Easy Pedal Advantage
Manual Adjust Clutches
Install Transmission
Check Transmission For Wear
Replace any worn components.
IMPORTANT
Do not add lube (never seize
or grease) to the input shaft
splines. The discs must be free
to move.
Input Shaft Splines
Any wear on the splines will
prevent the driven discs from
sliding freely, causing poor
clutch release (clutch drag).
Slide disc
s full length of shaft to
check for twisted shaft splines.
Clutch Brake
Replace.
Cross Shaft and Bushings
Excessive wear at these points can cause
side loading on the sleeve bushing,
bushing failures and yoke bridge contact
with the clutch when the pedal is down.
Measure Input Shaft
Length should be 8.657" (219.89 mm) nominal, and
not greater than 8.71" (221.23 mm). Ref. 1990 SAE
handbook 4:36.106. Replace transmission bearing
retainer cap if length is greater than 8.71" (219.89 mm).
Transmission Bearing
Retainer Cap
A worn/rough bearing
retainer cap may cause
the clutch brake to wear
prematurely.
Release Yoke
Worn fingers can cause
bushing wear and yoke
interference when the
pedal is down.
Input Shaft
Wear (roughness) can
reduce sleeve bushing life
and cause it to come out.
CAUTION
Do not excessively force the transmission
into the clutch assembly or engine
housing. This will cause damage to the
splines of the rear disc hub that is not
warrantable. If the discs do not slide freely
on the input shaft, investigate the cause of
the problem and make any necessary
change
s. If the discs do not slide freely, the
clutch will not release and the transmission
will grind going into gear.
Do not let the transmission drop or hang
unsupported in the driven discs. This can
bend the discs and the clutch will not
release causing damage that is n
ot
warrantable.
Input Shaft Spigot
Wear will not provide proper
interface with the inner race of
the pilot bearing. This can
result in damage to the clutch
or the pilot bearing.
