INSPECTION
Snap Rings, Spring Retainer and Return Springs

Check for deformation, fatigue or damage.

Replace if necessary.

When replacing spring retainer and return springs, replace them as a set.
Forward Clutch and Overrun Clutch Drive Plates

Check facing for burns, cracks or damage.

Measure the thickness of facing.

If not within wear limit, replace.
