The procedure should be broadly similar to that for the WM63. Check out the answer to that one on this site. You've got to have a good selection of tools, particularly for forcing the old bearings out and the new ones in. It does help to dismantle as much of the machine as you can...it's all very straightforward to take apart. Be careful when you take wires off.....label them up first with a bit masking tape or something so you know where they go. You'll find the big nut at the rear of the drum is tight...you should find it behind an inspection panel, I think, at the back. Needs a very big socket. I repeat my warning at the beginning.... you do need a good assortment of tools to remove the old bearings. Best of luck!
