Pulling a Crank Shaft pulley

[ForcedFirebird]

Well, I haven't!

I am getting tired of people acting like I am fucking clueless around here.

Not trying to make you sound clueless, but in reality you are telling people that an impact is fine for 350 ft lb. If they take your advice and it's not tight enough, they will ruin their motor if it comes loose. Is it really that hard to do it properly?

An impact gun set to 150psi and hammered on repeatedly will get the bolt loose. if it is held on by 350psi; how is it, 120 psi (which I used) could remove it?

Probably removed once before

The air pressure used to drive the impact wrench has little to do with the torque made by the wrench. The torque produced is mostly a function of the internal design of the wrench.

Probably removed once before

And not torqued correctly on reinstall ...

that isn't true...I have never removed the one I had because the motor was a rats nest 320k kilometers all original. neither case is true in mine.

But what was written above re: the internals of the gun makes perfect sense to me. but I would think the air pressure would have something to do with how much the gun can take and give.

The air pressure suppled to the gun does have an affect on the torque generated, but that is more a factor of the the rate of impacts.

OP,
To get mine off, I removed the grill kidneys, radiator & AC condenser, attached the Pelican parts pulley holding tool and set it so the end of said tool was torquing against the floor. Then I used a 3/4" impact gun. I had tried the aforementioned posts here, (huge cheater bar on a snappy 3/4 breaker bar) and thought I was either going to break the tool or break some part of me if the bolt gave free.

And +1 on torquing it back tight with a proper torque wrench though I did put some anti seize on the bolt treads before torquing.
