Bearing Replacement

Detaching bearing from housing.
6. Re-attach the sanding head cover before
operating the sander.
3. Once the old bearing is removed, clean the
bearing housing. Insert the new bearing into
the notches in the housing as shown in
Figure 19. Twist the bearing clockwise 90°
after it reaches into the housing as far as it
will go as shown in
Figure 20.
4. Insert the screwdriver through the bearing,
as in
step 2 and lever the bearing into its
proper position in the housing.
5. Press or tap the bearing and housing back
into place on the drum shaft. Re-adjust the
drum as necessary.
The tools necessary for this job are a large round
shaft screwdriver and a bench vise. Replace
bearing as follows:
1. Remove the roller housing from the drum
sander and clamp it tightly in a bench vise.
2. Insert the screwdriver into the center hole of
the bearing as shown in
Figure 18. Lever the
bearing until it turns perpendicular to the
housing. Once the bearing is turned 90° from
the housing, it should slide free with little
effort. The housing is designed with notches
that allow the bearing to be inserted and
removed. It is important that you lever the
bearing so it turns in alignment to those
notches.

NOTICE
Lubricate the bearings sparingly after about
two months of sander operation. The bear-
ing requires very little grease, so avoid the
temptation to over-lubricate.
NOTICE
Make sure, when installing the new bearing,
that the lubrication groove in the bearing
will match the groove and grease fitting in
the housing once it is in place.
