Overdrive Planetary Gears: Disassembly

CAUTION: New planetary gears must be installed. Do not restake the originals.

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

Fig 1: Identifying Shaft Retaining Pins

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