Campy Record 9 speed


I am about 2 miles from home and the chain starts to skip. I pull over and notice the bolt for the jockey wheel has become loose and luckily I didn't lose it. My question is this:

How do I prevent the bolt from doing this again? (locktite?)

If you tighten to much then the jockey wheel doesn't spin.

What a pain in the butt, I ended up riding home on big chainring and for some reason I was still having problems on the small chainring. On this bike, rarely can you spin the gears backwards, I believe the chain might have less than 2000 miles on it.
