Derailler claw bent and stuck
I'm having a problem with an old SunTour V-GT Luxe derailleur I just got for one of my vintage bikes. I noticed the claw was bent so instead of trying to mess with it, I ordered a new claw for it. Unfortunately when I tried to replace it this morning the claw will not come off. I put it in a vice and tried with all my strength to remove it, but no-go.
Now the claw isn't bent much - just enough to worry me that it might cause problems shifting. I can keep trying to remove it, but I'm worried that the nut and the allen key hole might take some serious damage if I really pull out all the stops in trying to get it out. On the other hand, if I try to bend it back, I worry about metal fatigue from re-bending the claw and potentially missing and hitting the derailleur (not that I think I would do that, but I guess it's possible). So what do I do? Do I keep trying to remove it, or do I try to hammer it back into shape?
Right now I'm thinking of hammering it. The claw looks like stainless steel, so I don't think it would lose strength or become brittle from a little re-bending.
What do you guys think?
