shaft.

3. Carefully inspect seating surface and threads of
bearing lock nuts. Replace lock nut if any damage is
found.
4. Loosely secure roller assembly in bench vise and
lightly tap one end of roller shaft until seal and bearing
are removed from roller cavity. Remove second seal and
bearing from roller cavity by tapping on shaft.
5. Clean bearing cavity in roller and remove any rust
with crocus cloth.
Assembly
1. Place roller shaft into roller.
Note: If bearing lock nuts are being replaced, use
original lock nuts for assembly purposes, if possible.

nuts. Use the new nuts only after new bearings and
seals have been installed.
