How many ft lbs of torque should I be looking for in a impact gun.....my 250lb isnt cutting it thanks

 

I have one that has 1200lb. It has no conscince.

 

-any IR gun should be good enough.. the minimum they make is like 500ft lbs ( i think),
-sears sells IR guns under craftsmans name...also make sure you have a good compressor pushing the gun, most of the time its not the gun being culprit for not being able to loosen a bolt; its the psi from the compressor....
-if all else fails hit up a snap-on truck and get a hex tool and a big breaker bar..

 

any high quality Impact Gun (made in USA) rated at 250 ft/lbs or more should do it..

 

I've seen a couple of those bolts that I'm sure took more than 500lb-ft of torque to break...such that I was worried about the crankshaft holding up. They all seem different though. Some are easier than others. Good luck.

 

My IR IMM240 gets most crank pulley bolts. For the really stubborn ones, my Matco 3/4" impact gun will not be denied

 

sometimes they are just really hard too get off.. i did an accord timing belt the other week and my 235ti wouldnt even phase that dumb bolt.. the hex tool and a long *** breaker bar did the trick tho
