2 How to Replace the Lubricating Oil and Oil Filter

How to Replace the Lubricating Oil and Oil Filter
The oil filter is an integral part of the lubrication system. Proper filter selection and maintenance are important to satisfactory
engine performance and service life. The filter should be used to maintain a clean system, not to clean up a contaminated
system. The maintenance intervals for the appropriate duty cycle are listed in tables in this manual.
Change the oil and replace the lubricating oil filter as follows:
NOTE: If the used oil was contaminated by fuel or coolant, it may be necessary to take the vehicle to a certified
Detroit Service Center. The Service Center may drain the oil and then remove the oil pan, oil pump, and oil pump
intake manifold to drain the remaining oil held back by the backflow valve. It is important to remove all
contaminated oil from the engine.
NOTE: Change the engine oil only when the engine oil temperature is approximately 60°C (140°F). Changing cold
oil will result in extended drain times.
WARNING: PERSONAL INJURY
To avoid injury, never remove any engine component while the engine is running.
1. Place the transmission in neutral, and set the parking brake.
NOTICE: Use care to prevent foreign objects from entering the filter housing.
2. Clean outside of the oil filter housing.
3. Using a 36-mm socket, unscrew the oil filter cap and filter and allow the oil to drain into the housing. After draining is
complete, remove the assembly from the housing.
4. Remove the filter element by pressing and twisting the side and detaching it from the cap.
5. Remove the oil filter O-ring and discard. Lightly coat a new O-ring with clean engine oil and install it on the filter cap.
6. Check the filter housing for any debris and remove if necessary.
7. Insert a new filter element into the oil filter cap.
8. Insert the filter element and cap assembly into the housing. Torque the cap to 40 to 50 N·m (30 to 37 lb·ft).
9. Drain oil from the oil pan as follows:
a. Place a suitable receptacle, 55 L (58 qt) or more, beneath the oil drain plug on the underside of the oil pan.
b. Carefully unscrew the oil drain plug, and allow the oil to drain out.
c. Discard the plug seal ring.
10. Install the oil pan drain plug with a new O-ring and torque the plug:
a. On a plastic oil pan, torque plug to 45 N·m +/- 7 N·m (33 lb·ft +/- 5 lb·ft).
b. On an aluminum oil pan, torque plug to 60 N·m +/- 9 N·m (44 lb·ft +/- 6 lb·ft ).
NOTICE: Do not add oil if the oil reading is between the crosshatch area on the dipstick. There are approximately
5.0 L (5.2 qt) from the fill mark to the full mark. Overfilling the oil pan can cause engine damage.
11. Add new engine oil through the oil fill tube in the following amount; Refer to section "Engine Oil Capacities". Verify
the oil level reading is between the full and fill marks on the dipstick.
WARNING: PERSONAL INJURY
To avoid injury before starting and running the engine, ensure the vehicle is parked on a level
surface, parking brake is set, and the wheels are blocked.

WARNING: ENGINE EXHAUST
To avoid injury from inhaling engine exhaust, always operate the engine in a well-ventilated area.
Engine exhaust is toxic.
NOTICE: If no oil pressure is shown after approximately 10 seconds, stop the engine and determine the cause.
Running the engine with no oil pressure could result in engine damage.
12. Start the engine with the accelerator pedal in the idle position (600 rpm). Monitor the oil pressure gauge or indicator
lamp. Keep the engine running at idling speed (600 rpm) until the oil pressure reading is 10.2 psi (70 kPa) or more for
the DD15/16 and 11.6 psi (80 kPa) or more for the DD13.
NOTICE: Do not add oil if the oil reading is between the crosshatch area on the dipstick. There are approximately
5.0 L (5.2 qt) from the fill mark to the full mark. Overfilling the oil pan can cause engine damage.
NOTE: If the engine operating temperature is below 60°C (140°F), the engine must be on a level surface and then
shut down for 60 minutes for an accurate oil level reading. Otherwise, the engine must be brought up to an
operating temperature of 60°C (140°F), parked on a level surface and then shut down for five minutes for an
accurate oil level reading.
13. Check the filter housing for signs of leakage.
14. Stop the engine. Check the oil level again per the following guidelines. If necessary, add oil no more than 5.0 L (5.2 qt)
at a time up to the maximum fill level on the oil dipstick.

3 Installation of the Oil Pan

Installation of the Oil Pan
Install as follows:
1. If the oil pump was removed, Refer to section "Installation of the Oil Pump, Oil Suction Manifold, and Oil Lines".
2. When a plastic oil pan is used, insert the raised lip portion of the seal into the groove in the oil pan. Press down on the
isolator seal and insert it completely around the oil pan. Be careful not to stretch or bunch the seal. For best results,
install the seal at each corner, then at points half way between the corners. Continue in this manner, halving the
distance and seating the seal.
3. For the aluminum oil pan, place the gasket on the top of the pan.
4. Apply a 5mm diameter bead of Loctite® 5970 or equivalent to the four corners circled below on the gasket.
5. Install the eighteen oil pan bolts and sleeve assemblies through the pan rail into the holes in the gasket.
6. Ensure the joint surfaces of the gear case, the cylinder block, and front cover are cleaned and there is no damage that
could prevent sealing.
7. Install the oil pan assembly in position on the cylinder block.
NOTICE: Before torquing, bolt grade must be determined by a marking on the bolt head. Grade 8.8 oil pan bolts
cannot be torqued above 25 N·m (18 lb·ft) or damage to the bolt will occur.
8. Ensure that the seal has not been disturbed. Torque the eighteen oil pan bolt assemblies to 25 N·m (18 lb·ft), using the
proper sequence shown below.

NOTE: The corner bolts on the oil pan will be torqued twice, as each is marked with two numbers in graphic
above.
9. Install the oil pan drain plug with a new O-ring and torque the plug:
a. On a plastic oil pan, torque plug to 45 N·m +/- 7 N·m (33 lb·ft +/- 5 lb·ft).
b. On an aluminum oil pan torque plug to 60 N·m +/- 9 N·m (44 lb·ft +/- 6 lb·ft).
10. Install bolt at harness P-clip on the front center of the oil pan.
11. Install the dipstick.
12. Install the oil filter and cap. Torque to 55 N·m (40 lb·ft).
13. If oil pump was removed, Refer to section "Installation of the Oil Pump, Oil Suction Manifold, and Oil Lines".
14. Prime the lubrication system. Refer to section "Priming the Engine Lubrication System".
15. Refill the oil pan with lubricating oil. Refer to section "Engine Oil Capacities".
WARNING: PERSONAL INJURY
To avoid injury before starting and running the engine, ensure the vehicle is parked on a level
surface, parking brake is set, and the wheels are blocked.
WARNING: ENGINE EXHAUST
To avoid injury from inhaling engine exhaust, always operate the engine in a well-ventilated area.
Engine exhaust is toxic.
16. Start the engine and inspect for leaks.
