REAR PLANETARY GEAR INSPECTION

1. Using a dial indicator, measure the inner diameter of the rear planetary gear bushings.

Rear planetary gear bushing inner diameter

Front side: 33.26 - 33.286 mm {1.3095 - 1.3104 in}

Rear side: 33.26 - 33.286 mm {1.3095 - 1.3104 in}



If it exceeds the specification, replace the rear planetary gear component with a new one.



When the rear planetary gear component is replaced, inspect the contact surface opposed to the
planetary sun gear.
