Inspection

INSPECTION

Inspect each planetary carrier assembly for damage. Check that each pinion gear rotates freely and smoothly on its shaft. Check that the fixed thrust washer on each side of each pinion gear is in place. Check that the outer ends of the pinion shafts are not discolored from overheating. Replace the carrier assembly if jammed or sticky pinion gears, spun or missing fixed washers, or blackened pinion shafts are found.


Check sun gear and annulus gear condition. Replace components as necessary if damaged or if any bushings are scored or worn. The bushings are not serviceable. Replace the driving shell if worn, cracked or damaged.


Replace the output shaft if the machined surfaces are scored, pitted, or damaged in any way. Also replace the shaft if the splines are damaged, or exhibits cracks at any location.
