underdrive pully un-install

Can anyone tell me how to take off my underdrive pully bolt with the block out of the car with no flywheel/ flexplate?

You will need a gun that can generate enough torque to do it. I had to go buy a new gun the last time I took mine off because the one that came with the compressor couldnt cut it.

As long as the compressor can generate the needed pressure to run the gun, yes. My air tools use ~90 psi fwiw.

Mine say 90psi, but I run them at about 150psi. If you're having trouble, you could put the wrench/socket on the bolt and whack it with a hammer. One good bump will usually loosen anything.

I used an Ingersoll Rand impact at a guys shop that was so powerfull, that it actually rotated the world instead of the bolt. I swear it had to have been running on 4000psi nitrogen or something......
