Raised the front of top panel with the putty knife and the front panel was unscrewed as the video showed. The drum slid out after the belt was released.

My machine had 4 rollers, which was not shown in the schematics. So I replaced the back, cleaned the front ones and works great for now. Plan to replace the front later.

Removing the tri rings is much easier if cut w wire cutters. Otherwise waist lots of time to get them off. Just buy new ones.
