SPRING FREE LENGTH
Measure the drive and driven spring free length with the
spring resting on a flat surface. Replace spring if out of
specification.
In addition to proper free length, the spring coils should
be parallel to one another when placed on a flat surface.
Distortion of the spring indicates stress fatigue.
Replacement is required.
IMPORTANT
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.
