OK, this is my first timing belt job on my recently purchased 95 Accord (or any Accord). I am trying to remove the crank pulley bolt but this SUCKER IS REALLY STUCK. No previous car has ever defeated my 4-foot breaker bar before. This got me thinking... this sucker has NORMAL threads right? Counter-clockwise to REMOVE. I am hoping I am not actually tightening this damn thing. I've PB-Blasted this bolt repeatedly but it won't budge. Nothing in the shop manual about reverse threads either.

I decided to borrow a buddy's air wrench to see if I can break it loose. However, I have only ever used my compressor for bead blasting and am wondering what keeps this type of wrench from snapping the user's wrists off when removing a stubborn bolt. I hear these wrenches do a rapid "impact wrench" type of tapping that does the work. Is this true?

Is the air wrench the way to go at this point? What pressure should I run on my compressor? Thanks. -Mike

I THINK it is a reverse thread. Not 100%.

You have the right idea as far as removing the bolt and no bolt has never defeated my breaker bar with pipe also...until I did a axle change the other day. Snapped three 1/2 inch breaker bars to pieces. definitely try that impact wrench and start off on like 200 and see if that does the trick.

The crank pulley bolt is not a reverse thread, however they can be very stubborn.

I removed the one from my F22A6 with an impact @ 90psi (300lb). The same impact set to 500lb @ 90 psi didn't even budge My F22B2 crank pulley bolt. I required a 4' shed 40 pipe a breaker bar and 220lbs on it. That broke it loose!

An impact wrench works like a small hammer continuously banging at the socket. It will not twist your arm off if the bolt won't break loose. It will continue to hammer at the bolt until it breaks loose. Or it won't be able to remove the nut and it will continue to keep hammering until you give up and go back to the breaker bar method.

As for the operating pressure. The impact wrench should have a pressure rating on it. That is the PSI that you should set your compressor to.

Move the pipe lower and stand on it......watch out for the face plant when it breaks loose.

have broke my share of breaker bars on the same bolt, i bought a aircat 1/2" impact wrench with 1200ftlbs nut busting power and 1000ftlbs cont. power. since then no axle bolt or crank pulley bolt has stood a chance. it can be done the way you are doing it, might have to find a 300lb+ buddy to put mo *** in it, or if you know someone with a good impact(750+++ftlbs) that will prob be the easiest less sweat way to go.gl

Well there are a couple of problems here.
One; relocate the crank holding tool so that the breaker bar handle is against the ground, currently it is pressing against the suspension or body, which could cause damage.
Two; you need a taller and more stable jack stand, or you need to lower the car and remove that silly brick.
Three; rotate the breaker bar/pipe combo to a ~10 O'clock position.
Four; close hood, carefully stand on the end of the bar with your hands on the hood for balance. Jounce up and down on the breaker bar gently as if you were preparing to jump off a diving board. Prepare/Brace yourself for the bolt to break free or the breaker bar to snap. IOTW keep your knees bent, wear safety glasses incase the bar breaks.

Shouldn't the crank holding tool be on the other side ?
