....I've not heard anyone say it's failed to remove a bolt.
I may be the first, ever.
No dice using an Aircat impact gun and a Lisle socket on our then "new to us" 2012 Accord EX-L. I ended up damaging the Lisle socket's square drive, and elected to stop before I more thoroughly rounded the corners.
I had the Aircat running at maximum sustained air pressure allowed by the manual. 1,295 ft-lbs. of torque available, per its specs. Did f@#$ing Godzilla put this crank pulley bolt on at the factory?!
Had to resort to 1-inch square drive tools (like for using on tractors) and a 10-foot stockade post as a cheater bar. Easily over 1,500 ft-lbs. of torque required to break loose that fershlugginer crank pulley bolt.
I thought I was going to break something on the engine, and when the bolt banged loose, I thought, "Well, now you've done it..."
Luckily, I loosened it that time without causing further damage to anything else.
If that did not work, I was going to surrender and take it to a nearby diesel rig shop.
