FILTER - ENGINE OIL
REMOVAL
1. Clean the area around the oil filter head. Remove the filter from below using a cap-style filter wrench.
2. Clean the gasket surface of the filter head. The filter canister O-Ring seal can stick on the filter head. Make sure
it is removed.
INSTALLATION
1. Fill the oil filter element with clean oil before installation. Use the same type oil that will be used in the engine.
2. Apply a light film of lubricating oil to the sealing surface before installing the filter.
CAUTION: Mechanical over-tightening may distort the threads or damage the filter element seal.
3. Install the filter until it contacts the sealing surface of the oil filter adapter. Tighten filter an additional
1⁄2turn.

from the bore.
NOTE: If the plunger is stuck in the bore, it will be
necessary to remove the filter head.
CLEANING
1. Clean the regulator spring and plunger with a suitable solvent and blow dry with compressed air. If the plunger
bore requires cleaning, it is necessaryto remove the oil filter head to avoid getting debris into the engine.

PUMP - ENGINE OIL
REMOVAL
1. Disconnect the battery negative cables.
2. Remove fan/drive assembly (Refer to 7 - COOL-
ING/ENGINE/RADIATOR FAN - REMOVAL).
3. Remove the accessory drive belt (Refer to 7 -
COOLING/ACCESSORY DRIVE/DRIVE BELTS -
REMOVAL).

8. Remove the gear housing cover (Refer to 9 -
ENGINE/VALVE TIMING/GEAR HOUSING COVER
- REMOVAL).
9. Remove the four mounting bolts (2) and pull the oil pump (1) from the bore in the cylinder block.
CLEANING
Clean all parts in solvent and dry with compressed air. Clean the old sealerresidue from the back of the gear
housing cover and front of the gear housing.
INSPECTION
Disassemble and inspect the oil pump as follows:
1. Visually inspect the lube pump gears for chips,
cracks or excessive wear.
2. Remove the back plate (1).
3. Mark TOP on the gerotor planetary (3) using a felt
tip pen.
4. Remove the gerotor planetary (3) inspect for
excessive wear or damage. Inspect the pump
housing and gerotor drive (2) for damaged and
excessive wear.
5. Install the gerotor planetary in the original position.
6. Measure the tip clearance (1). Maximum clearance
is 0.1778 mm (0.007 inch). If the oil pump is out of
limits, replace the pump.

7. Measure the clearance of the gerotor drive/gerotor
planetary (2)to port plate (1). Maximum clearance
is 0.127 mm (0.005 inch). If the oil pump is out of
limits, replace the pump.
8. Measure the clearance of the gerotor planetary to
the body bore (1). Maximum clearance is 0.381
mm (0.015 inch). If the oil pump is out of limits,
replace the pump.
9. Measure the gears backlash (3,4). The limits of a
used pump is 0.15- 0.25 mm (0.006-0.010 inch). If
the backlash is out of limits, replace the oil pump.
10. Install the back plate.
INSTALLATION
1. Lubricate the pump withclean engine oil. Filling the
pump with clean engine oil during installation will
help to prime the pump at engine start up.
2. Install the pump. Verify the idler gear pin is
installed in the locating bore in the cylinder block.
Tighten the oil pump mounting bolts in two steps, in
the sequence shown in.
Step 1—Tighten to 8 Nꞏm (71 in. lbs.) torque.
Step 2—Tighten to 24 Nꞏm (18 ft. lbs.) torque.

3. The back plate on the pump seats against the bot-
tom of the bore in the cylinder block. When the
pump is correctly installed, the flange on the pump
will not touch the cylinder block.
4. Measure the idler gear to pump drive gear back-
lash and the idler gear to crankshaft gear backlash.
The backlash should be 0.15- 0.25 mm
(0.006-0.010 inch). If the backlash is out of limits,
replace the oil pump.
5. If the adjoining gear moves when you measure the
backlash, the reading will be incorrect.
6. Apply a bead of Mopar
Silicone Rubber Adhesive Sealant or equivalent to the gear housing cover sealing sur-
face.
7. Install the gear housing cover (Refer to 9 - ENGINE/VALVE TIMING/GEAR HOUSING COVER - INSTALLA-
TION).
