I found the diagrams at the listed site below and also at Searspartsdirect.com. The parts were not available at the pcappliancerepair.com site. However I found three Sprocket and bearing kits for $23.55 at http://www.a-1appliance.com. The part number had changed from B-115547 to 416-1449. They had not sold any for 9 years. I did not check Sears to see if they had them.
