Overrun Clutch Piston

Make sure that check balls are not fixed.

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

Apply compressed air to oil hole on return spring side. Make
sure that air leaks past ball.
ASSEMBLY
1. Install seal lips (1) and D-rings (2) on forward clutch piston (3)
and overrun clutch piston (4).
CAUTION:
Be careful to direction of seal lips (1).
2. Install overrun clutch piston on forward clutch piston by turning it
slowly.
CAUTION:
Apply ATF to inner surface of forward clutch piston.
3. Install forward clutch piston with overrun clutch piston on for-
ward clutch drum by turning it slowly.

6. In order to remove low & reverse brake piston, apply com-
pressed air to oil hole of retainer while holding piston.
CAUTION:
Apply air gradually and allow low & reverse brake piston to
come out evenly.
7. Remove D-rings from low & reverse brake piston.
INSPECTION
Low & Reverse Brake Snap Ring and Spring Retainer
Check for deformation, fatigue or damage. Replace if necessary.
Low & Reverse Brake Drive Plate

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.
