Remove the rear disc, unstake the nut, and then remove, it's a 32mm A/F socket size.

Retrieve the large washer, then if you are lucky, the whole bearing will slide off the stub axle.

Sometimes the inboard inner bearing race will remain stuck to the stub axle, if this happens, make a cut using an angle grinder almost through the bearign race, and while you are still wearing your goggles, use a sharp cold chisel to fracture the remains of the bearing.
The stub axle in either case should be cleaned with fine (400) wet and dry paper, then very lightly greased before the new bearing is fitted.

Hope this helps

Brian
