FYI- the majority of impact wrenchs/guns are rated at their tightening torque. take a gun that is rated at 300ft lbs. put it on setting 2 (about 100 foot lbs) and take it to your pulley bolt. whale on it for 5-10 seconds, then put the gun in reverse. MORE THAN LIKELY it wont come off
Also, the gun cant reach its potential if you dont have a big enough compressor. At the shop, theres no problems getting these bolts off... BUT if you only have a 5 gallon compressor, your not using the guns full potential, even if its a full 1" gun at 1,000 ft lbs. Not enough air for it....

Let's think about this...It's already fairly obvious that some people have this bolt on tighter than others - The question is, how much tighter? The impact wrench should be able to take the bolt out. I removed the slack out of the pully and tranny. The pully wasn't giving at all with the impact of the 550 ft/lb impact gun, so it is safe to say this bolt needed 550+ ft/lb of torque to remove it. I was breaking tools with around 400 ft/lbs. Even with the holder handle, I would still need to use the breaker bar and hand tools. I would say there is a good chance I would break something else even with the holder handle...
