I installed a 1/4-28 straight zerk fitting in one of the holes of the upper sander drum. It required drilling it out to 1/2 inch (to fit socket to tighten zerk) then drilling with a 7/32 drill and tapping with 1/4-28 tap. Then I milled the bottom of the hole flat so I could get a good grip with the short zerk fitting.
Now I can grease the improved needle bearing races on the upper idler drum of the belt sander. To access for maintenance, all you have to do is remove the sanding belt.
