4. DESCRIPTION
NOTE
Refer to specific data sheets for flow capacities and vacuum capacities.
NOTE
Refer to diagrams in this manual for proper rotation and orientation in inlet and discharge.
Tuthill Vacuum & Blower Systems model 1200 rotary lobe blowers are positive displacement type units, whose pumping capacity is determined by size, operating speed, and differential pressure conditions.
Blowers employ rotors rotating in opposite directions within a housing closed at the ends by end plates.
Effective sealing of the inlet to the discharge is accomplished through the use of very small operating clearances. The resulting absence of moving contact eliminates the need for any internal lubrication.
Clearances between the rotors during rotation are maintained by a pair of accurately machined helical timing gears, mounted on the two shafts extended outside the air chamber. The intermeshing rotary lobes are designed to rotate and trap air or gas between each rotor and the housing. As the rotor lobes rotate past the edge of the suction port, the trapped air or gas is essentially at suction pressure and temperature.
Since the blower is a constant volume device, the trapped air remains at suction pressure until the leading rotor lobe opens into the discharge port. The close clearances between the rotors inhibit back slippage of the trapped volume from between the rotors and the trapped volume is forced into the discharge piping.
Compression occurs not internal to the blower, but by the amount of restriction, either downstream of the blower discharge port, or upstream of the blower inlet port.
5
Figure 1 illustrates that the air moves not between the rotors but between the rotors and the side of the housing. Also, the machine is bi-directional, meaning that the direction of rotation of the blower can make either side the inlet or discharge. See also the Flow
Direction by Rotation section below.
INLET INLET INLET
No attempt should ever be made to control capacity by means of
DISCHARGE DISCHARGE DISCHARGE
Figure 1 - Illustration of general operation principle a throttle valve in the intake or discharge piping. This will increase the power load on the drive system, increase operating temperatures, and can overload and/or seriously damage the blower. Likewise, if a possibility exists that flow to the blower inlet may be cut off during normal operation of a process, then an adequate vacuum relief valve must be installed near the blower. A pressure type relief valve in the discharge line near the blower is also strongly recommended for protection against cutoff or blocking in this line. Check valves should also be used on every blower when more than one blower is connected to a discharge line. This is for both safety and operating conditions.
When a belt drive is employed, blower speed, if necessary, can usually be adjusted to obtain desired capacity by changing the diameter of one or both sheaves, or by using a vari-speed motor pulley. In a direct coupled arrangement, a variable speed motor or transmission is required, or excess air or gas may be blown off through a manually controlled unloading valve and silencer. Gas units can use bypasses, but some applications may require additional cooling. If there is a large volume of high pressure air or gas downstream of the blower, a check valve in the piping downstream of the blower will protect the blower from overspeeding in a backward direction upon shutdown.
Consult your Tuthill Vacuum & Blower Systems sales professional if questions arise.

WARNING
The maximum pressure differential is based on the difference between the inlet pressure and the outlet pressure. The maximum pressure differential shall not be exceeded. Exceeding the maximum pressure differential will cause serious damage to the equipment and could cause bodily injury.
WARNING
The maximum allowable working pressure (MAWP) is based on the absolute pressure of the blower housing and is NOT the maximum allowable pressure differential. Exceeding the MAWP will cause serious damage to the equipment and could cause bodily injury.
To permit continued satisfactory performance, a blower must be operated within certain approved limiting conditions. The manufacturer’s warranty is, of course, also contingent on such operation. Maximum limits for pressure, temperature and speed are specified here for various blower sizes when operated under the standard atmospheric conditions. Do not exceed any one of these limits.
NOTE
Specially ordered blowers with nonstandard construction, or with rotor end clearances greater than shown within the Assembly Clearances table, will not have the operating limits specified here. Contact your Tuthill Vacuum &
Blower Systems sales representative for specific information.
NOTE
Special attention must be paid when a blower has a higher than standard ambient suction temperature. Special recommendations for operating parameters and/or additional cooling may be recommended. Consult the factory or local representative for appropriate information.

5. INSTALLATION
5.1 GENERAL
DANGER
The blower is not intended to be used with explosive products or in explosive environments. The blower is not intended to be used in applications that include hazardous and toxic gases. Consult the factory for support.
DANGER
It is the responsibility of the installer to assue that proper guarding is in place and compliant with all applicable regulatory requirements.
WARNING
The bare shaft blower can generate excessive noise. Methods to reduce the noise levels by installing inlet and outlet silencers will be required. Even with inlet and outlet silencers, hearing protection will be required.
WARNING
Customers are warned to provide adequate protection, warning and safety equipment necessary to protect personnel against hazards in the installation and operation of this equipment in the system or facility.
WARNING
The standard MAWP is per Table 2. The MAWP shall not be exceeded unless specific factory testing of the pressure containing components of the blower has been performed.
WARNING
Table 2 states the maximum operating speed in RPM (rotations per minute) and maximum temperature. Do not exceed these limits. The installation of the booster shall take these critical operating parameters into account and adequate control features implemented.
WARNING
Upon completion of the installation, and before applying power, rotate the drive shaft by hand. It must move freely. If it does not, look for uneven mounting, piping strain, excessive belt tension or coupling misalignment or any other cause of binding. If blower is removed and still does not move freely, check inside the blower housing for foreign material.
NOTE
Remove the protective covers from the shaft and inspect for damage.
Carefully check to ensure that no transit damage has been sustained. If damage has occurred from shipment a claim must be filed with the carrier immediately; preserve the shipping container for inspection by the carrier.
8
NOTE
In the event that your unit sustains damage while being shipped to your facility, do not return it to the factory without first obtaining shipping instructions from us.
Protective covers and plugs should not be removed until the connection is being made. Mount the blower on a flat, level surface. We recommend a baseplate that is a rigid, solidly supported, and structurally sound. Shim under the legs where necessary so that each leg of the blower supports an equal share of the blower weight. This is necessary to prevent eventual twisting of the blower. Make sure feet rest evenly on the mounting surface before fastening down. Twisting or cramping the blower in mounting will cause rotor contact and binding during operation, resulting in a condition called “soft foot”. (See the Soft Foot section of this manual for further details and preventative measures.)
A unit that is factory mounted on a base, should not require the above adjustments. However, since the assembly can become twisted in shipping or installation, checking for soft foot should be done after installation of the base. Shims may be needed for alignment. Loosen the foot hold-down screws to check foot contact with the mounting surface. The base should be mounted on a solid foundation or heavy flooring, using shims as necessary at bolting points to prevent warping the assembly. (Also refer to the Foundation section.)
Transmission of small operating vibrations to a support structure may be objectionable in some cases. Use of vibration isolators or vibration absorbing materials can be effective in overcoming this problem. To avoid casing distortion, the treatment used should be applied under the common motor/blower base or mounting plate, rather than directly under the feet alone.
Piping should be accurately squared with the blower and supported independently. Stress imparted from incorrectly aligned piping or mounting will create problems with bearing and seal life, possibly leading to premature internal contact. The blower should sit stress free and evenly on its supporting surface. Care should be taken to evenly tighten the mounting bolts to not impart undue stress into the blower. Stress can be checked in a free state with feeler stock or verified on a previously installed blower with the aid of a dial indicator. Less than .002” (.05 mm) spring or gap should be found.
Use only clean new pipe and make certain it is free of scale, cuttings, weld beads, dirt, or any other foreign material. To guard against damage to the blower, insure that an inlet filter is used. Make provisions to clean the filter of collected debris after a few hours of operation and periodically thereafter. (See the Piping
Connections section for additional details.)
Figure 3 shows a typical complete installation of blower and accessories. Note the absence of throttle or shut-off valves in either discharge or intake piping. If it is possible for air flow to be cut off in either of these lines, make provisions to add a pressure and/or vacuum relief valve. In some installations, it may be desirable to use only an inlet silencer-cleaner supported directly from the blower connection.
Weight of accessories and piping must be kept to a minimum to prevent blower casing distortion. Weights in excess of 10% of blower weight should be supported independently of blower and connected with a flexible hose or connectors. (The approximate weight of your unit is included within the Specifications table.)

