  1. 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.
