DIAGNOSIS A N D TESTING (Continued)
(6) Check to see i f the clutch disc hub splines are
damaged. Replace w i t h new disc i f required.
(7) Check for uneven wear on clutch fingers.
Replace clutch cover (pressure plate) i f required.
(8) Check pilot bearing located i n the crank shaft
of the engine. Also check the i n p u t shaft nose for
nicks burrs or damage. Replace parts as required.
(9) To reinstall, See Clutch Cover and Disc

CLUTCH COMPONENT LUBRICATION
Proper clutch component lubrication is i m p o r t a n t
to satisfactory operation. Using the correct lubricant,
but avoid using an excessive amount.
D u r i n g service, apply recommended lubricant spar-
ingly. Excessive lubricant could result i n clutch disc
and clutch cover (pressure plate) contamination.
Clutch components requiring lubrication are the
splines i n the clutch disc hub and clutch pedal pivot
bore and bushings. Transmission components requir-
i n g lubrication are the i n p u t shaft splines and the
release bearing slide surface of the front bearing
retainer. D o n o t apply- g r e a s e t o a n y p a r t o f t h e
c l u t c h cover,, d i s c o r r e l e a s e b e a r i n g .
Use Mopar multi-purpose grease or a silicone
grease for the clutch pedal bushings and pivot shaft.
Use Mopar H i g h Temperature Wheel Bearing Grease
or equivalent for a l l other clutch lubrication require-
ments. Apply recommended amounts only.
HYDRAULIC CLUTCH LINKAGE BLEED
PROCEDURE
To determine i f the master cylinder assembly
requires bleeding or i f the complete system requires
bleeding:
(1) Uncouple the clutch master cylinder line from
the clutch slave cylinder. Use the quick disconnect
tool (Special Tool 6638) to open the coupling.
(2) Apply force to the clutch pedal to stroke i t . Do
not apply too much force as this w i l l cause the
uncoupled male coupling to blow out.
(3) I f the pedal feels h a r d i n a relatively short dis-
tance, air is present i n the clutch slave cylinder.
(4) I f the pedal feels spongy air is present i n the
master cylinder assembly.
COMPLETE SYSTEM BLEED
(1) Remove the reservoir cap and diaphragm tak-
i n g care not to damage the diaphragm (Fig. 2). I f the
fluid level is not up to the step i n the reservoir, add
D.O.T. 4 brake
fluid.

(2) While slowly depressing the clutch pedal, open
the bleed screw on the clutch slave cylinder.
(3) While holding down the clutch pedal retighten
the bleed screw. Tighten the bleed screw to 15-20
N - m (11-14 ft. lbs.).
(4) Repeat Step 2 and Step 3 two times. Recheck
fluid level i n reservoir per Step 1.
(5) Pump the clutch pedal as rapidly as possible a
m i n i m u m of 10 times.
(6) I f clutch pedal s t i l l feels spongy, repeat Step 2
through Step 5.

(3) Open the male quick connect coupling by
depressing the poppet i n the coupling while stroking
the clutch pedal to the floor.
(4) Close the quick connect coupling by releasing
the poppet while holding the clutch pedal to the floor.
(5) Release the pedal.
(6) Repeat Step 3 through Step 5 two more times
and check fluid level as i n Step 2.
