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 60.

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. See Figure 61.

NOTICE

Make sure the bearing grease hole in the bearing lines up with the grease groove in the bearing block and that no obstructions prevent bearing lubrication.

9.Insert the new bearing into the bearing-block so when the bearing block is installed in the sander, the grease zerk is facing forward and the set screws and hub are on the right-side of the bearing housing. See Figures 57 and 61.

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 zerk 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 through 13 on all other bearings that need replacement. Always replace both bearings on the same drum.

15.Adjust the Drums and Pressure Rollers as outlined in the Adjustments section, on

Page 14.
