I was out of the country when the damage occurred but based on my wife's description I knew what had happened. Upon returning to the 1st World, i verified a totally free-spinning drum and ordered a full rebuild kit (rollers, belt & idler). The instruction video was very helpful - especially in listing every single tool needed so i only made one trip to the workshop and brought up exactly what i needed, the first time. Everything went pretty much according to the instructions except that holding the drum in place while retrieving and installing the front panel wasn't so seamless. Also, getting the belt around the tensioner and onto the motor pulley required more effort than anticipated - wished the tensioner has a hold-down screw just to keep it in place during assembly. The top lid fell closed a couple of times (mostly due to my constricted laundry room environment) and the drum needed to be held tightly against/over the rear felts (one hand) while the rather sharp, awkward and heavy front panel was positioned and pulled up (two hands). If you're counting that's three hands so i had to enlist the help of a support block (paint stirring stick) until i was ready to make the final fit-up). With the front on and top still open I rotated the drum to kick out the support and then bumped the machine over to watch it go round and round. Secured the lid and promptly did the six loads of laundry that had piled up.
Very glad i dd the whole kit as i discovered that the in-situ tensioner was a sliding-type, not a roller. I see this design lasting longer.
