replacing bearings on hotpoint aquarius 1000 wm24?

hardest part is removing nut on spider wheel,once this is off please advise on next task.i've done bearings on older models but this one is getting the better of me.once nut and spider are off how does drum be removed to get bearings out?i guess the clips on the inner drum should be removed before it comes out,but how?if anyone can offer step by step guide on replacing bearings for this model then i would be most grateful
