Overdrive Planetary Gears: Disassembly

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.
