Drive Clutch Spring Inspection
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. If
weights or bolts are worn or broken, replace in sets of
three with new bolts and nuts.
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”.
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.
