Front Planetary Gear

Disassembly & Inspection

Remove thrust bearings and races from planetary gear and front planetary ring gear. Note direction of race installation. Measure front planetary ring gear bushing inside diameter. Replace planetary ring gear if bushing diameter exceeds .948" (24.08 mm). Measure planetary pinion gear thrust clearance. Clearance should be .008.024" (.20-.61 mm). Maximum clearance is .039" (1.00 mm). If clearance is not within specifications, replace planetary gear assembly.


Coat thrust bearings and races with petroleum jelly. Install thrust bearings and races, ensuring tabs on race align with planetary gear. Install races in planetary ring gear and planetary gear with the flat side against the gear surface. See Fig. 40.
