High Clutch

A: DISASSEMBLY





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

B: INSPECTION
1. Drive plate facing for wear and damage
2. Snap ring for wear, return spring for setting and breakage, and spring retainer for deformation
3. Lathe cut sea[ rings (large) (small) for damage
4. Piston check ball for smooth operation

C: ASSEMBLY





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

2. Install the driven plate (thinner) (7), drive plates (8), driven plates (thicker)(9), and retaining plate (10) in that order. Then attach the snap ring (11).
3. Checking operation:
Apply compressed air intermittently to the oil hole, and check the high clutch for smooth operation.





4. Measuring clearance (Retaining plate selection):

Standard value:
1.8 - 2.2 mm (0.071 - 0.087 inch)
Allowable limit.
2.6 mm (0.102 inch)

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