how do the spec-s of an air impact wrench relate to the air
compressor?
i need to loosen a crankshaft pulley bolt that is torqued at 134 ft-
lb. on a 1998 honda civic LX. i have a sears craftsman 1.5hp 4-
gallon @90psi air compressor. i don't yet
have an air impact wrench. what should i look for in terms of psi
when i go to buy one, such that i can use that air compressor to drive
the impact wrench to loosen the bolt? tia.


Forget about that. Just use a breaker bar long enough to be braced
against the ground, disconnect the ignition, and hit the starter for one
second.

Got that tip from my mechanic after spending three days trying to help a
friend loosen that pesky nut, and it worked as advertised.
