side of the thrust plates before removing. Also,
identify thrust plates (front and rear) with a marker
for proper assembly.

surfaces as residue on hands may be corrosive to
gear finish.

compressed air.
2. Clean all parts with solvent. Dry all parts with com-
pressed air.
3. Inspect drive gears and idler gears for the following
(Fig. 62):
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 indi-
cates need for replacement.

and wear. Any broken or nicked gear teeth must be
replaced.

must be replaced.

scoring.
B. Face of wear plates that are in contact with gears
should be free of wear, roughness or scoring.
C. Thickness of wear plates should be equal.
