COMPONENTS

DISASSEMBLY OF NO.1 ONE-WAY CLUTCH AND SUN GEAR




1. CHECK OPERATION OF NO.1 ONE-WAY CLUTCH
Hold the sun gear and turn the hub. The hub should turn freely clockwise and should lock counterclockwise.




2. REMOVE NO.1 ONE-WAY CLUTCH FROM SUN GEAR
While turning the hub clockwise, remove the No.1 one- way clutch from the sun gear.




3. REMOVE THRUST WASHER FROM SUN GEAR INPUT DRUM




4. REMOVE SUN GEAR FROM DRUM
a. Using snap ring pliers, remove the snap ring from the drum.
b. Remove the sun gear from the drum.




5. CHECK SUN GEAR BUSHINGS
Using a dial indicator, measure the inside diameter of the sun gear bushings.

Maximum inside diameter: 22.59 mm (0.8894 in.)

If the inside diameter is greater than the maximum, replace the sun gear.

ASSEMBLY OF NO.1 ONE-WAY CLUTCH AND SUN GEAR




1. INSTALL SUN GEAR TO DRUM

INSPECTION OF FRONT PLANETARY GEAR




MEASURE PLANETARY PINION GEAR THRUST CLEARANCE
Using a feeler gauge, measure the planetary pinion gear thrust clearance.

Standard clearance: 0.16 - 0.56 mm (0.0063 - 0.0220 in.)

Maximum clearance: 0.61 mm (0.0240 in.)

If the clearance is greater than the maximum, replace the planetary gear assembly.
