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 (O/D) One-Way Clutch (OWC) 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 O/D planetary thrust bearing on the nose of the O/D planetary gear carrier assembly.





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

Remove the coast clutch-to-O/D carrier adapter.





6. Remove and inspect the O/D sun gear.





7. NOTICE: 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 O/D planetary thrust bearing in place.

Install the No. 2 O/D planetary thrust bearing.





2. Install the O/D planetary gear carrier into the center shaft and O/D.





3. NOTE: Make sure that the No. 12 bearing is in place in the O/D planetary prior to installing the O/D sun gear.

Install the O/D 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-O/D carrier adapter.
