a. Inspection
(1) Visually inspect the planetary carrier as-
sembly for evidence of excessive wear, indications of
overheating, damage, or heavy metal contamination.
(2) Check the end play of the planetary
carrier pinions. With the washer held flat, insert a
feeler gauge between the carrier and thrust washer.
End play must be within 0.008–0.031 inch (0.20–
0.79 mm).
NOTE:
• Do not disassemble the carrier assembly unless
parts replacement is necessary. Failure of one pin-
ion requires replacement of the entire matched
pinion gear set, pinion pins, and bearings.
• Depending upon the amount of labor (machining
the bushing), time, part replacement, and extent
of rework, complete replacement of the assembly
may be more practical.
