The installation took me about two hours, but was otherwise relatively simple. Everything bit by bit with the screwdriver, unscrew what is in the way: cover, right side panel, bracing with Kupferbürstchen, rear panels, pump, drum suspension, drum, and finally the lower front cover where the drive shaft goes in. When the fan fastened there with a socket wrench (with a second, hold steady on the shaft itself) triggers, you can drüberpfriemeln the belt. The V-belt is tensioned by a spring on the engine block. This solved first. Pull belt over the drum and hook. Then reassemble it, last stretch up to the side wall, the belt and screw.
