DISASSEMBLY

Fig. 267:

1. Remove ring gear from planetary gear (Fig. 268).
2. Remove front bearing and the two races from ring gear (Fig. 268).
3. Remove tabbed thrust race from planetary gear (Fig. 268).
4. Remove snap ring attaching planetary gear to shaft and remove gear.
5. Remove rear bearing and race from planetary gear.
6. Measure inside diameter of ring gear bushing. Maximum allowable diameter is 24.08 mm (0.9480 inch). Replace ring gear if bushing inside diameter is greater than specified.
7. Check condition of planetary gear. Replace gear if teeth are worn, pins are loose, or carrier is cracked, distorted, or worn.
