NO6OSAH
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.

5. A,PPLlCATlONOF GREASE TO RELEASE FORKAi&
(1) Apply a coating of the specified grease to the point of
contact with the fulcrum and the point of contact withi(the release bearing.
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.
(2) Apply a coating of the specified grease to the end of therelease cylinder’s push rod and to the push rod hole in
the release fork.
Specified grease: MOPAR Multi-mileage Lubricant
Part No.2525035 or equivalent
4. APPLICATION OF GREASE TO CLUTCH RELEASE
BEARING
Pack the inner surface of the clutch release bearing and thegroove with the specified grease.

Specified grease: MOPAR Multi-mileage Lubricant _
Part No.2525035 or equivalentCaution
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
Part No.2525035 or equivalent
(2) Using the special tool (clutch disc center guide),
position the clutch disc to the flywheel.
(3) Install the clutch cover assembly. Tighten the bolts a
little at a time, working in a diagonal sequence, finally
tightening them to the specified torque.

SERVICE ADJUSTMENT PROCEDURESENGINE COOLANT LEAK CHECK
NO7FAAE1. Loosen cap.
2.Confirm that the engine coolant level is up to the filler neck.3. Install a adapter to the water outlet fitting and apply
160
kPa (23 psi) pressure. Hold pressure for tvvo minutes, whilechecking for leakage from the radiator, hose or connec-
tionsCaution
Be sure to completely clean away moisture from the
places checked.When the tester
is removed, be careful not to spill anyengine coolant from
it.
Be careful, when installing and removing the tester andwhen testing, not
to deform the water outlet fitting.
4. If there is leakage, repair or replace the appropriate part.
CAP PRESSURE TESTNO’IFBAG
1. Use a special tool to attach the cap to the tester.
2.Increase the pressure until the indicator of the gauge stops
moving.Limit:
65 kPa (9.2 psi)Standard value:
75-105 kPa (11-15 psi)
3.Replace the cap if the reading does not remain at or abovethe limit.
NOTEBe sure that the cap is clean before testing, since rust or
other foreign material on the cap seal will cause an
improper indication.

(1) Place straight edge as shown in the illustration.(2) Measure the deflection with a force of 100
N(22lb4applied to belt mid-point between water pump pulley and
alternator pulley. If the standard value is not obtained, make
adjustment.Standard
value:
8.0-11.0 mm (.315-433 in.)
<2.0L DOHC Engine> 9.0-I 1.5 mm (.354-.453 in.)(3) Use a tension gauge to check the belt tension. If the
standard value is not obtained, make adjustment.
When tension gauge is used, the tension may be measuredbetween any two pulleys.Standard

Caution
Excessive belt tension will cause damage to alternator and
water pump pulley bearings, while on the other hand,
loose belt tension will produces slip.
Therefore, be sure to adjust the belt tension to proper
value.

(1) Loosen the nut on the alternator support bolt.
(2) Loosen the alternator brace bolt.
(3) Make sure that the belt is properly installed in pulley
groove.
