CLUTCHING

DRIVE CLUTCH 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.
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 stress 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.
