Clutch disc
1. Clean the clutch disc splines and main drive gear splines;
then apply organic molybdenum sulfide grease.
2. Hold the clutch disc in position with the
SST.
Clutch cover
1. Install the SST or equivalent.
2. Align the dowel holes with the flywheel dowels.
3. Tighten the bolts evenly and gradually in the pattern shown.
Tightening torque:
18-26 Nom (1.8-2.7 m-kg, 13-20 ft-lb)
RELEASE BEARING
INSPECTION
Note
l The clutch release bearing Is a sealed bearlng and
must not be washed in solvent.
1. Turn the bearing while applying force in the axial direction.
If the bearing sticks or has excessive resistance, replace it.
CLUTCH COVER
INSPECTION
Note
l Minor scoring or burning should be removed with
emery paper.
1. Inspect the contact surface of the clutch disc for scoring,
cracks, and burning. Repair or replace as necessary.
2. Inspect the contact surface of the clutch release bearing
for wear and cracks.
If there is wear or cracks, replace the clutch cover.
CLUTCH DISC
INSPECTION
Note
l Use sandpaper if the trouble is minor.
1. Inspect the lining surface for burning and oil contamination.
Replace the clutch disc if it is badly burned or oil soaked.
2. Inspect for loose facing rivets and rubbers.
Replace the clutch disc if either is loose.

3. Measure the thickness of the lining at a rivet head on both
sides with vernier calipers.
Replace the clutch disc if its thickness is less than minimum.
Thickness: 0.3mm (0.012 in) min.
4. Measure the clutch disc runout with a dial indicator.
Replace the clutch disc if runout is excessive.
Runout: 0.7mm (0.027 in) max.
PILOT BEARING
INSPECTION
1. Turn the bearing while applying force in the axial direction.
If the bearing sticks or has excessive resistance, replace it.

FLYWHEEL
INSPECTION
Note
l Minor scoring or burning should be removed with
emery paper.
1. Inspect the contact surface of the clutch disc for scoring,
cracks, and burning; repair or replace as necessary.
2. Inspect the ring gear teeth for wear and damage. If neces-
sary, replace the ring gear.
3. Measure the flywheel runout with a dial indicator. Replace
