Installation
1. When installing a bearing in a
housing, apply pressure to the outer
bearing race (Figure 43).
When installing a bearing on a
shaft, apply pressure to the inner
bearing race (Figure 44).
2. When installing a bearing as
described in Step 1, some type of
driver is required. Never strike the
bearing directly with a hammer or it
will damage the bearing. When
installing a bearing, use a piece of
pipe or a driver with a diameter that
matches the bearing inner race.
Figure 45 Shows the correct way to
use a driver and hammer to install a
bearing.

Shows the correct way to use a
driver and hammer to install a bearing.
3. Step 1 describes how to install a
bearing in a case half or over a
shaft, However, when installing a
bearing over a shaft and into the
housing at the same time, a tight fit
is required for both outer and inner
bearing races. In this situation,
install a spacer underneath the
driver tool so that pressure is
applied evenly across both races.
See Figure 46. If the outer race is
not supported as shown, the balls
will push against the outer bearing
race and damage it.
