place the puller arms next to the inner bearing
race. See Figure 69.

the shaft. Use a brass or aluminum rod between
the hammer and shaft (Figure 70).
Make sure to support both bearing races with
wood blocks.
3. The most ideal method of bearing removal is
with a hydraulic hand press. However, certain
procedures must be followed or damage may
occur to the bearing, shaft or case half. Note the
following when using a press:
a. Always support the inner and outer bearing
races with a suitably sized wood or alumi-
num ring (Figure 71). If only the outer race
is supported, the balls and/or the inner race
will be damaged.
b. Always make sure the press ram (Figure
71) aligns with the center of the shaft. If the
ram is not centered, it may damage the
bearing and/or shaft.
c. The moment the shaft is free of the bearing,
it will drop to the floor. Secure or hold the
shaft to prevent it from falling.
Bearing Installation
1. If installing a bearing in a housing, pressure
must be applied to the outer bearing race (Figure
72). If installing a bearing on a shaft, pressure
must be applied to the inner bearing race (Figure
73).
2. If installing a bearing as described in Step 1,
some type of driver will be required. Never strike
the bearing directly with a hammer or the bearing
will be damaged. If installing a bearing, a piece
of pipe or a socket with an outer diameter that
matches the bearing race will be required. Fig-
ure 7 4 shows the correct way to use a socket and
hammer when installing a bearing.
3. Step 1 describes how to install a bearing in a
case half and over a shaft. However, when install-
ing over a shaft and into a housing at the same
time, a snug fit will be required for both outer
and inner bearing races. In this situation, a spacer
must be installed underneath the driver tool so
that pressure is applied evenly across both races.
