I reassembled the (cup and cone) bottom bracket on my 1987 Peugeot Iseran yesterday, and tried adjusting it per Sheldon Brown's instructions. Exactly what he said happens - if I tighten the adjustable cup even a couple of degrees - the bracket starts binding. If I back it off, I have quite a bit of lateral play.
So, my question is how much later play is too much? Here are a couple of quick videos that hopefully show what I have going on.
*** I promise I did not shoot a vertical video, the iPhone just decided that I did on it's own ... sorry 'bout that.
Second question - I read that there is a torque spec on the crank bolts (that attach the cranks to the BB) - but I can't find what that is. Any suggestions?
