+1 Very likely someone used loctite or some other bonding agent when it was intalled. I would leave it in unless you absolutely need to remove it. You can remove it using a torch but I would avoid doing this or get someone skilled in framework to do this since you run the risk of wrecking the paint or even damaging the BB frame if not done properly.
