IMPORTANT: Mark the relative positions of the gear teeth and the bearing blocks so they can be re- assembled in the same position. Do not touch the gear surfaces as residue on hands may be corrosive to gear finish.
8.Place the motor on its side and push on the rear bear- ing block to remove the bearing block and gear set (Fig. 82).
9.Carefully remove and discard
IMPORTANT: Make sure not to damage the counter bore when removing the shaft seal from the front plate.
10.Position front flange with seal side up. Remove shaft seal.
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.
2.Clean all motor components with solvent. Dry all parts with compressed air.
3.Inspect drive gear, idler gear and bearing blocks (Fig. 84) 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 indi- cates need for replacement.
B.Gear teeth should be free of excessive scoring and wear. Any broken or nicked gear teeth must be replaced.
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.
E.Face of bearing blocks that are in contact with gears should be free of wear, roughness or scoring.
4.Inspect front flange and rear cover for damage or wear.
