I can probably get the bolt out.

Recently I removed a domestic-threaded crank bolt
that someone had impacted into a Honda, resulting in a
beat up crank pulley that wobbled, a damaged keyway in the crank,
a damaged keyway in the crank pulley, etc. etc,.......
I sure wish that guy had me do the work to start with.
It would have saved him some money to get it done right.

I also do on-site impact wrenching for crank pulleys and
many other things. PM me if you want someone to look at it.

What part of town are you in?-Bob
