Drive Clutch Spring Inspection
The d rive clu tch sp ring is on e of the most critical
components of t he PVT system. It is also one of t he
easiest to service. Due to the severe relaxation the spring
is su bject to du ring op eration, it sh ould alw ays be
inspected for tolerance limits during any clutch operation
diagnosis or repair.
With the spring resting on a flat surface, measure its free
le
ngth from the outer coil surfaces. Also check to see that
spring coils a re parallel to one another. Distortion of the
spring indicates stress fatigue, requiring replacement.
Shift Weight Inspection
1. Remove shift weight bolts and weights . Inspect the
contact surface of the 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 da
maged or st uck rolle r in the spider assembly.
See “Roller, Pin and Thrust Washer Inspection”.
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.
