Reverse Clutch

A: DISASSEMBLY





1. Remove the snap ring (12), and take out the retaining plate (11), drive plates (10), driven plates (9), and dish plate (8).
2. Using the Special Service Tool(SST)1, (SST)2 and SST3, remove the snap ring (7) and take out the spring retainer (6) and springs (5).
SST1 398673600 COMPRESSOR
SST2 398177700 INSTALLER
SST3 399893600 PLIERS
3. Take out the piston (3) by applying compressed air.

B: 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

C: ASSEMBLY





1. Using the SST1, SST2 and SST3 as those used in disassembling, assemble piston (3) the springs (5), spring retainer (6) and snap ring (7).

2. Assemble the dish plate (8), driven plates (9), drive plates (10) and retaining plate (11) in that order and attach the snap ring (12).

NOTE: Pay attention to the orientation of the dish plate.

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 inch)
Allowable limit.
1.2 mm (0.047 inch)

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