DRIVE CLUTCH SPRING INSPECTION

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 relaxation the
spring is subject to during operation, it should always be
inspected for tolerance limits during any clutch operation
diagnosis or repair.
Check to see that spring coils are parallel to one another
using a straight-edge. Distortion of the spring indicates
stress fatigue, requiring replacement.
