Removal of Bearings:

Most bearings for these pumps were designed to have a light press fit into the front and rear housings.
Removal is generally accomplished by destroying the bearings. The bearings can be pulled out using a
hooked tool (see Photos 12a and 12b). Plastic bearings, such as Teflon, can also be extracted by using a
tap that is slightly larger than the bearing inner diameter (see Photo 12c).

CAUTION! Be careful not to damage the housing bores when removing the bearings.
