1. REMOVAL OF CLUTCH COVER ASSEMBLY/P.
CLUTCH DISCDiagonally loosen bolts which attach clutch cover to
flywheel. Back off bolts in succession, one or two turns at atime, to avoid bending cover flange.
Caution
DO NOT clean clutch disc or release bearing with
cleaning solvent.
INSPECTIONNlNGCAB
CLUTCH COVER ASSEMBLYl Check the diaphragm spring end for wear and uneven
height.
Replace
If wear is evident or height difference exceeds the
limit.Limit
: 0.5 mm (.02 in.)l
Check the pressure plate surface for wear, cracks and color
change.lCheck the strap plate rivets for looseness and replace the
clutch cover assembly if loose.
CLUTCH DISCl
Check the facing for loose rivets, uneven contact, deteriora-tion due to seizure,
adhesron of oil or grease and replace
the clutch disc if defective.
l
Measure the rivet sink and replace the clutch disc if it is outof specification.Limit
: 0.3 mm (.012 in.)l
Check for torsion spring play and damage and if defective,replace the clutch disc.
l Combine the clutch disc with the input shaft and check
sliding condition and check for play in the rotating direction.If it does not slide smoothly, check after cleaning and
reassembling. If the play IS excessive, replace the clutch
drsc and/or the input shaft.
CLUTCH RELEASE BEARING
Caution
The release bearing is packed with grease, so don’t use
cleaning oil, etc. to clean it.l Check for
beanng heat damage, other damage, abnormal
noise and/or improper rotation. Also check whether or not
there IS wear at the point of contact with the diaphragm
spring.lIf there is abnormal wear at the pornt of contact with the
release fork, replace the bearing.
RELEASE FORKlIf there is abnormal wear at the
pornt of contact with the
bearing, replace the release fork.

Specified grease: MOPAR Multi-mileage Lubricant
Part Nq.2525035 or equivalentCautionWhen installing the
clutch, apply grease to each
part, but be careful not to apply excessive grease;
excessive grease will cause clutch slippage and
shudder.

For the release bearing of a resin sleeve, grease mustnot
be applied to the sleeve part.
2. APPLICATION OF GREASE TO CLUTCH DISC/ 1.
CLUTCH COVER ASSEMBLY
(1) Apply a coating of the specified grease to the clutch
disc spline, and then use a brush to rub it in.
Specified grease: MOPAR Multi-mileage Lubricant
