Jeep XJ. Manual — part 60
(c) Starting 180 degrees from the last pilot bolt,
tighten 3 large hole bolts 3/4s of the way (any
sequence).
(d) Tighten 3 pilot hole bolts all the way (any
sequence).
(e) Starting 180 degrees from last pilot bolt,
tighten 3 large bolts all the way (any sequence).
(11) Apply light coat of Mopar
t high temperature
bearing grease to clutch disc hub and splines of
transmission input shaft. Do not over lubricate
shaft splines. This will result in grease contam-
ination of disc.
(12) Install transmission.
RELEASE BEARING
REMOVAL
(1) Remove transmission.
(2) Disconnect release bearing from release lever
and remove bearing (Fig. 12).
(3) Inspect bearing slide surface of transmission
front bearing retainer. Replace retainer if slide sur-
face is scored, worn, or cracked.
(4) Inspect release fork and fork pivot. Be sure
pivot is secure and in good condition. Be sure fork is
not distorted or worn. Replace release fork retainer
spring if bent or damaged.
INSTALLATION
(1) Lubricate crankshaft pilot bearing with Mopar
t
high temperature bearing grease. Apply grease to
end of long shank, small diameter flat blade screw-
driver. Then insert tool through clutch disc hub to
reach bearing.
(2) Lubricate input shaft splines, bearing retainer
slide surface, fork pivot and release fork pivot surface
with Mopar
t high temperature grease.
(3) Install new release bearing. Be sure bearing is
properly secured to release fork.
(4) Install transmission.
PILOT BEARING
REMOVAL
(1) Remove
transmission.
Refer
to
Group
21,
Transmission and Transfer Case, for proper proce-
dures.
(2) Remove clutch cover and disc.
(3) Use a suitable blind hole puller to remove pilot
bearing.
INSTALLATION
(1) Clean bearing bore with solvent and wipe dry
with shop towel.
(2) Lubricate new pilot bearing with Mopar
t high
temperature grease.
(3) Position and start new bearing in bearing bore
by hand. Note that pilot bearing has seal at one end.
Install bearing so seal is facing outward toward
transmission.
(4) Seat pilot bearing with clutch alignment tool
(Fig. 13). Keep bearing straight during installation.
Do not allow bearing to become cocked. Tap bearing
into place until flush with edge of bearing bore. Do
not recess bearing.
(5) Install transmission. Refer to Group 21, Trans-
mission and Transfer Case, for proper procedures.

REMOVAL AND INSTALLATION (Continued)
CLUTCH HOUSING
The clutch housing is removable and can be
replaced when the transmission is out of the vehicle.
The bolts attaching the housing to the transmis-
sion case are located inside the housing (Fig. 14).
Recommended tightening torque for the clutch hous-
ing-to-transmission bolts is 46 N·m (34 ft. lbs.).
NOTE: Be sure the transmission and housing mat-
ing surfaces are clean before installing an original,
or replacement clutch housing. Dirt/foreign material
trapped between the housing and transmission will
cause misalignment. If misalignment is severe
enough, the result will be clutch drag, incomplete
release and hard shifting.
CLUTCH HYDRAULIC LINKAGE
The clutch master cylinder, slave cylinder and con-
necting line are serviced as an assembly only. The
linkage components cannot be overhauled or serviced
separately. The cylinders and connecting line are
sealed units. Also note that removal/installation pro-
cedures for right and left hand drive models are basi-
cally the same. Only master cylinder location is
different.
REMOVAL
(1) Raise vehicle.
(2) Remove fasteners attaching slave cylinder to
clutch housing.
(3) Remove slave cylinder from clutch housing
(Fig. 15).
(4) Disengage clutch fluid line from body clips, if
applicable.
(5) Lower vehicle.
(6) Verify that cap on clutch master cylinder reser-
voir is tight. This is necessary to avoid spilling fluid
during removal.
(7) Remove clutch master cylinder attaching nuts
(Fig. 16) or (Fig. 17).
(8) Disengage captured bushing on clutch master
cylinder actuator from pivot pin on pedal arm (Fig.
18).
(9) Slide actuator off pivot pin.
(10) Disconnect
clutch
interlock
safety
switch
wires.
(11) Remove
clutch
hydraulic
linkage
through
engine compartment.

REMOVAL AND INSTALLATION (Continued)
INSTALLATION
(1) Be sure reservoir cover on clutch master cylin-
der is tight to avoid spills.
(2) Position clutch linkage components in vehicle.
Work connecting line and slave cylinder downward
past engine and adjacent to clutch housing (Fig. 16)
or (Fig. 17).
(3) Position clutch master cylinder on dash panel
(Fig. 16) or (Fig. 17).
(4) Attach clutch master cylinder actuator to pivot
pin on clutch pedal (Fig. 18).
(5) Install and tighten clutch master cylinder
attaching nuts to 38 N·m (28 ft. lbs.) torque.
(6) Raise vehicle.
(7) Insert slave cylinder push rod through clutch
housing opening and into release lever. Be sure cap
on end of rod is securely engaged in lever. Check this
before installing cylinder attaching nuts.
(8) Install and tighten slave cylinder attaching
nuts to 23 N·m (17 ft. lbs.) torque.
