Do-It-Yourself Story

I searched YouTube to find a video on how to disassemble my particular model. I took a few pics of critical areas before disassembling. I kept screws near their holes with masking tape. One of the drum support rollers was in bad shape. I decided to replace both and also the corresponding axles plus the belt tension pulley. Parts arrived in two days. One of the axles could not be removed until I did further disassembly. The roller bearings are sleeve bearings and there's a debate online as to grease or not. I ended up greasing but wiping most of it off, a sort of compromise. If the new ones fail I'll grease more next time. I was able to reassemble without any significant issues. Problem resolved.