A blower may be driven by direct-coupling to the driver or by V-belt drive, to obtain other speeds within approved range. (See the Motor Drives section for more information.)
Blowers from Tuthill Vacuum & Blower Systems are internally and externally treated after factory assembly and testing to protect against rusting in normal atmospheric conditions prior to installation. The maximum period of internal protection is considered to be up to 6 months under average conditions, provided closing plugs and seals are not removed. Protection against chemical or salt water atmosphere is not provided.
Avoid opening the blower until ready to begin installation, as protection will be quickly lost due to evaporation.
(For recommended preparations for long term storage (longer than 6 months), please see the Long Term
Storage section in this manual.)
5.1.1 LOCATION
Install your blower in a room or outdoor area that supplies adequate space and lighting for routine maintenance. Indoor installation areas should be well ventilated and kept as cool as possible, because operating the unit at elevated temperatures can result in nuisance overload or temperature shutdowns. An unprotected outdoor installation is only satisfactory when correct lubrication for expected temperatures is provided, as per the Recommended Lubricants section in this manual.
5.1.2 FOUNDATION
Your blower does not need a special foundation, however it does require a solid, level floor and adequate frame support. Bolt the blower system to the floor and seal any cracks.
5.1.3 BLOWER AIR INTAKE
To minimize maintenance, supply your blower with the cleanest air possible. It is important that the air does not contain any flammable or toxic gases, as the blower will concentrate these gases. This could result in damage to the unit and surrounding property, lead to personal injury or death. Do not block or restrict the opening or the blower and/or motor may overheat and fail.
Do not use blowers on explosive or hazardous gases. Each size blower has limits on pressure differential, running speed, and discharge temperature. These limits must not be exceeded. Consult Table 2 for details pertaining to the allowable performance criteria.
If it is necessary to take air from a remote source, such as in a vacuum application, the piping should be at least the same diameter of the blower inlet. For distances greater than 20 feet (6 m) the pipe diameter should be enlarged to reduce inlet restriction. Excessive restriction will reduce the efficiency of the blower and elevate its discharge temperature. The piping used should also be corrosion resistant, and free of scale and dirt. The inlet should be covered to keep out precipitation, insects, and small animals. Vacuum kits are available.
10
5.1.4 SOFT FOOT
Soft foot is a condition in which one of the blower feet does not sit flat on the base. Usually, this is due to irregularities in the surface to which the blower is mounted. When you tighten the bolt on the foot, the blower will distort slightly, but enough to cause problems with bearing and seal life, and premature internal contact between the rotors and the housing.
1. Place blower on base.
2. Check each foot for gaps between foot and base (soft foot), shim as necessary to fill gap within .002” (.05 mm) Below are shown the two most common types of soft foot conditions. If either type is present, and measures more than .003” (.076 mm), the blower may fail prematurely.
3. Tighten all bolts.
4. Mount a dial indicator on base contacting one foot at 12 o’clock position.
5. Loosen bolt on that foot. Observe indicator travel and add shims as needed to reduce “spring” to less than .002” (.05 mm). Repeat steps 4 and 5 on remaining feet.

5.2 SAFETY
Tuthill Vacuum & Blower Systems recommends the use of relief valves to protect against excessive pressure or vacuum conditions. These valves should be tested at initial start-up to be sure they are properly adjusted to relieve at or below the maximum pressure differential rating of the blower.
DANGER
It is the responsibility of the installer to assure that proper guarding is in place and compliant with all applicable regulatory requirements.
DANGER
Internal and external rotating parts of the blower and driving equipment can produce serious physical injuries. The blower should never be run with the inlet or discharge piping removed. If it becomes necessary to inspect the rotating parts of the blower or to change V-belts, be absolutely sure that all power to the motor controls has been shut off, the motor controls are locked out, and properly tagged before proceeding.
DANGER
Assure that properly sized vacuum breaks/relief valves are used on the inlet side of the blower. Also assure that properly sized pressure relief valves are used on the outlet of the blower. The sizing shall be such to assure that the proper flow can be achieved without exceeding the rated vacuum and pressure ratings.
DANGER
Blower housing and associated piping or accessories may become hot enough to cause major skin burns on contact.
11
WARNING
Use lock out/tag out procedures to disable the electrical energy source before any service or work is done on the blower.
WARNING
Avoid extended exposure in close proximity to machinery with high intensity noise levels. Wear adequate ear protection.
NOTE
Use proper care and good procedures in handling, lifting, installing, operating, and maintaining the equipment.
5.3 LUBRICATION
Every blower from Tuthill Vacuum & Blower Systems is factory tested; oil drained and shipped dry to its installation point. Both oil reservoirs must be filled to the proper level before operation.
The blower incorporates pressure lubrication with an integral oil pump, pressure relief valve, filter and oil-tocoolant heat exchanger. Before starting the blower, fill oil sumps as shown below under “Filling Procedure”.
Tuthill Vacuum & Blower Systems approved mineral-based, synthetic and food grade lubricants are listed on page 35.
WARNING
Never attempt to change or add lubrication while the blower is running.
Failure to heed this warning could result in damage to the equipment or personal injury. Oil must be checked when the blower is NOT running.
WARNING
Properly dispose of the spent lubricants. Refer to the manufacturer of the lubricant and any regulations to assure proper and safe disposal.
WARNING
Do not start the blower until you are sure oil has been put in the gear housing and rear cover. Operation of the blower without proper lubrication will cause the blower to fail and void the warranty.
5.3.1 FILLING PROCEDURE
See Figure 5. Recommended lubricants are shown on page 35.
1. Remove fill plugs or breathers from both gear end and drive end plates.
2. SLOWLY pour oil through fill until oil appears in the oil sight glass. Bring oil level to center of sight glass.
3. Verify oil level is at proper level in BOTH gear end and drive end sight glasses.
4. Replace fill plugs or breathers that were removed in step 1.
The end cover oil reservoirs are connected together by passageways external to the rotor housing. To change oil, drain from the one-inch square head plug located in bottom of cover, or the on-half inch plug in the oil pump cover.
Oil levels should be checked frequently. Blower must be shut down to properly check oil level.

