I replaced rear roller drum wheels; one wheel did not turn anymore and over the years the drum wore a good size flat spot by shaving off the rubber surface. While I had everything apart, I decided to also replace the drum belt and clean all parts/surfaces inside.
This repair took a little longer due to the stuck wheel. I am a woman 76 yrs. of age and the wheel took a bit longer to get it to come off. Drum easy to remove.
