If greater than 15.88 mm (0.625 in) check possible disc
to flywheel bore interference.
11. Check Positive Separators.
Using a 6.35 mm (0.25 in) diameter flat nose drift, lightly
tap each of the four positive separator pins toward the
flywheel. After tapping, the pins should be flush against
the flywheel.
- - Remove rust and contamination from input shaft.
- - Replace the shaft if any wear is noticed. The clutch
won’t release if the shaft is notched.
- - Do not coat the shaft with grease or never seize.
Install discs dry or wipe on a light coat of oil.
If a clutch brake is used, be sure to install it on the input shaft
of the transmission at this time.
12. Refer to Installation of the Transmission, page 7-49, and
install the transmission.
Clutch Adjustment Procedure
Remove the inspection plate from the bottom of the clutch
housing and make the following inspections and adjustments
if required.
The release levers of new or factory exchange cover
assemblies are properly adjusted and locked at assembly
and will not require further adjustment. However, after the
transmission has been securely attached to the engine, the
release sleeve must be adjusted until the correct distance
between the surface of the release bearing housing and the
front brake disc is obtained.
1. Clutch brake squeeze should begin 25.4 mm (1.0 in)
above the pedal stroke. This is controlled by adjusting
the rod end bearings evenly at each rod end. Lengthen
the rod to squeeze closer to end of pedal stroke.
2. Visually check the travel of the release bearing after
working the pedal several times. Release travel should
be 12.7 to 14.3 mm (0.5 to 0.5625 in).
3. Make internal clutch adjustment for proper clearance as
follows.
a. Insert a 3/4 inch socket (12 points) or a 3/4 inch box
end wrench through the inspection hole and
depress the square headed bolt to adjust the clutch.