5.3.2 FREQUENTLY ASKED QUESTIONS REGARDING LUBRICATION
What is the functional detriment if the “wrong oil” is used?
The lubricant is selected based on bearing and gear speed, and operating temperature. Too light of a lubricant increases wear by not separating the sliding surfaces and it will not remove the heat adequately. If the lubricant is too thick, the drag in the bearings is increased causing them to run hotter.
Since it is thicker, it will not flow as readily into the gears and it will reduce the available backlash.
Lubricants at our conditions are incompressible.
What is the functional detriment if the oil is not serviced?
If the lubricant is not serviced at the proper interval the shearing action in the bearing and the gears will begin to take their toll and the lubricant will thicken, making matters worse. The unit will run hotter and the wear on running surfaces will increase. Generally, the lubricant will appear dirtier, this is actually material rubbed off the unit’s components. The discoloration comes from overheating the additive package. An indicator of the breakdown of a lubricant is the increase in the TAN (Total Acid Number), and a change in the base viscosity of ten percent.
Several things are happening as the lubricant goes through the unit. First, it is absorbing frictional energy in the form of heat. This heat has to be dissipated through either surface contact with cooler materials, or in a rest volume of lubricant. While reducing the friction, the lubricant is also going through a shearing process and the molecular structure is broken down.
The result is that the lubricant will begin to thicken because of the shorter molecular chains and the drop out of additive packages. The thickened lubricant will cause more drag, increasing the friction and heat, and further degrading the lubricant.
Operation of the blower (environment, run time, speed, and pressure) has a direct effect on duty cycles.
Our published cycles are based on worst-case conditions.

5.4.1 HAZARDS ASSOCIATED WITH BREAKDOWN OR IGNITION OF LUBRICATION
DANGER
There is a risk associated with the lubrication media breaking down and resulting in a hazardous fluid or vapor. There may also be a hazard associated with the ignition of the lubrication media. Refer to the lubrication manufacture’s applicable instruction for safety precautions.

5.4.2 LUBRICATION – INTEGRAL PRESSURE
5.4.3 OIL FILTER
The oil filter is self-contained. With every oil change, change the oil filter element and it’s shell gasket, both available from Tuthill Vacuum and Blower Systems in Springfield, Missouri, or from any authorized distributor or service center. Oil Filter Element (P/N 91999-1) Shell Gasket (P/N 12102-6)
CAUTION
Factory supplied filters are engineered to provide the proper restriction in the oil lubrication system. Using filters other than those available from
Tuthill Vacuum & Blower Systems may result in lubrication problems and possibly unwarrantable damage to the booster.
5.4.4 OIL PRESSURE ADJUSTMENT
The oil pressure on each unit has been preset at the factory during the load testing. Generally the oil pressure should not require adjustment once the unit is installed and in operation. Some adjustment may be required due to the speed and oil temperature.
The oil pump itself has no adjustment, however, the oil by-pass relief valve located in the oil feed line after the oil filter can be used for the same purpose.

