Replacing Bearings
Figure 91. Detaching bearing from block.
4. Once old bearing is removed, clean bearing
housing. Insert new bearing into notches in
the housing (see
Figure 92). After it reaches
into housing as far as it will go, twist the bear-
ing clockwise 90° (see
Figure 93).
The Model G1066R/G1066Z/G1079R is designed
for many years of reliable service. But after long
periods of heavy use, it may be necessary to
replace the pillow block bearings. Always replace
both bearings on the same drum at the same time.

2. Remove bearing housing from drum sander
and clamp it tightly in a bench vise (see
Figure 91).
3. Insert screwdriver into center hole of bearing
(see
Figure 91). Lever bearing until it turns
perpendicular to the housing. Once bearing
is turned 90° to housing, it should slide free
with little effort. The housing is designed with
notches that allow bearing to be inserted and
removed. It is important that you lever bear-
ing so it turns in alignment to those notches.

Figure 93. Inserting bearing into housing.
Make sure, when installing the new bearing,
that lubrication groove in the bearing will
match groove and grease fitting in housing
once it is in place.
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.
5. Insert screwdriver through bearing, as in
Step 3 and lever the bearing into its proper
position in housing.
6. Press or tap bearing and housing back into
place on the drum shaft. Re-adjust the drum
as necessary.
