Belfast, sorry mate - I am here but i'd left ansafon on cos I'm antisocial & i was watching a video of Jerez - didn't know it was you or i'd've picked up.
The bearings can be drifted out. The first one's always a bit of a pig. I have a selection of long bolts,tubes etc that I use (with a big hammer) - gotta find something that'll get a purchase on the bearing inner. You can only get a slight edge so it's a bit tricky. If you wedge the drift at an angle against the other bearing with a piece of wood so's it can't slip sideways you should be able to get a good whack on it. Work it all around. Support the wheel firmly on lumps of wood or something. I didn't heat mine, but I once used towels soaked in boiling water to warm up a hub to get bearings in.
I remember someone here I think talked of making a simple tool to get wheel bearings out, it sounded like a good idea but I forget the details, who, where & what...?
I'm here now if you wanna chat or I'm in all day tomorrow.
Best, KB
