3. Inspect drive gears and idler gears for the following
A. Gear shafts should be free of rough surfaces and excessive wear at
bushing points and sealing areas. Scoring, rough surfaces or wear on
gear shafts indicates need for replacement.

nicked gear teeth indicate a need for motor replacement.

thrust plates and, thus, must be replaced.
