of the spring bow outward, pushing the pre
ssure plate into closer contact with
the clutch disc. As the disc and plate mo ve closer together, friction between the
two increases and slippage is reduced until, when full spring pressure is applied
(by fully releasing the pedal) the speed of the disc and plate are the same. This
stops all slipping, creating a direct connection between the plate and disc which
results in the transfer of power from t he engine to the transmission. The clutch
disc is now rotating with the pressure plate at engine speed and, because it is
splined to the transmission shaft, the shaft now turns at the same engine speed.
The clutch is operating properly if: 1. It will stall the engine when released with the vehicle held stationary.
2. The shift lever can be moved freel y between 1st and reverse gears when
the vehicle is stationary and the clutch disengaged.
APPLICATION
All 1982-83 vehicles use a mechanical (non-hydraulic) clutch; 1984-92 models
use a hydraulic clutch. With the hydraulic clutch, no adjustment of the clutch
pedal or the linkage is required. On t he mechanical type, the only required
adjustment is to maintain the proper clutch pedal freeplay. The freeplay\
adjustment is very important, for it determines the engaging and disengaging
characteristics of the clutch assembly.
The clutch assembly consists of: a flywheel, a pressure plate, a throwout
bearing and fork, a clutch pedal, and an actuating lever (non-hydraulic) or a
master cylinder/slave cylinder (hydraulic).
The hydraulic system utilizes a remote re servoir which is mounted to the power
brake booster, a master cy linder mounted to the cowl p anel and a slave cylinder
that is mounted to the bell housing. Th e system is operated directly by the
clutch pedal. When adding fl uid to the reservoir, always use a type which meets
DOT 3 specifications.
CAUTION - The clutch driven disc contains asbestos, which has been
determined to be a cancer causing agen t. Never clean clutch surfaces with
compressed air! Avoid inhaling any dus t from any clutch surface! When
cleaning clutch surfaces, use a commercia lly available brake cleaning fluid.
FREE-PLAY ADJUSTMENT
MECHANICAL LINKAGE 1. Disconnect the return sp ring at the clutch fork.
2. Hold the pedal against the rubber bumper on the dash brace.
3. Push the clutch fork so that th e throwout bearing lightly contacts the
pressure plate fingers.

7. To install, reverse the removal
procedures. Torque the master cylinder-
to-cowl brace nuts to 10-15 ft. lbs. (14-20 Nm). Fill master cylinder with
new hydraulic fluid conforming to DO T 3 specifications. Bleed and check
the hydraulic clutch system for leaks.
OVERHAUL 1. Remove the filler cap and drain fl uid from the master cylinder.
2. Remove the reservoir and seal from the master cylinder. Pull back the
dust cover and remove the snapring.
3. Remove the push rod assembly. Usi ng a block of wood, tap the master
cylinder on it to eject the plunger a ssembly from the cylinder bore.
4. Remove the seal (carefully) from the front of the plunger assembly,
ensuring no damage occurs to the plunger surfaces.
5. From the rear of t he plunger assembly, remove the spring, the support,
the seal and the shim.
6. Using clean brake fluid, clean all of the parts.
7. Inspect the cylinder bore and t he plunger for ridges, pitting and/or
scratches, the dust cover for wear and cracking; replace the parts if any
of the conditions exist.
To assemble: 8. Use new seals, lubric ate all of the parts in clean brake fluid, fit the
plunger seal to the plunger and reve rse the disassembly procedures.
9. Insert the plunger assembly, va lve end leading into the cylinder bore
(easing the entrance of the plunger seal).
10. Position the push rod assembly into the cylinder bore, then install a new
snapring to retain the push rod. Install dust cover onto the master
cylinder. Lubricate the inside of t he dust cover with Girling® Rubber
Grease or equivalent.
Be careful not to use any lubricant that will deteriorate rubber dust covers or
seals.
SLAVE CYLINDER
On vehicles equipped with a hydraulic clutch release mechanism, the slave
cylinder is located on the left side of the bellhousing and controls the clutch
release fork operation.
REMOVAL & INSTALLATION
1. Disconnect the negative battery cable.
2. Raise and safely support the front of the vehicle on jackstands.
3. Disconnect the hydraulic line from clutch master cylinder. Remove the
line-to-chassis screw and the c lip from the chassis.

