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 in)
Allowable limit:
1.2 mm (0.047 in)
NOTE:
Before measuring clearance, place the same thickness of
