Bearings, Gaskets, Seals and O-rings
Parts of this nature are frequently damaged during removal or disassem-
bly. In addition, they sometimes deteriorate or lose their effectiveness be-
cause of age or misuse. Replacing these parts whenever overhauling a
pump is a good policy.
Impeller Shafts
Examine shaft for severe scratches, grooves or corrosion - especially un-
der mechanical seals. If scratches are not severe, clean them with a fine-
cut file.
A CP-5 Series pump may be disassembled by removing the pump and
transmission together, and then disassembling the pump is usually the
easiest method. Refer to service parts list (SPL), available at
waterousco.com, for component identification.

Installing Ball Bearings
Most Waterous pumps are designed so that ball bearings fit tightly on their
shafts and have relatively loose fits in the bearing housings. When mount-
ing these bearings on shafts, always apply force to the inner races. When
bearings have a tight fit in the housings, and a heavy force is necessary to
install them, be sure to apply force only to the outer bearing races. For ei-
ther type of fit, applying force to the wrong bearing race may damage the
balls and race.
Installing Body Gaskets
To provide added sealing for gaskets between body halves, or between
bodies and intake adapters, coat both sides of these gaskets with a suita-
ble sealant. A compound such as Permatex Super 300 is recommended
for this application. Be sure all traces of previous gaskets and sealant are
removed before installing new gaskets.
