10. Install seal rings to bearing retainer (1), and set forward clutch
drum. Then apply compressed air into the oil hole at the location
as shown in the figure to remove forward clutch piston from for-
ward clutch drum.
CAUTION:
Do not blow air in too quickly, or forward clutch piston and
ATF could jump out. Carefully blow air little by little while
protecting with lint-free cloth.
11. Remove seal lips (1) and D-rings (2) from forward clutch piston
(3) and overrun clutch piston (4).
INSPECTION
Forward Clutch and Overrun Clutch Snap Rings
Check for deformation, fatigue or damage. Replace if necessary.
Forward Clutch and Overrun 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.
Forward Clutch and Overrun Clutch Dish Plates
• Check for deformation or damage.
• Measure thickness (t) of dish plate. Replace if damaged, deformed
or worn.
