Does anyone know how we can do this ourself as we are really struggling to get the belt back on we need it done as our one son is incontinent so a lot of bedding is piling up, we have tried from motor to drum and it won't reach we have the part but it seems too short any help would be gladly appreciated Neither drum nor motor seem to move enough for us to navigate the belt on and there is no lip on drum to keep the belt on while we turn motor