REMOVE
TO ADJUST
To adjust the unit to the proper oil pressure, remove the hex cap shown in the image to the right. Loosen the lock nut and turn the
OUT
Figure 6 - Pressure Relief Valve set screw clockwise to increase the pressure or counterclockwise to decrease the pressure. Tighten lock nut and replace cap before reading oil pressure. Oil pressure may vary between 5 psig and 30 psig. The unit’s oil system can operate satisfactorily at 1 psig, if necessary, and still have sufficient flow. Always allow unit to reach operating temperature before adjusting the oil pressure to the proper range. Set the oil pressure to 15 psig (103 kPa).
5.4.5 OIL COOLER
All versions are supplied with four-pass coolers. Either hole can be used for water inlet with no effect on performance. For most applications, 2-5 GPM (7.5-20 L/min) of 60° F (15° C) water is generally sufficient.
Actual water usage will depend on operating conditions. Ideal oil temperature is 140°F (60° C) to 160° F
(72° C).
All standard coolers are designed for use with fresh water only. Do not use brackish or salt water. The liquid to be cooled (oil) flows around the tubes and the cooling liquid (water) flows through the tubes.
WARNING
If the unit is to be located outside or in a building where ambient temperatures can fall below freezing, then care must be taken to ensure the water or liquid used for cooling does not freeze and damage the booster. Oil cooler must be drained of liquid during downtime unless a re-circulating unit using a glycol mixture has been installed.
15
5.5 PIPING CONNECTIONS
WARNING
Pipe loading on the blower should be negligible as pipe loading can cause distortion of the blower. Use proper supports and pipe hangers to assure that there is no loading.
NOTE
Remove the protective covers from the inlet and outlet ports and inspect for dirt and foreign material.
NOTE
If the blower is to be located outdoors or in a building where the temperature surrounding the blower or the water supply and return piping can fall below
35°F (2°C), then care must be taken to ensure that the water (or other cooling liquid) does not freeze and cause damage. Heat exchanger and cooling lines must be drained of liquid during downtime unless a recirculating unit using a glycol mixture has been installed.
NOTE
Units are never shipped from the manufacturer with liquid in the heat exchanger or cooling lines.
Inlet and outlet connections on all blowers are large enough to handle maximum volume with minimum friction loss. Maintain same diameter piping. Silencers must not be supported by the blower. Stress loads and bending moments must be avoided.
Be certain all piping is clean internally before connecting to the blower. We recommend placing a 16-mesh wire screen backed with hardware cloth at or near the inlet connections for the first 50 hours of use until the system is clean. Make provisions to clean the screen after a few hours of operation and completely discard it once the system is clean, as it will eventually deteriorate and small pieces going into the blower can cause serious damage. A horizontal or vertical air flow piping configuration is easily achieved by rearranging the mounting feet position.
HAZARDS ASSOCIATED WITH HAZARDOUS PROCESS FLUIDS
DANGER
It shall be the responsibility of the installer to ensure that piping is adequate, sealing between pipe joints is adequate for the process fluids and proper process and pressure protection devices are in place. It is also the responsibility of the installer to assure that process gasses are not vented in a manner that would be hazardous.
Refer to the manufacturer of the process media to assure that proper safety precautions are in place.
5.5.1 BLOCKAGE OR RESTRICTION
WARNING
Damage to the blower could occur if there is blockage in the inlet or outlet ports or piping. Care should be taken when installing the blower to assure that there are no foreign objects or restrictions in the ports or piping.
16
5.6 MOTOR DRIVES
Two drive connections commonly used are direct drive and V-belt drive.
5.6.1 DIRECT COUPLED
When installing the motor directly to the blower, align shafts to coupling in accordance with the coupling manufacturer’s instructions. Blowers shipped with motor directly coupled and mounted on a common base have been aligned prior to shipment and normally no further alignment is necessary. However, alignment should be checked and adjustments made if necessary prior to starting the unit.
Coupling halves must correctly fit the blower and drive shafts so that only light tapping is required to install each half. The two shafts must be accurately aligned, A direct coupled blower and motor must be aligned with the two shafts not having more than .005” (13 mm) T.I.R. (Total Indicator Reading). Face must be aligned within .002”(.05 mm) .
Proper gap between coupling halves must be established according to coupling manufacturers instructions with the motor armature. This will minimize the change for end thrust on the blower shaft. All direct coupled base mounted units must be re-aligned and greased after field installation.
5.6.2 V-BELTS
If the motor and blower are V-belt connected, the sheaves on both motor and blower shafts, should be as close to the shaft bearings as possible. Blower Sheave is not more than 1/4” (6.5 mm) from the blower drive end cover. The drive sheave is as close to the driver bearing as possible. Care should be taken when installing sheaves on the blower and motor shafts. The face of the should be accurately in line to minimize belt wear.
Adjust the belt tension to the to the manufactures specifications using a belt tension tester. New belts should be checked for proper tension after 24 hours of run time. When manufacturer data is not available industry guidelines are 1/64 inch deflection for each inch of span at 8 to 10 pounds of force in the center of the belt.
Insufficient tensioning is often indicated by slipping (squealing) at start up. Belt dressing should not be used on V-belts. Sheaves and V-belts should remain free of oil and grease. Tension should be removed from belts if the drive is to be inactive for an extended period of time. For more specific information consult the drive manufacturer. In a v-belt drive, the blower sheave must fit its shaft accurately, run true, and be mounted as close to the bearing housing as possible to minimize bearing loads.
A tight or driving fit will force the drive shaft out of its normal position and cause internal damage. A loose fit will result in shaft damage or breaking. The motor sheave must also fit correctly and be properly aligned with the blower sheave.
Adjust motor position on its sliding base so that belt tension is in accordance with drive manufacturer’s instructions. Avoid excessive belt tension at all times. Recheck tension after the first ten hours of operation and periodically thereafter to avoid slippage and loss of blower speed.
Check blower after installation and before applying power by rotating the drive shaft by hand. If it does not rotate freely, look for uneven mounting, piping strain, excessive belt tension, or coupling misalignment.
Check blower at this time to insure oil was added to the reservoirs.
17
SETTING V-BELT TENSION
Proper belt tension is essential to long blower life. The following diagrams and procedures are provided to aid in field adjusting V-belts (when blower is so equipped) for maximum performance.
A visual inspection of the V-belt drive should yield the appearance shown in Figure 7.
Too Tight
Too Tight
Factors outside the control of the belt tensioning system used on an individual blower package assembly may contribute to decreased belt life, such as environmental factors, and quality of the belts installed. This can cause wear of the belts beyond the ability of the tensioning system to compensate.
As such, it is recommended to check belt tension monthly and make any manual adjustments found necessary.

5.7 MOTOR AND ELECTRICAL CONNECTIONS
WARNING
The motor and connections shall be protected to assure that product and environmental condensation does not come in contact with the electrical connections.
NOTE
It is the responsibility of the installer to assure that the motor is in compliance with the latest edition of IEC 60204-1 and all electrical connections performed per IEC 60204-1, this includes over current protection.
Wire the motor and other electrical devices such as solenoid valves and temperature switch to the proper voltage and amperage as indicated on the nameplate of each component being wired. Turn the blower by hand after wiring is completed to determine that there are no obstructions and if the blower turns freely; then momentarily start the blower to check the direction of rotation. Figure 2 shows direction of air flow in relation to rotor rotation. The air flow direction can be reversed by reversing the appropriate motor leads.

