Hi , yes it is a big job , firstly both the drums have to removed from the machine then split and the inner drum removed from the outer drum , but before this all the electrice via the drum have to be undone then the heater has to be removed so not to damage it , then the bearings have to be removed using the correct tools . as both bearings are of differant sizes , when they have been replaced the drums have to be put back together then the heater has to be put back in and then the drum put back in the machine and then all the electrics put back on the drum in the correct order . still want to attemp it ? hope this helps
