Im adept with a mallet! - but it cant knock in what is already in- I cant get on the back side of the bearings? the spacer is making it an almost smooth axel-way- that I cant get purchase on anything to whack 'em out. Ive never had a 400 hub apart- in fact this isnt mine, its my Bros- he brought the wheels from someone up 't North who siad they were rebuilt, new rims, stainless spokes etc- but theres no spacer fitted! So we decided to take his old wheel apart- got the retainer out, then where faced with two closed doors, so to speak. Im sure you dont have to muller one of the bearings, to get at the spacer and the back of the other?
