I am looking for are the two round drums that the sanding belt rides on at either end of the 6" belt sander Model #103.0803. I don't know what year it is, but it is an older model. When I start the belt sander you can hear a loud clicking noise while it is running. I started to look for the problem and found that the inserts that are in each end of the drum are loose. I feel at this point it is dangerous to use and want to replace those drums. Thanks, Bill

If you look at "Check out some similar questions", you will note that parts are no longer available from Sears. Looks like brass bushings or maybe "oilite" was used. A very good Ace hardware store or possibly on-line could help you.

Found this on eBay, hope it helps.
