Drum belt broke

Lifted top lid of cabinet using putty knife to release clips then removed front panel. Removed drum from unit and set aside. Found that one of the drum support roller wheels had lost the rubber roller. Removed old roller and secured new one which was an easy fix.
Installing the drum belt was a bit more difficult as I had to do it alone. I threaded the belt through the pulley/control arm and held it taugt with one hand and then inched the belt around the drum while holding it in place with my knees. Took awhile but I got it secured. Would definitely help to remove one of the side panels of dryer or have someone assist you.
