Overdrive Planetary Gears

Overdrive Planetary Gears

Disassembly

1. 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. Check the pins and shafts in the planetary assemblies for loose fit and/or complete disengagement. Install a new planetary assembly if necessary.





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





3. Inspect the overdrive one-way clutch inner race and the inner and outer races for scored or damaged surface areas where the rollers contact the races.





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





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

Remove the coast clutch-to-overdrive carrier adapter.





6. Remove and inspect the overdrive sun gear.





7. CAUTION: Do not attempt to remove the No. 12 bearing from behind the pinion gears or transmission damage can occur.

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 No. 2 overdrive planetary thrust bearing in place.

Install the No. 2 overdrive planetary thrust bearing.





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





3. NOTE: 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.





4. NOTE: Adapter part number must not be visible after installation.

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

Install the coast clutch-to-overdrive carrier adapter.
