I'm rebuilding my 1974 Raleigh International from equipment I've acquired from countless horse trades and other sources. I go an Ultegra 6603 crankset for free as a local bike shop was throwing it out. It had been in a bad collision, and the large and middle chainrings were destroyed. I replaced those with new chainrings. I just bought and installed a new BB60, and I installed one of these before but I can't remember how. I bought the appropriate Park tool to install the bearings. The BB unit came with a plastic ring with internal and external splines. The ring doesn't grab the cups all that hard, and getting purchase on the ring with the Park tool is even harder. Does this unit really not to be tightened down very hard? I imagine that is the case, but I want to check. I couldn't resist using a big channel lock, and I don't mind that I gouged the cups a bit, but what is the normal procedure. I feel fairly sure I'm safe and have only done a little cosmetic damage. And if the cups are tighter than they need to be, I figure no harm done.

I haven't been able to acquire the proper crank fixing bolt for then on drive crank. I understand I'm supposed to preload the arm on the spindle before tightening the cinch bolts, but it really feels I tapped it on well. Since little or no tension is expected on that bolt, am I taking a risk going without it?