6. OPERATION
6.1 GENERAL
DANGER
The blower is not intended to be used with explosive products or in explosive environments. The blower is not intended to be used in applications that include hazardous and toxic gases. Consult the factory for support.
WARNING
Do not operate without guards in place.
WARNING
Maximum operating speed: Table 2 states the maximum operating speed in
RPM (rotations per minute), the maximum pressure differential, maximum vacuum and maximum temperature rise. Do not exceed these limits.
Before starting the blower for the first time under power, recheck the installation thoroughly to reduce the likelihood of troubles. Use the following check list as a guide, but also consider any other special conditions in your installation.
1. Be certain no bolts, rags, or dirt have been left in blower.
2. Be certain that inlet piping is free of debris. If an open outdoor air intake is used, be sure the opening is clean and protected by an inlet filter. This also applies to indoor use.
3. If installation is not recent, check blower leveling, drive alignment, belt tension, and tightness of all mounting bolts.
4. Be certain the proper volume of oil is in the oil reservoir chambers.
5. Be certain the driving motor is properly lubricated, and that it is connected through suitable electrical overload devices.
6. With electrical power off and locked out to prevent accidental starting, rotate blower shaft several times by hand to make sure blower is rotating freely. Unevenness or tight spots is an indication of a problem that should be corrected before progressing.
7. Check motor rotation by momentarily pushing the start button and check flow direction of the blower.
Reverse the motor connections if flow is in the wrong direction.
Initial operation should be carried out under “no load” conditions by opening all valves and venting the discharge to atmosphere, if possible. Then start motor briefly, listen for unusual noises, and check that the blower coasts freely to a stop. If no problem appears, repeat this check, and let the motor run a little longer.
If any questions exist, investigate before proceeding further.
Assuming all tests are satisfactory, the blower will now be ready for continuous full load operation. During the first several days, make periodic checks to determine that all conditions remain acceptable and steady.
These checks may be particularly important if the blower is part of a process system where conditions may vary. At the first opportunity, stop the blower and clean or remove inlet filter. Also, recheck leveling, coupling alignment or belt tension, and mountlng bolts for tightness.
20
6.2 START-UP CHECKLIST
We recommend that these startup procedures be followed in sequence and checked off ( ) in the boxes provided in any of the following cases:
• During initial installation
• After any shutdown period
• After maintenance work has been performed
• After blower has been moved to a new location
DATES CHECKED:
Check the unit for proper lubrication. Proper oil level cannot be over-emphasized.
Refer to the Lubrication section. Please see Recommended Lubricants for information on acceptable lubricants for your product.
Check V-belt drive for proper belt alignment and tension.
Carefully turn the rotors by hand to be certain they do not bind.
WARNING
Disconnect power. Make certain power is off and locked out before touching any rotating element of the blower, motor, or drive components.
“Bump” the unit with the motor to check rotation (counter-clockwise [CCW] when facing shaft) and to be certain it turns freely and smoothly.
Start the unit and operate it for 30 minutes at no load. During this time, feel the cylinder for hot spots. If minor hot spots occur, refer to the Troubleshooting chart.
Apply the load and observe the operation of the unit for one hour.
If minor malfunctions occur, discontinue operation and refer to the Troubleshooting chart.
6.3 OPERATING
The upper temperature limit for blower operation is 400° F (205° C) measured in the exhaust gas stream with a low mass thermocouple. When this temperature limit switch is installed, as the temperature exceeds the predetermined temperature, the blower motor will stop and cannot be restarted until the temperature drops below the trip setting of the temperature switch.
DANGER
The blower is not intended to be used with explosive products or in explosive environments. The blower is not intended to be used in applications that include hazardous and toxic gases. Consult the factory for support.
WARNING
Physical harm may occur if human body parts are in contact or exposed to the process vacuum. Assure that all connections are protected from human contact.
WARNING
If rated vacuum or pressure levels are exceeded, process fluids will migrate to other parts of the blower and system.
21
WARNING
The blower can generate excessive noise, hearing protection is required while the unit is in operation.
CAUTION
Do not touch hot surfaces.
The upper limit of the blower operation is operation.
400 º F ( 205 º C). Do not touch the blower while it is in operation and assure blower is cool when not in
CAUTION
Use of a thermowell insulates the thermocouple. Invalid and delayed readings will result. This can result in ineffective protection devices.
NOTE
The upper temperature limits are not intended for continuous operation.
Consult with factory for detailed information assistance.
6.4 STOPPING
CAUTION
Do not stop the blower if there are high outlet pressures in the outlet piping.
Unload the outlet piping prior to shutting down the blower.
Stop the blower by turning off the motor. Isolate the blower from the vacuum system and vent the blower to atmosphere. Turn off the cooling water, if water cooled. Stop the backing pump. Refer to component instruction manual.
6.5 WATER INJECTED BLOWERS
Water injected into the inlet of a blower operating on vacuum service will cool the blower. The water absorbs the heat of compression as it passes through the unit along with the air/gas being compressed. A blower cooled in this manner can operate safely at higher vacuums or higher inlet temperatures than a normally uncooled unit.
The amount of water required depends on the inlet air/gas temperature, inlet vacuum, water temperature, and the maximum discharge temperature desired. Check with the factory or sales representative for additional guidance.
6.5.1 OPERATION
1. Check oil level in sight glass of blower and assure all fittings are tight.
2. Check the water injection system to assure water is available.
3. Operate the blower dry for a few minutes at no load to check correct rotation and smooth operation.
4. Turn water on and adjust flow as recommended for the individual blower. Assure water discharges freely from the outlet piping.
5. Apply vacuum and observe operation at the desired inlet condition.
22
6.5.2 SHUTDOWN
1. The blower can be shutdown for brief periods by relieving the inlet vacuum, shutting the water off, and then stopping the unit.
2. Rusting during a slightly longer shutdown period can be avoided by operating the blower under a partial vacuum without the water injection, allowing the blower to heat within safe limits. The heat will tend to drive off residual moisture.
3. For extended shutdown, oil may be injected into the inlet of the heated blower just prior to shutting the blower down. The oil will provide a protective coating on the internals. Insure that the water is completely shut off after shutdown.
4. Special coatings or platings are available to minimize rusting or corrosion in applications where units can remain wet.
Vertical flow units with two-lobed, plugged rotors should always be used. Always orient system such that the blower intake is at the top and discharge at the bottom.
CAUTION
Water injection can cause lime build-up on rotors. Check water supply for hardness. The use of water softeners, other chemicals, or distilled water may be necessary to prevent or remove this build-up. However, due to the wide variations in mineral content, pH, and chemical content of water that can be injected, Tuthill Vacuum & Blower Systems cannot be responsible for damage which may result should this build-up occur. Units should be inspected regularly to determine any problems.
NOTE
For liquid injection other than water, consult the factory.
6.6 RECOMMENDED SHUTDOWN PROCEDURE TO MINIMIZE RISK OF FREEZING OR
CORROSION
When high humidity or moisture is present in an air piping system, condensation of water can occur after the blower is shut down and the blower begins to cool. This creates an environment favorable to corrosion of the iron internal surfaces, or in cold weather, the formation of ice. Either of these conditions can close the operating clearances, causing the blower to fail upon future start-up.
The following shutdown procedure outlined below minimizes the risk of moisture condensation, corrosion and freezing.
NOTE
Care must be taken so as not to overload or overheat the blower during this procedure.
1. Isolate the blower from the moist system piping, allowing the blower to intake atmospheric air. Operate the blower under a slight load allowing the blower to heat within safe limits. The heat generated by the blower will quickly evaporate residual moisture.
2. For carpet cleaning applications, after the work is completed, simply allow the blower to run a few (3-5) minutes with the suction hose and wand attached. The suction hose and wand will provide enough load to the blower to evaporate the moisture quickly.
23
3. For extended shutdown, inject a small amount of a light lubricating oil such as 3-in-One ® or a spray lubricant such as WD-40 ® into the inlet of the blower just prior to shutdown. (3-in-One and WD-40 are registered trademarks of WD-40 Company.) The lubricant will provide an excellent protective coating on the internal surfaces. If using a spray lubricant, exercise care to prevent the applicator tube from getting sucked into the blower. The applicator tube will damage the blower, most likely to the point that repair would be required.
4. If the blower is being taken out of commission for an extended period of time, please also refer to the
“Long Term Storage” section of this manual.
7. MAINTENANCE
7.1 GENERAL
Regular inspection of your blower and its installation, along with complete checks on operating conditions will pay dividends in added life and usefulness. Also, service the drive per manufacturer’s instructions and lubricate the coupling or check belt drive tension. By use of thermometers and gauges, make sure that blower operating temperature and pressure remain within allowed limits.
DANGER
The blower and parts may contain hazardous media. Assure that pump and parts are evacuated of hazardous media prior to servicing.
CAUTION
The electrical service must be isolated and de-energized prior to maintenance. Apply appropriate procedures to assure electrical supply is de-energized and cannot be inadvertently energized during maintenance.
Assure piping and product is isolated prior to maintenance of blower. Apply appropriate procedures to assure piping and product is isolated and that inadvertent opening of valves cannot occur during maintenance.
CAUTION
During routine maintenance, inspect and assure that guards are in place and secure.
Particular attention should be paid to lubrication of timing gears and bearings in accordance with comments under the Lubrication section.
When a blower is taken out of service, it may require internal protection against rusting or corrosion. The need for such protection must be a matter of judgment based on existing conditions as well as length of down time. Under atmospheric conditions producing rapid corrosion, the blower should be protected immediately. Refer to the Long Term Storage section for more details.
24
7.2 REGULAR MAINTENANCE
A good maintenance program will add years of service to your blower.
A newly installed blower should be checked frequently during the first month of operation, especially lubrication. With blower at rest, check oil level in both the gear (drive) end and free (non-drive) end of the blower and add oil as needed. Complete oil changes are recommended every 1000-1200 operating hours, or more frequently depending on the type of oil and operating temperature. Also change the oil more frequently if pumping corrosive vapors or where excessive operating temperatures are encountered. The following is recommended as a minimum maintenance program.
DAILY
1. Check and maintain oil level, and add oil as necessary.
2. Check for unusual noise or vibration (See Troubleshooting )
WEEKLY
1. Clean all air filters. A clogged air filter can seriously affect the efficiency of the blower and cause overheating and oil usage.
2. Check relief valve to assure it is operating properly.
MONTHLY
1. Inspect the entire system for leaks.
2. Inspect condition of oil and change if necessary.
3. Check drive belt tension and tighten if necessary.
NOTE
Oil levels should be checked every 24 hours of operation.
Proper oil drain schedules require oil be changed before the contaminant load becomes so great that the lubricating function of the oil is impaired or heavy disposition of suspended contaminants occurs. To check the condition of the oil, drain a sampling into a clean container and check for the presence of water or solids.
Slight discoloration of the oil should not necessitate an oil change.
7.3 SPARE PARTS
Should adjustments or replacement eventually be needed, these can often be performed locally as described in this book after obtaining required parts. Personnel should have a good background of mechanical experience and be thoroughly familiar with the procedures outlined in this manual. Major repairs not covered in this book should be referred to the nearest Tuthill Vacuum & Blower Systems service representative.

