REPAIR FOR COMPONENT PARTS

Reverse Clutch


COMPONENTS












DISASSEMBLY

1.Check operation of reverse clutch a.Install seal rings to drum support of oil pump assembly, and set reverse clutch assembly.





b.Apply compressed air into the oil hole at the location as shown.
c.Check to see that retaining plate moves to snap ring.
d.If retaining plate does not contact snap ring:
- D-ring might be damaged.
- Seal lip might be damaged.
- Fluid might be leaking past piston check ball.





2.Remove snap ring (1) using a suitable tool (A).
3.Remove retaining plate, drive plates, driven plates and dish plates.





4.Set Tool (A) on spring retainer assembly, and remove snap ring (1) from reverse clutch drum while compressing spring retainer assembly.
Tool number:KV-31103200 (J-39186)

CAUTION:
Set SST directly over return springs.
5.Remove spring retainer assembly from reverse clutch drum.

CAUTION:
Do not remove return springs from spring retainer.





6.Install seal rings to drum support of oil pump assembly (1), and set reverse clutch drum (2). Then apply compressed air into the oil hole at the location as shown in the figure to remove reverse clutch piston (3) from reverse clutch drum (2).

CAUTION:
Do not flow air in too quickly or reverse clutch piston (3)
and ATF could jump out. Carefully flow air in little by little while protecting with lint-free cloth.





7.Remove D-ring (1) and seal lip (2) from reverse clutch piston (3).

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.

Thickness of drive plate
Standard and allowable limit:
Clutches And Brakes.

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.
Thickness of dish plate (t):2.87 mm (0.1130 in)
Reverse Clutch Spring Retainer Assembly





Measure length (L) of spring retainer assembly. Replace if damaged, deformed or worn.
Length (L): 20.1 mm (0.791 in)

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.

ASSEMBLY






1.Install D-ring (1) and seal lip (2) on reverse clutch piston (3).

CAUTION:
Be careful with the direction of seal lip (2).





2.Install reverse clutch piston by turning it slowly.

CAUTION:
Apply ATF to inner surface of reverse clutch drum.





3.Install spring retainer assembly (1) to reverse clutch piston (2).





4.Set Tool (A) on spring retainer assembly, and install snap ring (1) while compressing spring retainer assembly.
Tool number:KV-31103200 (J-39186)

CAUTION:
Set SST directly over return springs.





5.Install dish plates, driven plates, drive plates and retaining plate.
(1): Snap ring (2): Retaining plate (3): Drive plate (4): Driven plate (5): Dish plate
Drive plate/Driven plate: 2/2

CAUTION:
Be careful with the order of plates.
NOTE:





Install two dish plates fitting each installation direction with reverse clutch drum groove displaced slightly.





6.Install snap ring (1) using a suitable tool (A).





7.Measure clearance between retaining plate and snap ring using feeler gauge. If not within allowable limit, select proper retaining plate. Refer to "Parts Information" for retaining plate selection.

Specified clearance
Standard and allowable limit:
Clutches And Brakes.

8.Check operation of reverse clutch.
