Note the following when removing
bearings:
1. When using a puller to remove a
bearing from a shaft, take care that
the shaft is not damaged. Always
place a piece of metal between the
end of the shaft and the puller
screw. In addition, place the puller
arms next to the inner bearing race.
See Figure 40.
2. When using a hammer to remove a
bearing from a shaft, do not strike
the hammer directly against the
shaft. Instead, use a brass or
aluminum rod between the hammer
and shaft (Figure 41) and make
sure to support both bearing races
with wooden blocks as shown.
3. The ideal method of bearing
removal is with a hydraulic press.
Note the following when using a
press:
• Always support the inner and
outer bearing races with a
suitable size wooden or
aluminum spacer (Figure
42). If only the outer race is
supported, pressure applied
against the balls and/or the
inner race will damage them.
• Always make sure the press
arm (Figure 42) aligns with
the center of the shaft. If the
arm is not centered, it may
damage the bearing and/or
shaft.
• The moment the shaft is free
of the bearing. It drops to the
floor. Secure or hold the
shaft to prevent it from
falling.
