Overdrive Planetary Gears

Overdrive Planetary Gears

Disassembly





1. CAUTION: New planetary gears must be installed. Do not restake them.

NOTE: Individual parts of the planetary carriers are not serviceable.

Before installing a planetary assembly, the shaft retaining pins should be checked for adequate staking. Use a new planetary assembly if either of the following conditions exist. Check the pins and shafts in the planetary assemblies for loose fit and or complete disengagement.





2. Inspect the pinion gears for damaged or excessively worn teeth, and for free rotation.





3. Inspect the front one-way clutch inner race for scoring. If the front one-way clutch inner race is scored or damaged installation of new front planetary gear, center shaft, and one-way will be needed.
4. Inspect the inner and outer races for scored or damaged surface areas where the rollers contact the races.





5. Remove and inspect the No. 2 overdrive planetary thrust bearing on the nose of the front planetary gear carrier assembly.





6. NOTE: Note the location of the part number stamped on the coast clutch adapter for assembly.

NOTE: Inspect the sun gear for damaged or worn teeth.

Remove the front sun gear.
1 Remove the coast clutch to overdrive carrier adapter.
2 Remove the front sun gear.





7. Inspect the No. 12 bearing for damage.

Assembly





1. NOTE: Thoroughly clean all parts and blow dry with moisture free compressed air.

NOTE: Use petroleum jelly to hold the overdrive planetary thrust bearing (No. 2) in place.

Install the No. 2 overdrive planetary thrust bearing.





2. Install the overdrive planetary gear carrier into the center shaft and front ring gear.





3. CAUTION: Make sure that the No. 12 bearing is in place in the overdrive planetary prior to installing the overdrive sun gear.

Install the overdrive sun gear with the recessed gear teeth facing toward the adapter.
