Question Rounded crank bolt, Any advice?

Does anyone know how much a shop might charge to pull the bolt off? well I will just have them finish the crank pulley job.

The socket slipped off and rounded the he'll out of the bolt,Now I can't move it.

try hammering on an old socket that's just slightly smaller than the original size.

What you could do is get a cutting wheel and cut a small groove into the head of the bolt. Then use a air hammer then see if you can spin it out I use that method on wheel lug nuts that have seized up . You really don't have any other way of getting it of cause it has been stripped out. You would have to take the crank out then ,but that would be a not so fun job.

Thanks for the suggestions guys. Unfortunatly I don't have any tools and a garage so any work(welding and air tools) would have to be on base(renting a stall). Might just take it somewhere. I am crunched for time going TDY and all so might just up my 1J timeframe.

No tools take it to a shop. Buy the crank bolt give the mechanic thats doing the work and have them deal with it. They break it they have to fix it lol.

yea what he said^^^^. those crank bolts are torque over 200lbs or was it 300 i dont remember but i looked up the spec one time. either way it was rediculas. need to remove your radiator grab a 600ftlbs impact 150psi and throw on that smaller socket like a sae instead of metric and pull that trigger
