Inspection
1.
Remove any nicks and burrs from all motor compo-
nents with emery cloth.
CAUTION
Use eye protection such as goggles when using
compressed air.
Figure 69
2.
Clean all motor components with solvent. Dry all
parts with compressed air.
3.
Inspect drive gear, idler gear and bearing blocks
(Fig. 70) for the following:
1
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.
2
B. Gear teeth should be free of excessive scoring
and wear. Any broken or nicked gear teeth must be
replaced.
3
C. Inspect gear face edge for sharpness. Sharp
edges of gears will mill into bearing blocks and, thus,
must be replaced.
D. Bearing areas of bearing blocks should not have
excessive wear or scoring.
3
E. Face of bearing blocks that are in contact with
gears should be free of wear, roughness or scoring.
