SERVICE PROCEDURES
CLUTCH COMPONENT LUBRICATION
Proper clutch component lubrication is important
to satisfactory operation . Using the correct lubricant
and not over lubricating are equally important . Apply
recommended lubricant sparingly to avoid disc and
pressure plate contamination .
Clutch and transmission components requiring
lubrication are :
" Pilot bearing
" Release lever pivot ball stud'
" Release lever contact surfaces
" Release bearing bore
" Clutch disc hub splines
" Clutch pedal pivot shaft bore
" Clutch pedal bushings
" Input shaft splines
" Input shaft pilot hub
" Transmission front bearing retainer slide surface
NOTE : Never apply grease to any part of the clutch
cover, or disc .
RECOMMENDED LUBRICANTS
Use Mopar multi-purpose grease for the clutch
pedal bushings and pivot shaft . Use Mopar high tem-
perature grease (or equivalent) for all other lubrica-
tion requirements . Apply recommended amounts and
do not over lubricate .
CLUTCH LINKAGE FLUID
The integral clutch master cylinder reservoir, slave
cylinder and fluid lines are pre-filled with fluid prior
to assembly operations .
The hydraulic system should not require additional
fluid under normal circumstances . In fact, the reser-
voir fluid level will actually increase as normal
clutch wear occurs . For this reason, it is impor-
tant to avoid overfilling, or removing fluid from
the reservoir. This will cause clutch release
problems .
If inspection or diagnosis indicates additional fluid
may be needed, use Mopar brake fluid, or an equiv-
alent meeting standards SAE J1703 and DOT 3 . Do
not use any other type of fluid.
CLUTCH FLUID LEVEL
The clutch fluid reservoir, master cylinder, slave
cylinder and fluid lines are pre-filled with fluid at
the factory during assembly operations .
The hydraulic system should not require additional
fluid under normal circumstances . The reservoir
fluid level will actually increase as normal
clutch wear occurs . Avoid overfilling, or remov-
ing fluid from the reservoir .
If inspection or diagnosis indicates fluid level is
low, add Mopar brake fluid, or an equivalent meeting
standards SAE J1703 and DOT 3 . Do not use any
other type of fluid.
Clutch fluid level is checked at the master cylinder
reservoir (Fig . 3). An indicator ring is provided on the
outside of the reservoir. With the cap and diaphragm
removed, fluid level should not be above indicator
ring.
To avoid contaminating the hydraulic fluid during
inspection, wipe reservoir and cover clean before
removing the cap.

FLYWHEEL
Inspect the flywheel whenever the clutch disc,
cover and housing are removed for service . Check
condition of the flywheel face, hub, ring gear teeth,
and flywheel bolts .
Minor scratches, burrs, or glazing on the flywheel
face can be reduced with 180 grit emery cloth. How-
ever, the flywheel should be replaced if the disc con-
tact surface is severely scored, heat checked, cracked,
or obviously worn .
Flywheel machining is not recommended . The fly-
wheel surface is manufactured with a unique contour
that would be negated by machining . However,
cleanup of minor flywheel scoring can be performed
by hand with 180 grit emery, or with surface grind-
ing equipment . Replace the flywheel if scoring is
deeper than 0.0762 mm (0.003 in.).
Heavy stock removal by grinding is not recom-
mended . Excessive stock removal can result in fly-
wheel cracking or warpage after installation . It can
also weaken the flywheel and interfere with proper
clutch release .
Check flywheel runout if misalignment is sus-
pected. Runout should not exceed 0.08 mm (0 .003
in.). Measure runout at the outer edge of the fly-
wheel face with a dial indicator. Mount the dial indi-
