holes and remove the rear seal with a slide hammer
(Fig. 108).
INSTALLATION
CAUTION: The seal lip and the sealing surface on
the crankshaft must be free from all oil residue to
prevent seal leaks. The crankshaft and seal sur-
faces must be completely dry when the seal is
installed. Use a soap and water solution on outside
diameter of seal to ease assembly.

solvent and dry with a clean shop towel or com-
pressed air. Wipe the inside bore of the crankshaft
seal retainer with a clean shop towel.
(2) Inspect the crankshaft journal for gouges,
nicks, or other imperfections. If the seal groove in the
crankshaft is excessively deep, install the new seal
1/8º deeper into the retainer bore, or obtain a crank-shaft wear sleeve that is available in the aftermar-
ket.
(3) Install the seal pilot, provided in the replace-
ment kit, onto the crankshaft.
(4) Using the provided alignment/installation tool,
start the seal over the pilot and into the retainer by
hand.

the 12, 3, 6, and 9 o'clock positions until the align-
ment tool bottoms out on the retainer (Fig. 109).
(6) Remove the seal pilot.
(7) Install the flywheel or converter drive plate.
Tighten the bolts to 137 N´m (101 ft. lbs.) torque.

mended that the crankshaft seal is replaced. Support
the seal retainer and drive out the old seal.
(2) Using the retainer alignment/seal installation
tool provided in the seal service kit, install the align-
ment tool into the retainer and install to the cylinder

exercised when disposing of used engine oil after
it has been drained from a vehicle's engine.
OIL COOLER & LINES
CLEANING AND INSPECTION
Clean the sealing surfaces.
Apply 483 kPa (70 psi) air pressure to the element
to check for leaks. If the element leaks, replace the
element.
OIL FILTER
REMOVAL
(1) Clean the area around the oil filter head.
Remove the filter using a 90-95 mm 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 seal-
ing 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 ó turn.
OIL PAN
REMOVAL
(1) Disconnect the battery negative cables.
(2) Raise vehicle on hoist.
(3) Remove transmission and transfer case (if
equipped).

CAL/STARTING/STARTER MOTOR - REMOVAL)
and transmission adapter plate assembly.
WARNING: HOT OIL CAN CAUSE PERSONAL
INJURY.
(7) Drain the engine oil (Refer to 9 - ENGINE/LU-
BRICATION/OIL - STANDARD PROCEDURE).

ing washer and tighten to 60 N´m (44 ft. lbs.) torque.
(9) Remove oil pan bolts, break the pan to block
seal, and lower pan slightly and remove oil suction
tube fasteners.
(10) Remove oil pan and suction tube (Fig. 151).

OIL (Continued)

CLEANING
Remove all gasket material from the oil pan and
cylinder block sealing surfaces. Extra effort may be
required around T-joint areas. Clean oil pan and
flush suction tube with a suitable solvent.
INSPECTION
Inspect the oil pan, suction tube, and tube braces
for cracks and damage. Replace any defective compo-
nent. Inspect the oil drain plug and drain hole
threads. Inspect the oil pan sealing surface for
straightness. Repair any minor imperfections with a
ball-peen hammer. Do not attempt to repair an oil
pan by welding.
INSTALLATION
(1) Fill the T-joint between the pan rail/gear hous-
ing and pan rail/rear seal retainer with sealant. Use
MopartSilicone Rubber Adhesive Sealant or equiva-
lent.
(2) Place suction tube in oil pan and guide them
into place (Fig. 151). Using a new tube to oil pump
gasket, install and tighten the suction tube bolts by
hand. Starting with the oil pump inlet bolts, tighten
the bolts to 24 N´m (18 ft. lbs.) torque. Tighten the
remaining tube brace bolts to 24 N´m (18 ft. lbs.)
torque.
(3) Starting in the center and working outward,
tighten the oil pan bolts to 24 N´m (18 ft. lbs.)
torque.
(4) Install the flywheel housing assembly with the
starter motor attached and tighten bolts to 60 N´m
(44 ft. lbs.) torque.
(5) Connect starter motor cables.
(6) Install transmission and transfer case (if
equipped).
(7) Lower vehicle.
(8) Install battery negative cables.
(9) Fill the crankcase with new engine oil.
(10) Start engine and check for leaks. Stop engine,
check oil level, and adjust, if necessary.
OIL PRESSURE RELIEF VALVE
REMOVAL
(1) Disconnect the battery negative cables.
(2) Remove the threaded plug, spring and plunger
(Fig. 152). Insert a finger or a seal pick to lift the
plunger 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 necessary to
remove the oil filter head to avoid getting debris into
the engine.
INSPECTION
Inspect the plunger and plunger bore for cracks
and excessive wear. Polished surfaces are acceptable.
Verify that the plunger moves freely in the bore.
Check the spring for height and load limitations
(Fig. 153). Replace the spring if out of limits shown
in the figure.
