mid-80s Centurion headset service
In stripping and servicing an early/mid-80s Centurion Elite (Tange CrMo frame), I undid the fork and headset cups. The lower, crown cup had a broken rubber o-ring for which I found an acceptable replacement. I re-greased and put the bearings back in, but I realized as I did so that both the crown race cup and the headset cup came out of the frame easily. There was some pitting on the outsides of the cups, but nothing inside. I was able to just slide the cups back in. This bike was not well-cared for, and there is some rust on many of the small parts, but the paint on the frame is in good condition.
My question for youse is whether I should worry about the fact that the cups for the headset and crown race just slide back into the frame, without requiring any headset press? It's my understanding that there should be some force required to push them in. Also, when tightening the adjusting washers/nuts, I've found that the races themselves turn and slide within the frame, rather than remaining in place.
Should I be replacing this headset? Or can I get by with just tightening the headset enough for the cups not to slide about?
