7) Checking clearance:
Forward clutch
Standard value:
0.45—0.85 mm (0.0177—0.0335 in)
Allowable limit:
1.6 mm (0.063 in)
Overrunning clutch
Standard value:
1.0—1.4 mm (0.039—0.055 in)
Allowable limit:
2.0 mm (0.079 in)
NOTE:
Before measuring clearance, place the same thickness of
shim on both sides to prevent retaining plate from tilting.
If the clearance is out of the specified range, select a
proper retaining plate so that the standard clearance can
be obtained.
