crank bolt help needed

[noredline]

I have searched and read every thread that was posted about the crank bolt and the bitch that it can be. I decided to thread some rope down the #1 plug hole to prevent the pulley from turning, however I can not get enough force to break that bolt loose, and I am a big guy. It was put on with air tools so I am curious if I just need alot more power. I am also using a 18 inch breaker bar, do I need a larger one? Also had tried bumping it with the starter before with no luck. Any help is appreciated.

I think its torqued at something like 195ft/lbs. I had someone in the car holding the brakes with the car in gear and one hell of a breaker bar. You should be able to get it loose with a good impact wrench.

I've never had the starter bump fail me. If that's not working for you, you're pretty much FUBAR, the starter puts out WAY more torque than an impact gun.

I used a cheapie craftsman impact gun that came with my compressor, and it did the job. I was surprised.

craftsman guns are not the way. If you know someone with a torch get the bolt hot and it will spin right off.

That what I did, one quick turn of the key (cps disconnected) and it broke loose. I was surprised how easy it worked.

Geeze. Use hte breaker bar, and use the handle of hte floor jack. I think a 10 year old kid could do it with that much leverage on the bolt. I've never had a problem doing it this way.

put a breaker bar on it and use a hammer.

yep, thats teh onyl way you can do it w/ the engien out of the car. w/ the head off.

yup....18" breaker bar and the handle of your floor jack (or any large pipe that will fit over the breaker bar) 5' of leverage does the trick pretty easy

I couldn't get a 550 ft/lb impact gun to take it off, even when it was torched!

I ended up having to wrap a chain around the engine stand, bolt it to 3-4 flywheel bolts (snapped about 2 trying this), put a large block of wood standing up under the crank shaft (i was putting so much torque on it, it wanted to bend down alot and i thought i was gonna bend or break the engine stand). I also ratchet-strapped it to a cherry picker for extra support, it was a huge bitch to take off!

Go to Home Depot and buy a 4 foot long iron gas pipe to go over the handle of your breaker bar.

You guys need a bigger impact, My 1 inch drive on 175 psi has never found a bolt it can't break.
