CLUTCHING (PVT)
Drive Clutch Spring Inspection
A
CAUTION
Never shim a drive clutch spring to increase its
compression rate. This may result in complete
stacking of the coils and subsequent clutch
cover failure.
The drive clutch spring is one of the most critical components
of the PVT system.
It
is also one of the easiest to service. Due
to the severe relaxation the spring is subject to during operation,
it should always be inspected for tolerance limits during any
clutch operation diagnosis or repair.
With the spring resting on a flat surface, measure its free length
from the outer coil surfaces. Also check to see that spring coils
are parallel to one another. Distortion of the spring indicates
stress fatigue, requiring replacement.

Needle Bearing Inspection
1.
Rotate the clutch bearing in both clockwise and counter-
clockwise directions. The non-braking needle bearing
should rotate in both directions on the shaft with only a
slight amount of drag.
2.
Verify there is no binding or rough spots.
If
problems are
noted continue with disassembly.
Shift Weight Inspection
1.
Remove shift weight bolts and weights. Inspect the contact
surface of each weight. The surface should be smooth and
free of dents or gall marks. Inspect the weight pivot bore
and bolts for wear or galling. Ifweights or bolts are worn
or broken, replace in sets of three with new bolts and nuts.
A
WARNING
The clutch assembly is a precisely balanced
unit. Never replace parts with used parts from
another clutch assembly!
NOTE: A damaged shift weight is usually caused by
a damaged or stuck roller in the spider assembly.
See "Drive Clutch Roller Pin and Button Service".
