Maxi Car front hub - past the point of no return?

[Smut Pedaller]

Yeah I was thinking maybe this might work? There is bugger all of a gap behind the cups, maybe 2mm or so, but since there is a gap I guess that means they are meant to be removeable in some way...? Also I guess some heat may help as I figure the alloy hub would expand more than the steel cup...

both as drawn and in your photo the gap at the rear looks less than 1mm. A commercial bearing puller will have much larger lips on it than that, and there is usually an implicit assumption with such things that there is a clear centre bore of some kind, not much smaller than the collet. Both ways round that approach is not going to work in this case.

Bearing cups can be fantastically tight in hubshells (even if they are not meant to be) and yes some warmth will help. But don't overdo it; the aluminium hubshell may well start to lose strength permanently if you overdo it.

I have used a burr grinder to excavate the hubshell behind cups so that they can be removed but TBH using the welder is much, much easier in cases like this.

Thanks for the tips. I think at this point in time I'll try the grinding paste method to get the hub running a bit more smoothly and then replace the bearings, however I think anything more is more hassle than just buying a new hub and respacing it to suit the fork.
