gear, idler gear, and bearing blocks. Carefully assemble
bearing blocks and gears noting identification marks
made during disassembly.
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-

6. Position the motor body on its side. Carefully slide
bearing block and gear assembly into the body cavity
using identification marks made during disassembly.

and wear. Any broken or nicked gear teeth must be
replaced.
7. Remove any excess lubrication from mating sur-
faces of body, rear cover, and front flange. Make sure
that these surfaces are clean and dry.
C. Inspect gear face edge for sharpness. Sharp
edges of gears will mill into bearing blocks and, thus,
must be replaced.
