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.
Forward Clutch and Overrun Clutch Dish Plates

Check for deformation or damage.

Measure the thickness of dish plate.

If deformed or fatigued, replace.
Forward Clutch Drum

Make sure that check balls are not fixed.

Apply compressed air to check ball oil hole from the outside of
forward clutch drum. Make sure air leaks past ball.
