Do not damage the end of the shaft.

Sleeve Bearings
a) After the bearing shells have been removed, a bearing puller, such as shown above should be
used to remove the ball bearing.
b) The puller bar must be "square" with the end of the shaft at all times and the puller screw
should be tightened steadily to enable the bearing to slide smoothly off the shaft. Do not dam-
age the end of the shaft.
3.
After the bearings have been removed, they should be wrapped in dean paper or cloth to prevent
contamination. Other parts which surround the bearings, such as bearing housings, should be kept
clean in the same manner.
6.1.5 Install the Ball Bearings
NOTICE:
There are several methods used to install bearings. The recommended method is to use an
induction heater that heats as well as demagnetizes the bearings. Failure to use this method
may result in equipment damage.
1.
A film of clean machine oil should be applied to the bearing seat on the shaft.
2.
The bearing should be started on the shaft by tapping the inner race with a hammer or mallet. Do
not use a lead mall. The bearing must be kept "square" at all times.
3.
Once the bearing is located on the shaft, a driving sleeve, such as the one shown below should be
used. The sleeve should contact the inner race of the bearing only. The bearing should be pressed
or driven until it contacts shoulder "x".
