9.. Insert the new bearing into the bearing-block so
when the bearing block is installed in the sander, the
grease fitting is facing forward and the set screws
and hub are on the right-side of the bearing housing
(see Figures.61.and.62).
10.. Slide (DO.NOT hammer) the bearing block and
bearing onto the drum shaft.
11.. Lower the drum and bearing-block onto the mounting
studs, and install the flat washers and the nuts.
Tighten the nuts in an alternating pattern until snug.
12.. Install and tighten the set screws.
13.. Wipe the grease fitting clean, and lubricate the
bearing with just enough grease to slightly seep from
the dust seal and wipe clean (these bearings are not
pre-lubricated). DO NOT over-grease.
14.. Repeat Steps 3—13 on all other bearings that need
replacement. Always replace both bearings on the
same drum.
15.. Adjust the drum and pressure rollers as outlined in
this manual.
7.. Remove any metal or abrasives trapped in the bearing
grease groove and grease port, or contaminants will
be pumped into the new bearing when you lubricate
it, causing bearing failure ( Figure.61).
8.. Clean and inspect the bearing-block for cracks, burrs,
wear, and other damage; replace/repair as required.
The “bearing race” should rotate inside of the
“bearing block” smoothly. If the race is loose or
wobbles inside of the bearing block, replace the
bearing block.
