. 3. Stop the engine. 4. With the engine at ambient temperature and cool to the touch, drain the engine crankcase oil into a suitable container. Remove the oil filters. Dispose of the oil and filters in an environmentally friendly manner, according to state and/or federal EPA recommendations. Replace the drain plug and tighten to 65 N·m (48 lb-ft) torque. 5. Install new lubricating oil filters. Fill the crankcase to the proper level with Tectyl® 930A preservative lubricating oil or an equivalent 30–weight preservative lubricating oil meeting Mil-L-21260C, Grade 2 Specification. 6. Drain the fuel tank. Refill with enough clean No. 1 diesel fuel or pure kerosene to permit the engine to operate for about ten (10) minutes. If draining the fuel tank is not convenient, use DDC-SVC-MAN-0040 0704 Copyright © 2008 DETROIT DIESEL CORPORATION 133 ENGINE STORAGE a separate, portable supply of recommended fuel. NOTE: If engines are stored where condensation of water in the fuel tank may be a problem, additives containing methyl carbitol or butyl cellusolve may be added to the fuel. Follow manufacturer's instructions for treatment. Where biological contamination of fuel may be a problem, add a biocide such as Biobor® JF (or equivalent) to the fuel. When using a biocide, follow the manufacturer's concentration recommendations and observe all cautions and warnings. 7. Drain the fuel system and remove the fuel filters. Dispose of used filters in an environmentally responsible manner, according to state and/or federal EPA recommendations. Fill the new filters with No. 1 diesel fuel or pure kerosene and install on the engine. 8. Operate the engine for five (5) minutes to circulate the clean fuel throughout the engine. Be sure the engine fuel system is full. 9. Stop the engine and allow to cool. Then disconnect the fuel return line and the inlet line at the primary filter and securely 134 plug both to retain the fuel in the engine. 10. Transmission: Follow the manufacturer's recommendations for prolonged storage. 11. Power Take-Off: If equipped, follow manufacturer's recommendations for prolonged storage. NOTICE: Failure to properly seal off the turbocharger air inlet and exhaust outlet openings before engine storage may permit air drafts to circulate through the turbocharger and rotate the turbine/compressor shaft without an adequate flow of lubricating oil to the center housing bearings. This can result in severe bearing damage. 12. Turbocharger: Since turbocharger bearings are pressure lubricated through the external oil line leading from the oil filter adaptor while the engine is operating, no further attention is required. However, the turbocharger air inlet and turbine exhaust outlet connection should be sealed off with moisture-resistant tape. 13. Apply a non-friction rust preventive compound to all All information subject to change without notice. (Rev. 04/08) DDC-SVC-MAN-0040 0704 Copyright © 2008 DETROIT DIESEL CORPORATION MBE 900 ENGINE 2007 OPERATOR'S GUIDE exposed engine parts. If convenient, apply the rust preventive compound to the engine flywheel. If not, disengage the clutch mechanism to prevent the clutch disc from sticking to the flywheel. NOTE: Do not apply oil, grease or any wax-base compound to the flywheel. The cast iron will absorb these substances, which can “sweat” out during operation and cause the clutch to slip. 14. Drain the engine cooling system. 15. Drain the preservative oil from the engine crankcase. Reinstall and torque the oil drain plug to 65 N·m (48 lb-ft). 16. Remove and clean the battery and battery cables with a baking soda-water solution and rinse with fresh water. Do not allow the soda solution to enter the battery. Add distilled water to the electrolyte (if necessary) and fully charge the battery. Store the battery in a cool (never below 0° C or 32° F) dry place. Keep the battery fully charged and check the level and specific gravity of the electrolyte regularly. 18. Seal all engine openings, including the exhaust outlet, with moisture-resistant tape. Use cardboard, plywood or metal covers where practical. 19. Clean and dry the exterior painted surfaces of the engine and spray with a suitable liquid automobile body wax, a synthetic resin varnish, or a rust preventive compound. 20. Protect the engine with a good weather-resistant tarpaulin and store it under cover, preferably in a dry building which can be heated during the winter months. Outdoor storage of the engine is not recommended. If units must be kept out of doors, follow the preparation and storage instructions already given. Protect units with quality, weather-resistant tarpaulins (or other suitable covers) arranged to provide for air circulation. 17. Insert heavy paper strips between the pulleys and drive belts to prevent sticking. All information subject to change without notice. (Rev. 04/08) DDC-SVC-MAN-0040 0704 Copyright © 2008 DETROIT DIESEL CORPORATION 135 ENGINE STORAGE NOTICE: Do not use plastic sheeting for outdoor storage. Plastic is fine for indoor storage. When used outdoors, however, enough moisture can condense on the inside of the plastic to rust ferrous metal surfaces and pit aluminum surfaces. If a unit is stored outside for any extended period of time, severe corrosion damage can result. The stored engine should be inspected periodically. If there are any indications of rust or corrosion, corrective steps must be taken to prevent damage to the engine parts. Perform a complete inspection at the end of one year and apply additional treatment as required. 3. Wash the exterior of the engine with fuel oil to remove the rust preventive. Do not wash electrical components. 4. Remove the rust preventive from the flywheel. Flush any soluble oil rust inhibitor (if used) in the cooling system. 5. Remove the paper strips from between the pulleys and drive belts. 6. Fill the crankcase to the proper level with the required grade of lubricating oil. Use a pressure lubricator to insure all bearings and rocker shafts are lubricated. 7. Fill the fuel tank with the required fuel. 1. Remove the covers and tape from all the openings of the engine, fuel tank and electrical equipment. Do not overlook the exhaust outlet. 8. Close all drain cocks and fill the engine cooling system with clean, soft water and required inhibitors. If the engine is to be exposed to freezing temperatures, install genuine Detroit Diesel Power Cool antifreeze or an equivalent ethylene glycol-base or propylene glycol-base antifreeze solution which provides required freeze, boil over, and inhibitor protection. “Refer to section How to Select Coolant” section in this guide. 2. Remove the plugs from the inlet and outlet fuel lines and reconnect the lines to their proper positions. 9. Install and connect the battery. Make sure the average specific gravity of the battery is 1.260 Procedure for Restoring to Service an Engine that Has Been in Extended Storage If an engine has been in extended storage, prepare it for service as follows: 136 All information subject to change without notice.
