DRIVE CLUTCH SERVICE
Spring Specifications
The drive clutch spring has two primary functions:
1. To control clutch engagement RPM. The springs
which have a higher rate when the clutch is in neutral
will increase clutch engagement RPM.
2. To control the rate at which the drive belt moves
upward in the drive clutch sheaves. This is referred
to as drive clutch upshift.
There are other components which control upshift, but the
spring is one of the primary components in insuring
optimum performance. It is very important that the spring
is of the correct design and is in good condition.
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 as shown. Refer to the spring specification chart for specific free
length measurements and tolerances. Also check to see that spring coils are
parallel to one another. Distortion of the spring indicates stress fatigue,
requiring replacement.
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.
