This is damned frustrating...
I'm rebuilding my 'cross bike with Campy Centaur components. I've stripped everything, but I can't seem to get the bottom bracket to budge. It's a Shimano UN52, and when I tried to loosen the drive side BB cup [English thread, loosen clockwise], it just doesn't move. How stuck is it? I tried with the torque wrench and I torque a whole lot higher than the 70nM it was supposed to be tightened to. I tried pouring hot water over the BB shell -- nothing... I don't want to force it or break anything, but I'm at wit's end here. This should not be this difficult. In fact, the left cup comes off pretty easily.
Any ideas? I'll even accept ideas that result in the destruction of the BB; I was planning to use it on another bike, but I'd be happy to get another, if necessary.
One more thing... am I right that the cups on the BB-UN52 are plastic?
