I've searched the forum regarding removal of the crank pulley bolt, and some folks spin 'em right off with an air impact wrench (even an electric one) and others claim that no way the impact works unless ungodly torque is available. I'm looking at the Haynesmanual for my 2000 civic and notice the torque spec for pre-97 is given as 130 Ft-lb, and 1997 and later is given as 14 Ft-lbs followed by an additional 90 degree turn. I don't have a clue what final torque that additional 90 degree turn yields, but I'm wondering if this difference in torque methods is the reason some come off easier than others. Anybody care to offer their thoughts or experiences with this?

 

its actually called the arc torque method. we use it in the army workin on gas/turbine engines alot. its extrealmy acurate if you do it just like it says. other than how old the car is having to do with some of why it comes off harder than other, its luck weather it comes off easy or not. just think how many revolutions that pulley has made during the life of the motor. each turn tightening it. anyways, either way you cant go wrong if you just follow what the manuel says for your car. trust me, the 90 degree turn one, is just as accurate as just tightening it to 130