Springfield, MO 65803-8702
NOTE
Current regulations require Material Safety Data Sheet to be completed and forwarded to Tuthill Corporation on any unit being returned for any reason which has been handling or involved with hazardous gases or materials.
This is for the protection of the employees of Tuthill Corporation who are required to perform service on this equipment. Failure to do so will result in service delays.
NOTE
When returning a blower to the factory for repair, under warranty, please note the factory will not accept any unit that arrives without authorization.
Contact the Service Department for return authorization.
7.5 LONG TERM STORAGE
Any time the blower will be stored for an extended period of time, you should take make sure that it is protected from corrosion by following these steps:
1. Spray the interior (lobes, housing and end plates) with rust preventative. This should be repeated as conditions dictate and at least on a yearly basis.
2. Fill both end covers completely full of oil.
3. Firmly attach a very prominent tag stating that the end covers are full of oil and must be drained and refilled to proper levels prior to startup.
4. Apply a rust preventative grease to the drive shaft.
5. Spray all exposed surfaces, including the inlet and discharge flanges, with rust preventative.
6. Seal inlet, discharge and vent openings. It is not recommended that the unit be set in place, piped to the system, and allowed to remain idle for a prolonged amount of time. If any component is left open to the atmosphere, the rust preventative will escape and lose its effectiveness.
7. During storage, ensure that the blower does not experience excessive vibration.
8. Attach a desiccant bag to either of the covers to prevent condensation from occurring inside the blower.
Make sure any desiccant bag (or bags) is so attached to the covers that they will be removed before startup of the blower.
9. Store the blower in an air conditioned and heated building if at all possible. At least insure as dry conditions as possible.
10. If possible, rotate the drive shaft by hand at least monthly in order to prevent seals from setting in one position.

8. DISASSEMBLY AND REASSEMBLY
8.1 DISASSEMBLY OF BLOWER
1. Drain lubrication from either end and disconnect all external oil lines. Do not attempt to remove oil distribution line bushing in the non-drive end plate until the end cover has been removed and the internal fittings are disconnected. The oil filter and heat exchanger may be removed or left fastened to the cover. Mark piping and other parts so that they can go back in their original position when reassembling.
8.1.1 FREE END DISASSEMBLY
2. Support free end cover (7) using a lifting strap. Remove cap screws (26) and install two of them as jacking screws in the tapped holes next to the dowel pins. It is recommended that two studs 8” (203 mm) long be used to assist in supporting the cover until it has cleared the dowel pins. It is not necessary to remove oil pump (144) and the adapter plate (313) from the cover unless these items are being replaced.
3. Remove large O-ring (302), four slinger cap screws (309) (5/16-12 point socket required), and oil slinger (20). Tap drive shaft (310) lightly with a mallet to remove from rotor shaft. Remove cap screws
(30) and the oil retaining rings (15).
8.1.2 GEAR END DISASSEMBLY
4. Remove drive shaft key (23). Remove all burrs and other defacements from the drive shaft.

