Are you trying to take out the crank pulley? You don't need the crank pulley holder. Here how you do it:

-Jack up your driver side, take off the front driver wheel.
-Lower the jack so the car is level as if the wheel was on.
-Use a long 1/2" extension, long enough so it will come out side the fender.
-Put a jack stand near the end of the extension so it keeps the extension straight and level.
-Hook your 1/2" breaker bar to the extension.
-Put the end of your breaker bar into a long 6' or whatever length steel pipe. The longer the easier for you. (get it from Home Depot or Lowe)
-Put your car in 5th gear and have someone step on the brake hard while you outside pull on the steel pipe.

I guarantee the bolt will come off in the first try. I've done this so many times already. No need for the holder tool and air compressor. Even with my 400 lbs impact, I could not open it.
