REPAIR FOR COMPONENT PARTS
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 average.
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 do not stick.
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.

NOTE:
Install two dish plates fitting each installation direction with
reverse clutch drum groove displaced slightly.
6. Install snap ring (1) using suitable tool (A).
7. Measure clearance between retaining plate and snap ring using
feeler gauge. If not within allowable limit, select proper retaining
plate.
8. Check operation of reverse clutch. Refer to TM-258, "

6. Remove cancel cover (1) and spring retainer assembly (2) from
input shaft assembly (high clutch drum) (3).
CAUTION:
Do not remove return springs from spring retainers.
7. Apply compressed air into the oil hole (A) at the location as
shown to remove high clutch piston from input shaft assembly
(high clutch drum).
CAUTION:
Do not blow air in too quickly, or high clutch piston and
ATF could jump out. Carefully blow air little by little while
protecting with lint-free cloth (B).
Block the oil hole on the opposite side with lint-free cloth
(B).
INSPECTION
High Clutch Snap Ring
Check for deformation, fatigue or damage. Replace if necessary.
High 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 average.
Inspect ALL drive plates.
Replace if the thickness is below the allowable limit.
High Clutch Spring Retainer Assembly
Check length (L) of springs retainer assembly. Replace if damaged,
deformed or worn.
CAUTION:
Do not remove return springs (A) from spring retainers (B).
