Solo Advantage
Self-Adjusting 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.
Note: Adjust the linkage until pushing
the pedal down moves the bearing
against the clutch brake. Let up on the
pedal and measure the distance
between the bearing and clutch brake
(distance shou
ld be 0.490"-0.560").
Input Shaft Splines
Any wear on the splines will
prevent the driven discs from
sliding freely, causing poor
clutch release (clutch drag).
Slide discs full length of shaft to
check for twisted shaft splines.
Clutch Brake
Replace.
Cross Shaft and Bushings
Excess
ive 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
r
educe sleeve bushing life
and cause it to come out.
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.
CAUTION
Do not use the cross-shaft release lever (or
a pipe over it) to pull the transmission into
its final position. Pulling the bearing too far
during installation can cause an overstroke
causing the release bearing to move closer
to the transmission (less than
0.490") with
this condition. Follow the Out of Vehicle
Resetting Procedure on page 1.
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 not warrantable.
Do not excessively force the transmissio
n
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
in the input shaft, investigate the cause of
the problem and make any necessary
changes. If the discs do not slide freely, the
cl
utch will not release and the transmission
will grind going into gear.