Series 66/69: Remove cap screws (30 & 93). Remove seal housing (91) and remove stator portion of the mechanical seal (76B). Using a spanner wrench, remove the adapter sleeve (87) by turning counter clockwise. Remove mating ring (76A) and O-rings (88 & 140).
5. Support drive end cover (6) as done on the non drive end. Remove cap screws (26). The drive end cover also has jacking screw holes, but it must slide off the spherical roller bearing on the drive shaft.
To keep the bearing outer race from cocking, it is suggested that the drive shaft bearing pressing tool shown on page 35 be used.
6. Remove cap screws (66) and drive shaft (45). The bearing (50) should be pulled now unless it is to be pressed apart after the drive shaft has been removed.
7. Stand the blower up on the non drive end on 6” × 6” (152 × 152 mm) blocks remove cap screws (326) from the driven gear and align the match marks on the timing gear teeth (8). Using a suitable puller or extended pry bar, remove the gear shell from their hubs. The shell and hub are matched, do not interchange. Remark if the original markings are no longer visible.
8. Unlock spanner nut lockwashers (36) and remove spanner nut (35) and lockwashers. Remove gear hubs with puller. Remove gear keys (24).
9. Remove oil sight gauge (70). Remove cap screws (307) and mounting feet (304), Series 66 & 69 have feet (304) and (408). All feet are mounted on 1 1/8” (28.7 mm) hollow locating dowels (306) from which they should easily disengage by tapping lightly with a mallet. Discard O-rings (305).
10. Remove cap screws (30) bearing retainer rings (14) and end plate cap screws.
8.1.3 END PLATE AND ROTOR DISASSEMBLY
11. The end plate, with the bearings, must be pulled from the rotor shafts. Make up two Bearing Pressing
Fixture plates shown on page 36 along with eight pieces of 1/2 × 13 all thread, flat washers, and hex nuts. The use of a hydraulic ram is also recommended but some modifications may be necessary depending on the type of equipment available. Install each plate to the bearing retainer ring mounting holes and apply pressure equally to the ends of the rotor shaft by tightening the nuts on the threaded rods. Install spacers under plate after rotor shafts become flush with top of bearing. Use a hoist to pick up the end plate once the bearings have cleared the shaft.
27
12. After the end plate is removed, tap out the bearings (9). Remove large O-ring (176).
Series 19/86: Tap out lip seals (12).
Series 55/82/66/69: Pull out by hand the stator portion on the mechanical seal (54). Retain the seal adapter (74) for reassembly.
NOTE
If the rotor shaft sleeves (239) were removed with the end plate, pull them out by hand on the 19/86 series. On the other series you must drive them out with the bearings. To avoid damage to the sleeves do not use any hard faced hammers or steel punches to drive the sleeves out. Separate the mating rings from the sleeves.
13. To replace the PTFE washers of the labyrinth seals, remove the retaining ring (219), two wave springs
(282), steel spacers (281), and PTFE washers (280).
NOTE
Older units will contain six PTFE and seven steel washers in each bore. The current PTFE washers are thicker, therefore you will only use five PTFE and six steel washers when reassembling.
14. Reinstall the end plate without the bearings and seals and secure with six cap screws equally spaced.
Turn the unit over and support with block under the gear end plate.
15. Repeat steps 8,11,12 and 13 to remove non-drive end plate.
NOTE
Do not damage bearing spacer (123) when removing bearings. This spacer is only used on the free end.
16. Lift the rotors (1) out of the housing (3). Unbolt the gear end plate and lift the housing off. Clean all parts and Inspect for wear. It is not necessary to remove the oil distribution fittings on the end plates and the gear cover but they should be checked with compressed air to be sure the five orifices are not clogged.
8.2 ASSEMBLY
The assembly procedure is generally the same for all series, but where there are differences, notations will be made. All joints between housing, end plate, and covers are O-ring sealed. An RTV silicone sealer or equal is used on the lip seals and mounting feet.
Dowel pins are used to locate end plate, housing, and covers in the proper location relative to each other. It is recommended that the gear end rotor shaft bearings along with all other replacement parts be purchased from Tuthill Vacuum & Blower Systems, to insure the rotor location is correct with the proper end clearance relative to the gear end plate.
8.2.1 PREPARATION OF END PLATES
1. Make sure all parts are and free of any nicks or burrs caused by disassembly. See page 36 for dimensions of the seal installation tools.
2. Position end plate with bearing bores up (flange side down) and install components of the labyrinth seals. Starting with a PTFE washer (200) alternately stack five PTFE and five steel spacers in each bore. Add two wave springs, one more steel spacer and a retaining ring. Compress to seat seal.
28
NOTE
NOTE: Two wave springs are necessary for the proper pressure on the seal, but because of the pressure a tool as shown on page 23 is needed to press the retainer ring into its groove. The tool will center the labyrinth seal as it presses the retainer ring in place.
3. Series 19/86: Apply sealer to the O.D. of the lip seal. Install with lip facing upward. Tap in place with installation tool shown on page 36. Apply grease to lip of seal.
Series 55/82/66/69: Install seal adapter (74). The adapter is used to anchor the stator portion of the mechanical seal (54). To install the seal, grease both the O-ring and seal bore, then push the seal, by hand, into the bore and against the seal adapter, making sure the two dimples on the bottom of the seal case are aligned with the holes in the seal adapter. Clean surface with soft tissue and acetone.
NOTE
Never drive mechanical seal or seal tool with any type of hammer. This could result in damage to the carbon or its ability to properly seal.
8.2.2 GEAR END ASSEMBLY
4. Place non-drive end plate on 6” × 6” blocks with the solid side up. The end plate must be blocked up so rotor shafts will not touch floor when they are installed.
Grease and install O-ring (176) in end plate groove.
Install housing (3) making sure dowel pins are in place. Do not bolt in place at this time.
5. Lay two pieces of steel approximately 2” × 2” × 1/8” thick at the bottom of the housing as shown in Figure
DRIVE
DRIVEN
9 with the end (long shafts) up. The rotor lobes will be above the end of the housing which is necessary when assembling this end.
6. Grease and install O-ring (176) in groove of gear end
Figure 9 - Rotors in Housing plate. Use sufficient grease to hold it into place when the end plate is turned over.
7. Install the end plate on the rotors and housing. The end plate will rest on the ends of the rotor lobes, and there will be a space between the housing and the plate. Install all cap screws (301) and tighten end plate to housing until tight.
8. Use six cap screws (301) equally spaced and secure non drive end plate against shims at bottom end of rotors. Do not torque these bolts.
9. Grease O-ring (331) and start onto rotor shaft.
Series 19/86: Start sleeve (239) over shaft (larger diameter down) while forcing O-ring into step at the bottom of the sleeve. Slide sleeve down the shaft until seated. You may encounter interference as the sleeve passes through the PTFE rings. Tap sleeve with mallet to seat if necessary.
Series 55/82/66/69: Grease internal O-ring of mating ring portion of seal (Assemble mating ring over sleeve (236) with lapped surface down. Slot in mating ring must line up with pin in sleeve and be flush with top of sleeve when properly installed. Clean lapped surface of mating ring with soft tissue and acetone. Lubricate surface and start sleeve over rotor shaft while forcing O-ring into step at bottom of sleeve. Carefully slide this assembly down the shaft until seated.
10. Coat the rotor shaft with an anti-seize lubricant and press the bearing (9) on the shaft. The bearing manufacturer numbers and/or an acid dot (inner race) should be up or toward the gears. Use the same plates used to disassembly and a sleeve to press on the inner race of the bearing when installing.
11. Loosen cap screws holding non-drive end plate to housing then install bearing retainer rings (14) and secure with cap screws (30). At this time check clearances between the rotor lobes and gear end plate.
See page 34 for the correct gear end clearances. If clearances are not within specifications, recheck parts to find cause of improper clearances before proceeding. Retighten the cap screws on the nondrive end but do not torque at this time.
29
12. Install keys (24) into rotor shafts. Tight fit required. Coat shafts and key with anti-seize. If new gears are being installed, disassembly gear shell from hub.
13. Heat the gear hubs to 350° F (177° C) At this temperature they should fit easily to the rotor shafts.
NOTE
After heating, handle gear hubs with insulated gloves only.
Secure with lockwashers (36) and locknut (35) immediately after hub is installed. Torque to proper specification. Do not install gear shell until hub has been allowed to cool.
8.2.3 FREE END ASSEMBLY
14. Turn assembly over and support on blocks. Remove the six cap screws and put jack screws in the holes provided in the flange of the end plate and remove plate. Take out two shims and check free end clearance between end of the lobes and housing using a flat bar and feeler gauges or a depth micrometer. See page 34 for correct clearances.
Series 19/86: Repeat step 9 to install sleeves.
15. Series 55/82/66/69: Recheck carbon of seal to be sure it is clean.
All series: Reinstall end plate making sure O-ring is still in its groove and secure with all the cap screws (26).
16. Series 55/82/66/69: Repeat step 9 install sleeve and mating ring assemblies.
17. Install bearing spacers (123) then repeat step 10 to install bearings. Secure with lockwashers and locknuts (936 & 35). Bend one lockwasher tap into spanner nut slot to lock all nuts).
18. Install oil retainer rings (15) and cap screws (30) (only six required).
19. To install mounting feet (304) or (304 & 408 on 66/69 series) the hollow dowel (306) should be in the foot. If any of the dowels are in the end plate, remove and transfer to the feet. Grease and install the
O-ring over dowel. Run a bead of silicone sealer 1/4” wide, around the dowel holes on the foot mounting pad of the end plate. This acts as a backup O-ring to prevent any oil leakage. Secure with cap screw
(307). Reconnect oil pipes then stand unit on its feet.
20. The gear hub should now be cool enough to assemble the gear shells. The dowel pins should be in the hub. Transfer if necessary. Reinstall the timing shim and assemble the shells to their proper hubs (align hubs and shell match marks). Install drive gear first (right hand helix) the align the match marks on the teeth and assemble driven gear (left hand helix).
NOTE
The six cap screws that were in the drive gear are too long without the drive shaft. Temporarily use the six cap screws from the driven gear. Use three in each gear (every other hole).
30
8.2.4 ADJUSTING INTERLOBE CLEARANCE
21. The timing gears are made up of two pieces. The outer gear shells are fastened to the inner hubs with six cap screws and located with two dowel pins.
By adding shims between a gear shell and the inner hub the gear is moved axially relative to the inner hub which is mounted on the rotor shaft. Being a helical gear, it rotates as it is moved out and the rotor turns changing the clearances between rotor lobes. Adding .012” (.30 mm) shim thickness will change the rotor lobe clearance by .003” (.076 mm).
The timing shim is formed from a number of .003 (.075 mm) shims, which

