Installing the New Spindle and Bearings

Use the following tips when installing the bearings.

• Place the bearing square against the housing and

manually hand press the bearings into the housing.

• Make sure the spindle housing is clean from grease

or any other debris.

• If the bearings are mechanically pressed into the

spindle housing, support both the inner and outer parts of the bearing with a flat surface.

• Do not use a hammer to assemble the bearings. This

can damage the bearings.

• Do not use the spindle shaft, pulley and nut to install

the bearings. This will apply pressure only on the inner part of the bearing.
