INSPECTION
Reverse Clutch Snap Ring
Check for deformation, fatigue or damage. Replace if necessary.
Reverse Clutch Drive Plates

Check facing for burns, cracks or damage. Replace if necessary.

Measure thickness of facing.
CAUTION:

Measure the thickness at 3 locations and find the aver-
age.

Inspect all drive plates.

Replace if the thickness is below the allowable limit.
Reverse Clutch Dish Plates

Check for deformation or damage.

Measure thickness (t) of dish plate. Replace if damaged,
deformed or worn.
Reverse Clutch Spring Retainer Assembly
Measure length (L) of spring retainer assembly. Replace if damaged,
deformed or worn.
CAUTION:
Do not remove return springs (A) from spring retainer (B)
Reverse Clutch Piston

Make sure that check balls are not fixed.

Apply compressed air to check ball oil hole opposite from return
spring. Make sure there is no air leakage.

Apply compressed air to oil hole on return spring side to make
sure that air leaks past ball.
Reverse Clutch Drum
Check for deformation or damage. Replace if necessary.Thickness of drive plate
