Why won't the Bottom Bracket Cartridge thread all the way?
1988 Trek 360 road frame, True Temper. 1.37 X 24 is stamped on the bb cups I removed (Hatte?). Shell is 68mm and bb is 113mm. So I have a newly purchased Shimano UN55, 68 X 113, 1.37 X 24. Goes in drive side and counterclockwise threading. But I can only get about 5 turns and it stops, even cranking hard. Half of the threads are sticking out.
Yet, the removed bb cup and be rethreaded with no problema. I don't believe there are any protrusions in the shell.