EXAMPLE: If AA reading is .030” (.76 mm) and BB reading is .022” (.56 mm), by removing .016” (.40 mm) shim, the readings will change one-quarter of this amount or .004” (.10 mm). AA reading will drop to .026” (.66 mm) and BB reading will increase to .026” (.66 mm).
To determine the amount of shim to add or remove from the driven gear, simply subtract the two readings .030” (.76 mm - .022” (55 mm) = .008” (.21 mm) and double the result .008 (.21 mm) × 2 =
.016 (.42 mm).
22. To determine whether to add or remove this amount the following rule will always apply: If the right reading (AA) is greater than the left side reading (BB), remove this amount.
If the right side reading (AA) is greater than the left side reading (BB), remove this amount. If the right side reading (AA) is less than the left side reading (BB), then add this amount.
NOTE
If the results require you to remove shim from the driven gear and there are no shims left under this gear, go to the drive gear and add this amount for the same result. When removing or replacing a gear for shimming the timing mark should be matched and on center. Either gear may be pulled in this position.

8.2.5 COMPLETING GEAR END ASSEMBLY
23. Press drive shaft bearing (50) on drive shaft (45). Remove the three cap screws from drive gear and install in the drive gear. Clean and remove all burrs from mating surfaces of the gear and drive shaft flange. Install with cap screws (66).
Torque gear cap screws at this time. Check drive shaft run out at the seal journal. Do not exceed
.003” T.I.R. (.13 mm)
Series 19/86/55/82: Secure bearing with Lockwasher (320) and locknut (319). Bend over tab to lock in place.
24. Grease and install O-ring (302). To aid in the installation of the gear cover (6) a tool as shown on page
36 should be made to hold the outer race of the bearing square with the shaft. Side the cover over the tool and secure with cap screws (26).
25. Series 19/86/55/82: Press lip seal (13) into adapter plate (46) with lip facing inward. Grease lip, install O-ring (314) then carefully install assembly over drive shaft.

Clean mating ring (76A) with soft tissue and acetone and install on adapter while aligning pin (300) with slot in mating ring. The larger surface area of the mating ring face inward. Install retaining ring (78), using spanner wrench. Tighten set screws (90).
Lubricate seal O-ring and hand press seal (76B) into the seal housing (91) making sure to align the two dimples on the bottom of the seal with corresponding holes in the seal housing. Clean carbon surface with soft tissue and acetone. Grease and install O-ring (314) around the seal bore. Place a few drops of lubricating oil on the mating ring, then carefully install assembly over the drive shaft on to the cover. Secure with cap screws (30 & 93).
8.2.6 COMPLETING FREE END ASSEMBLY
26. Grease and install O-ring (302) in end plate groove. Install oil pump drive shaft (310) and oil slinger (20) on rotor shaft and secure with cap screws (309).
27. Align drive shaft slot with oil pump tang and carefully slide cover over shaft and onto dowel pins in end plate. Tap cover gently until contact with O-ring is made. If gap remains recheck slot and tang alignment for proper engagement. Secure cover with cap screws (26).
NOTE
If oil pump assembly (144) is being replaced, install cover first, then install
O-ring (325) and oil pump.
28. Complete assembly by reinstalling or connecting all remaining oil lines, sight glass, etc. Oil filter element should always be replaced with factory filter when overhauling a unit. Fill with lubricant to proper level on column sight glass.
