I found at lonely looking Mastercraft 4x36" belt sander disc combo at a garage sale for $5. The guy said it was not working but I snatched it up anyway as I was thinking of what I could do with the aluminum wheels. The motor ran and the disc turned, but the belt on the top wasn't moving. Inside a cover on the back I found a cogged rubber belt from the motor to the sander wheel. The cogs were completely stripped off. After a little digging to locate a part number, I found Motion Industries had them in stock. Ask for a 150XL037 from Gates or suitable replacement. Should be under $10.
