Christine- Go to the old woodworking machines site
www.owwm.com . I'm reasonably certain that you can download a parts diagram from that site as I did same when I bought a Sears belt driven 8"x48" belt sander, that wasn't working, at a garage sale . All it took eas a little disassembly and cleaning, and it works great. I found book/parts list at above site. If your motor is shot, you can use any old motor of the same rating to run the saw. Ron.
