(8) Starting with the bolts marked “P” on the cover
first. Tighten the bolts in a star pattern to 50 N·m
torque (37 ft. lbs.).

Refer to 21, Transmission and Transfer Case for pro-
cedure.
FLYWHEEL
REMOVAL
(1) Remove transmission and clutch housing.
(2) Remove clutch cover and disc.
(3) Remove pilot bearing retainer bolts and remove
retainer/pilot bearing from the flywheel (Fig. 5).
(4) Remove flywheel bolts and grasp flywheel
firmly and work it off the crankshaft flange.
(5) Remove the O-ring from the mounting shoulder
of the flywheel.
(6) Clean the flywheel in solvent.
INSPECTION
Inspect flywheel mounting surfaces, clutch contact
surface, and ring gear. Inspect condition of flywheel
hub and attaching bolts. Replace flywheel if hub
exhibits cracks in the area of attaching bolt holes.
Replace ring gear if the teeth are damaged. Resur-
face flywheel if clutch contact surface is scored or
rough.
Check flywheel runout if suspected. Mount a indi-
cator on a stud installed in the engine block (Fig. 6)
to measure runout. Runout should not exceed 0.08
mm.
NOTE: Runout can be corrected by resurfacing.
Surface grinding equipment is recommended for
this purpose. Stock removal should not exceed 0.25
mm.

INSTALLATION
(1) Clean crankshaft flange of dirt and grease.
(2) Install new O-ring in the flywheel mounting
flange. Use grease to hold the ring in place.
(3) Install flywheel on the crankshaft and align
the bolt holes.
(4) Lubricate and install the new flywheel bolts.
(5) Starting with one bolt and tighten to 49 N
•m
(36 ft. lbs.). Following with the opposite one (cross
tightening) in a clockwise direction (Fig. 7).
(6) Loosen one bolt at a time, then tighten to 19.6
N
•m (14 ft. lbs.) plus 75° using the cross tightening
method until completion.
(7) Install clutch cover and disc.
(8) Install transmission and transfer case.
RING GEAR
REMOVAL
WARNING: WEAR SAFETY GOGGLES FOR THIS
PROCEDURE.
(1) Remove flywheel from the vehicle.
(2) Mark position of the gear on the flywheel for
installation reference.
(3) Cut the gear most of the way through at one
point with an abrasive cut off wheel.
(4) With a hammer and cold chisel break the ring
gear at the cut point.
INSTALLATION
CAUTION: Never use an oxy/acetylene torch to
remove the old gear or to heat and expand a new
gear. The high temperature of the torch flame can
cause localized heating that will damage the fly-
wheel. In addition, using the torch to heat a replace-
ment
gear
will
cause
uneven
heating
and
expansion. The torch flame can also anneal the
gear teeth resulting in rapid wear and damage after
installation.
WARNING: WEAR SAFTEY GOGGLES AND HEAT
RESISTANT GLOVES TO HANDLE THE HOT RING
GEAR.
(1) Heat new ring to 350°-375°.
NOTE: Every surface of the gear must be heated at
the same time to produce uniform expansion. An
oven or similar enclosed heating device must be
used. Temperature required for uniform expansion
is approximately 350°-375°
(2) Position heated ring gear on the flywheel. Align
the ring gear on the flywheel evenly
(3) Tap the ring gear onto the flywheel with a
hammer and brass drift.
(4) Allow ring gear to cool down before installation
on the engine. Place flywheel on work bench and let
it cool in normal shop air.
(5) Install the flywheel in the vehicle
PILOT BEARING
REMOVAL
(1) Remove transmission, refer to 21 Transmission
and Transfer Case for procedures.
(2) Remove clutch cover and disc.
(3) Remove pilot bearing retainer bolts (Fig. 8).

letters on the bearing facing out (toward rear of
vehicle).
(1) Install new pilot bearing with correct size
driver and handle (Fig. 10).
NOTE: Seat bearing flush with lower edge of cham-
fer in retainer bore (Fig. 11).
(2) Install bearing retainer and tighten bolts to 28
N·m (20 ft. lbs.)
(3) Lubricate the pilot bearing with Mopar
t high
temperature or equivalent.
(4) Install clutch disc and cover.
(5) Install transmission, refer to 21 Transmission
and Transfer Case for procedures.
