truding through cover plate stamping and release
sufe plate assembly.
fork ball fulcrum with high melting point wheel bear-
ing lubricant and install release fork.
INSPECTION
Inspect clutch driven plate for broken or distorted
torsion springs, worn or loose facings, oil on facings
or damaged spline which could cause binding. If any
of the above defects are present, replace driven plate
with new assembly.
Inspect clutch cover-pressure plate assembly to see
that it is free of oil and grease. Check pressure plate
for scores or cracked surface.
NOTE: Servicing of clutch driven plate or
clutch cover-pressure plate assembly must be
made by replacement of assemblies only.
Examine transmission bearing retainer carefully to be
certain there are no burrs on outer surface which
pilots the clutch release bearing.
Try clutch release bearing on transmission bearing
retainer to make sure that no binding exists.
Check clutch release bearing by placing thrust load
on bearing by hand and turning bearing race. Replace
if bearing feels rough or seems noisy when turning.
Clean flywheel face with cleaning solvent, sandpaper
or steel wool. Inspect pilot bearing in crankshaft for
roughness.
REPLACE
1. Position clutch driven plate so that long end of hub
is in flywheel and install clutch driven plate and
clutch cover assembly on flywheel but do not tighten
bolts (install lock washer under each cover-to-fly-
wheel bolt).
NOTE: Align marks placed on flywheel and on
cover during disassembly.
2. Use a spare transmission main drive gear, inserted in
spline of clutch driven disc, to move disc into correct
alignment so pilot on end of drive gear will enter
clutch pilot bearing. Tighten clutch cover and pres-
sure plate-to-flywheel bolts one at a time until snug,
then tighten to 25 lb. ft. torque. Remove spare main
drive gear used to align clutch disc.
3. Lubricate surface of release fork fingers which con-
tact release bearing, sides of pressure plate lugs pro-
4. Apply a light coat of grease to inner diameter of
clutch release bearing and fill recess in inner diameter
of bearing.
5. Install clutch release bearing to fork in flywheel hous-
ing.
NOTE: When installing a new bearing, be sure
the same length bearing is installed as was
removed.
6. Apply a light coat of high melting point wheel bear-
ing lubricant to full length of outer diameter of trans-
mission release bearing support (retainer).
CAUTION: Do not over lubricate.
7. Install flywheel housing and tighten bolts to 40 lb. ft.
torque.
8. Install transmission. See applicable TRANSMIS-
SION SECTION.
CAUTION: Use two transmission guide pins in
upper holes in clutch housing.
9. Connect clutch linkage to release fork.
10. Adjust pedal lash. See Clutch Pedal Adjustment un-
der ON CAR ADJUSTMENTS.
NOTE: If interfrence is encountered with the
clutch fully engaging, the transmission shifr
linkage should be adjusted as outlined in Sec-
tions 7A thru 70, because the shifr linkage in-
terlock mechanism is controlled by &tch
action.
FLYWHEEL OR CLUTCH PILOT BEARING
REMOVE A N D REPLACE
1. Remove transmission.
2. Remove clutch assembly.
3. If clutch pilot bearing is to be replaced, use cold
chisel to remove staking in end of crankshaft which
keeps bearing in place when transmission is removed
(Fig. 7-9). Remove clutch pilot bearing from hole in
crankshaft.
