rosion. Remove burrs that can be removed without
changing dimensional characteristics. Inspect
tapped holes for thread damage. If the housing is
defective in these areas, discard the housing assem-
bly.
20. If the housing (18) assembly has passed inspection
to this point, inspect the housing bearings/bushings
(19) and (13) and if they are captured in the housing
cavity the two thrust washers (14) and thrust bearing
(15). The bearing rollers must be firmly retained in
the bearing cages, but must rotate and orbit freely.
All rollers and thrust washers must be free of brinel-
ling and corrosion. The bushing (19) or (13) to cou-
pling shaft diameter clearance must not exceed
0.010 inch (0.025 mm). A bearing, bushing, or thrust
washer that does not pass inspection must be
replaced. If the housing has passed this inspection
the disassembly of the motor is completed.
NOTE: The depth or location of bearing/bushing (13) in rela-
tion to the housing wear plate surface and the depth
or location of bearing/bushing (19) in relation to the
beginning of bearing/bushing counter bore should be
measured and noted before removing the bearings/
bushings. This will facilitate the correct reassembly
of new bearings/bushings.
