3.3 Installing a bearing
Long bearing life is quite dependent on careful handling of the bearing when it is out of the housing and
during the installation procedure. Dirt and rough handling are prime enemies of precision bearings. Bear-
ings should be pressed, not "hammered" into place. If heat is used to facilitate the installation, a hot oil
bath is the best method. Bearings for grease lubrication should be hand-packed with grease to ensure
adequate lubrication at startup.
3.4 Normal bearing temperature
The running temperature for a bearing assembly depends on many factors such as speed, bearing
loads, ambient air temperature, and condition of bearings. Temperatures higher than the human hand
can tolerate are very satisfactory for good bearing operation and should not cause any alarm.
For a given speed and loading, the bearing housing temperature will stabilize at some temperature, usu-
ally below 200°F., which will be the normal temperature for that installation. Higher temperatures than
this normal temperature, without any change in speed or loading, can mean a lubrication difficulty or the
approach of a bearing failure.
3.5 Disassemble the Bearing Assembly
1. Disassemble the liquid end in accordance with the instructions for that section.
2. Remove the cap screws which fasten the retainers (109 and 119B) to the bearing housing and pull
the retainers off the shaft. Retainer (119B) will push the slinger (9905) off the shaft with it.
3. Remove the shaft (122) from the bearing frame (134C).
4. Press the bearings off the shaft by pushing against the inner race.
