I've got the fork and headset off and was inspecting the races, it seems like the lower cup is loose in the head tube, that is it jiggles a bit when i press side to side on it. I am not too sure what keeps these things in place, do they just fit tighly in there? They aren't threaded in there? Park Tool only has instructions on how to overhaul and adjust headsets, I couldn't find any info on initial installation. I was looking through Barnett's chapter on headsets and they suggested loctite as a possible solution for a loose race. I am guessing I probably need a specific tool to remove the race, but can it be done with an adjustable wrench? I might be getting pretty close to the point where I take this into the bike shop, still I'd like to know what my options are.
