Jeep XJ. Manual - part 411

(10) Install all bolts that attach support to pump

housing. Then tighten bolts finger tight.

(11) Tighten support-to-pump bolts to required

torque as follows:

(a) Reverse pump assembly and install it in

transmission case. Position pump so bolts are fac-
ing out and are accessible.

(b) Secure pump assembly in case with 2 or 3

bolts, or with pilot studs.

ft. lbs.).

(d) Remove pump assembly from transmission

case.
(12) Install new oil seal in pump with Special Tool

C-4193 and Tool Handle C-4171 (Fig. 183). Be sure
seal lip faces inward.

(13) Install new seal ring around pump housing.

Be sure seal is properly seated in groove.

(14) Lubricate lip of pump oil seal and O-ring seal

with transmission fluid.

FRONT CLUTCH

DISASSEMBLY

(1) Remove waved snap ring and remove pressure

plate, clutch plates and clutch discs (Fig. 184).

(2) Compress clutch piston spring with Compressor

Tool C-3575-A (Fig. 185). Be sure legs of tool are
seated squarely on spring retainer before compress-
ing spring.

(3) Remove retainer snap ring and remove com-

pressor tool.

(4) Remove spring retainer and clutch spring. Note

position of retainer on spring for assembly reference.

(5) Remove clutch piston from clutch retainer.

Remove piston by rotating it up and out of retainer.

(6) Remove seals from clutch piston and clutch

retainer hub. Discard both seals as they are not reus-
able.

ASSEMBLY

(1) Soak clutch discs in transmission fluid while

assembling other clutch parts.

(2) Install new seals on piston and in hub of

retainer. Be sure lip of each seal faces interior of
clutch retainer.

(3) Lubricate lips of piston and retainer seals with

liberal quantity of Mopar

t Door Ease, or Ru-Glyde.

Then lubricate retainer hub, bore and piston with
light coat of transmission fluid.

(4) Install clutch piston in retainer (Fig. 186). Use

twisting motion to seat piston in bottom of retainer. A
thin strip of plastic (about 0.020” thick), can be used
to guide seals into place if necessary.

CAUTION: Never push the clutch piston straight in.
This will fold the seals over causing leakage and
clutch slip. In addition, never use any type of metal
tool to help ease the piston seals into place. Metal
tools will cut, shave, or score the seals.

(5) Position spring in clutch piston (Fig. 187).
(6) Position spring retainer on top of piston spring

(Fig.

188).

Make

sure

retainer

properly

installed. Small raised tabs should be facing
upward. Semicircular lugs on underside of
retainer are for positioning retainer in spring.

(7) Compress piston spring and retainer with Com-

pressor Tool C-3575-A (Fig. 185). Then install new
snap ring to secure spring retainer and spring.

(8) Install clutch plates and discs (Fig. 184).

Install steel plate then disc until all plates and discs
are installed. The front clutch uses 4 clutch discs.

(9) Install pressure plate and waved snap ring

(Fig. 184).

(10) Using a suitable gauge bar and dial indicator,

measure clutch plate clearance (Fig. 189).

(a) Position gauge bar across the clutch drum

with the dial indicator pointer on the pressure
plate (Fig. 189).

(b) Using two small screw drivers, lift the pres-

sure plate and compress the waved snap-ring. This

will assure that the snap-ring is at the top of the
groove.

indicator.

(d) Lift the pressure plate until it contacts the

waved snap-ring and record the dial indicator read-
ing.
Clearance should be 1.70 to 3.40 mm (0.067 to

0.134 in.). If clearance is incorrect, clutch discs,
plates pressure plates and snap ring may have to be
changed.

REAR CLUTCH

DISASSEMBLY

(1) Remove thrust washer from forward side of

clutch retainer.

(2) Remove input shaft front/rear seal rings.
(3) Remove selective clutch pack snap ring (Fig.

190).

plates, bottom pressure plate and wave snap ring
and wave spring (Fig. 190).

(5) Remove clutch piston with rotating motion.
(6) Remove and discard piston seals.
(7) Remove input shaft snap-ring (Fig. 191). It

may be necessary to press the input shaft in slightly
to relieve tension on the snap-ring

(8) Press input shaft out of retainer with shop

press and suitable size press tool. Use a suitably

sized press tool to support the retainer as close to the
input shaft as possible.

ASSEMBLY

(1) Soak clutch discs in transmission fluid while

assembling other clutch parts.

(2) Install new seal rings on clutch retainer hub

and input shaft if necessary (Fig. 192).

(a) Be sure clutch hub seal ring is fully seated in

groove and is not twisted.
(3) Lubricate splined end of input shaft and clutch

retainer with transmission fluid. Then press input
shaft into retainer. Use a suitably sized press tool to
support retainer as close to input shaft as possible.

(4) Install input shaft snap-ring (Fig. 191).
(5) Invert retainer and press input shaft in oppo-

site direction until snap-ring is seated.

(6) Install new seals on clutch piston. Be sure lip

of each seal faces interior of clutch retainer.

(7) Lubricate lip of piston seals with generous

quantity of Mopar

t Door Ease. Then lubricate

retainer hub and bore with light coat of transmission
fluid.

(8) Install clutch piston in retainer. Use twisting

motion to seat piston in bottom of retainer. A thin
strip of plastic (about 0.020” thick), can be used to
guide seals into place if necessary.
