To check for roughness or bearing binding, rotate bearings by hand and inspect the
balls. If the bearing balls are discolored or rotating them is rough, replace the
bearings.
Bearing tolerances provide tight fit of the bearings onto the pump shaft as well as a
snug fit in the bearing housing. The bearing housing, the bearings or the shaft
should be replaced if adequate bearing fit is not maintained.
If the bearings need to be replaced, take off the outboard bearing snap ring, and
press the bearings from the shaft or use a bearing puller instead.
G. DISASSEMBLY OF THE TWO-PIECE BEARING HOUSING
NOTE:
The two-piece bearing housing comes assembled from the factory and
should not require disassembly. If disassembly is necessary, the following
applies.
Remove the bolts holding the inner and outer sections of the two-piece bearing
housing together (See Figure 5). Use a thin wedge (i.e. common putty knife) to
separate the inner and outer bearing housing halves taking care not to damage the
mating surfaces. Replace the O-ring as needed.
