Help please!
I just bought a Peugeot frameset circa 1982-1985. It had a bottom bracket already installed, but no crankset. I stripped a crankset off an old Carrera road bike I had, a Prowheel Forged Gloria. I've taken the small ring off it so it's just a single 50t chainring.
Problem is, when fully tightened, it rubbed against the bottom bracket on the non-drive side due to the shape of the cup, which sticks out rather than hollows out. So I stripped that bottom bracket and am now trying to install the BB that came with the Carrera (CH 2J is the only info I have on the name of the BB).
The CH 2J fastens to within 3 or 4 turns of being fully fastened then completely seizes up. This is after degreasing and cleaning all threads with a toothbrush, then greasing them all up again.
Anyone have any ideas what the problem might be? I thought either the threads are gone, or not cut deep enough into the shell, but when I shine a torch through the other end I can see that they clearly are. Took it into a couple of LBSs who just said I'd need to buy a new BB or use a threadless one...
Cheers,
Tom
