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. Use a new planetary assembly if either of the following conditions exist. Check the pins and shafts in the planetary assemblies for loose fit and/or complete disengagement.





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





3. Inspect the front One-Way Clutch (OWC) inner race for scoring. If the front OWC inner race is scored or damaged, install a new front planetary gear, center shaft and OWC.





4. Inspect the inner and outer races for scored or damaged surface areas where the rollers contact the races.

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