High Clutch

DISASSEMBLY
1. Remove the snap ring, and take out the retaining plate, drive plates, driven plates, and dish plate.
2. Using the COMPRESSOR (398673600), INSTALLER (398177700) and PLIER (399893600), remove the snap ring and take out the spring retainer and springs.
3. Take out the piston by applying compressed air.

INSPECTION
1. Drive plate facing for wear and damage
2. Snap ring for wear, return spring for breakage or setting, and spring retainer for deformation
3. Lip seal and lathe cut seal ring for damage
4. Piston check ball for operation

ASSEMBLY
1. Using the same special tools as those used in disassembling, assemble piston the return springs, spring retainer and snap ring.
2. Install the driven plate (thin), drive plates, driven plates, and retaining plate in that order. Then attach the snap ring.
3. Checking operation:
- Apply compressed air intermittently to the oil hole, and check the reverse clutch for smooth operation.

4. Measuring clearance (Retaining plate selection).
- Standard value: 0.5-0.8 mm (0.020-0.031 in)
- Allowable limit: 1.2 mm (0.047 in)

Before measuring clearance, place the same thickness of shim on both sides to prevent retaining plate from tilting.