4. Remove the slave cyli
nder-to-bellhousing nuts.
5. Remove the push rod and the slav e cylinder from the vehicle, then
overhaul it (if necessary).
6. To install, reverse the removal pr ocedures. Lubricate leading end of the
slave cylinder with Girli ng® Rubber Lube or equiva lent. Torque the slave
cylinder-to-bellhousing nuts to 10-15 ft. lbs. (14-20 Nm). Fill the master
cylinder with new brake fluid conformi ng to DOT 3 specifications. Bleed
the hydraulic system.
OVERHAUL 1. Remove the shield, the pushrod and the dust cover from the slave cylinder, then inspect the cover for damage or deterioration.
2. Remove the snapring form t he end of the cylinder bore.
3. Using a block of wood, tap the slave cylinder on it to eject the plunger,
then remove the seal and the spring.
4. Using clean brake fluid, clean all of the parts.
5. Inspect the cylinder bore and the plunger for ridges, pitting and/or
scratches, the dust cover for wear and cracking; replace the parts if any
of the conditions exist.
To assemble: 6. Use new seals and lubricat e all of the parts in clean brake fluid. Install
the spring, the plunger seal and the plunger into the cylinder bore, then
install anew snapring.
7. Lubricate the inside of the dust co ver with Girling® Rubber Grease or
equivalent, then install it into the slave cylinder.
Be careful not to use any lubricant that will deteriorate rubber dust covers or
seals.
BLEEDING THE HYDRAULIC CLUTCH
Bleeding air from the hydrau lic clutch system is necessary whenever any part of
the system has been disconnect ed or the fluid level (in the reservoir) has been
allowed to fall so low that air has been drawn into the master cylinder.
1. Fill master cylinder reservoir wit h new brake fluid conforming to DOT 3
specifications.
2. Raise and safely support the front of the vehicle on jackstands.
3. Remove the slave cylinder attaching bolts.
4. Hold slave cylinder at approximatel y 45 degrees with the bleeder at
highest point. Fully depress clutch pedal and open the bleeder screw.
5. Close the bleeder screw and release clutch pedal.
6. Repeat the procedure until all of t he air is evacuated from the system.
Check and refill master cylinder reserv oir as required to prevent air from
being drawn through the master cylinder.

seal preload. Turn the torque wrenc
h smoothly for several rotations and
record the amount of preload as the a ssembly is turning, not the initial
force required to start the assembly moving.
Preload is measured as the amount of torque required to turn the assembly.
5. Using a suitable tool to hold the pi nion yoke in place, remove the pinion
yoke nut and washer.
6. Place a suitable contai ner under the differential to catch any fluid that
may drain from the rear axle. Using a suitable tool, remove the pinion
flange.
7. Use a suitable tool to remove the pinion seal.
To install: 8. Inspect the seal surface of the pinion flange for tool marks, nicks or
damage and replace, as necessary. Examine the carrier bore and
remove any burrs that might cause leaks around the outside of the seal.
9. Install the seal 0.010 in. (0.2 5mm) below the flange surface using a
suitable seal installer.
10. Apply suitable seal lubricant to t he outer diameter of the pinion flange
and the sealing lip of the new seal.
11. Install the pinion flan ge on the drive pinion by taping with a soft hammer
until a few pinion threads projec t through the pinion flange.
12. Install the washer and pinion fla nge nut. While holding the pinion flange,
tighten the nut a little at a time and turn the drive pinion several
revolutions after each tightening, to set the bearing rollers. Check the
preload each time with a suitable inch pound to rque wrench until the
preload is 5 inch lbs. (0.6 Nm) more then the reading obtained during
disassembly.
13. Install the driveshaft.
14. Install the rear wheels and tires. Check and add the correct lubricant, as
necessary.
AXLE HOUSING
REMOVAL & INSTALLATION 1. Raise the vehicle and support it sa fely. Be sure that the rear axle
assembly is supported safely.
