Anyone have any suggestions on breaking this baby loose? I've tried an impact, break over bar etc.....and it won't budge!!! :bash: Are the threads right or left handed on the LS1? I've even tried hitting the wrench with a hammer with no luck. The engine is out of the truck and I know the motor will try to turn over but that shouldn't stop me. Has anyone else had this problem before?
Thanks, Lance
Might not be the smartest way but both times I have taken mine off I just jammed a breaker bar through the balancer up against the block and wedged it in. Then broke the bolt loose. :thumb:
It's a right handed thread. It should be tough as hell to remove. You'll need a breaker bar to loosen it. Put an old flywheel on the transmission end and hook a chain through the holes and then to the exhaust manifold. After than you can crank away at the bolt counter clockwise from the front of the engine. There is thread locker in the bolt so it's going to be tough to break loose.
Cool! Thanks for you guys input! I didn't know about the thread locker. I'll give her another try tonight. I just didn't want to break anything.
Got the bastard! That had to be one of the tightest bolts I've broke yet on a motor!
That bolt is a mother to tighten to spec, also. Get you a cheater bar! :laugh:
I had to stand on a 4 ft one! :eek: LMAO
This is my bolt remover.... lol..... and a 120PSI+ Glad you got it out without breakage. I know it's a PITA when one snaps on ya.

Nice impact! That's what I buy my guys at work. I thoughbt I was gonna have to borrow one of our 2" drive impacts but I'd need a little help to hold it LMAO :eek:
O.K...Now that we know how to remove it...What is the proper way to install a new one? Torque spec, tool, etc...Thanks, Gar
Is it just a straight 200 foot pounds & your done? :duh: GarQuote:

Re-install using the old bolt and torque to 240 ft lbs. Remove old bolt and torque new bolt to 37 ft lbs. Now tighten the bolt an additional 140 degrees. You're done.
I would replace the bolt. I bought one from GM for $3.29 plus tax. That's cheap and you don't have to worry about rounded off threads next time. :cool:
Thanks for the info guys! :wave: Gar
U can borrow or buy a tool to remove it at Autozone then take an impact wrench to it. It willl come off. Use a fine machine oil if necessary. I am guilty of it in the past but I would never ever again use a hammer, crow bar or whatever. You have endangered your balancer if you do and there are main bearings and other inportant stuff back there. More stuff in the LT1 and above engines. You can also cool the crank as well. But I've never had one not come off with a decent impact wrench. Sometimes your balancer will break but that's ok. They are cheaper to replace than some other things. /off soap box
