Wow, thread necromancy squared! Rather apposite, in fact, as I've just, eight years on, replaced the bearings again, with the spare set that I bought last time round. For some reason, and remembering that (obviously) I had done it before, it was one of those really frustrating jobs where only Park Tools really benefit.
Everything went wrong. The old bearings wouldn't shift, and I over-hit the axle-end, with a track nut on it to spread the load. So the threads took a little damage. Then the new bearings wouldn't seat. I was using the old bearings and the track nuts in a make-shift press, and ended up with one track nut locked onto the axle. The usual trick of locking up two nuts on the other end wouldn't work, and I had to buy a Park Tools axle vice to free the nut up. That was just the last in a series of locked-up nuts that I did manage to free. I also bought a nylon support bush for the hub, to spread the load when tapping bearings in. I'm still not that happy with the result, the new bearings run a bit rough, and one cartridge (remembering that they're identical from the same purchase) seems to sit a bit proud compared to its predecessor. Took hours for a dud result, but it's a winter fixed so it will have to do
I replaced them in part because I'd creaked my way round one ACME event, and I knew that they were due for replacement, as was the BB cartridge. But, even after all that, I still creaked my way round the next
I think it was actually the cranks and chainring moving - even though they were no longer even on the same BB
Some jobs just seem doomed
