Default Crank pulley bolt

Any advice on getting this thing off? I rented the tool to secure the pulley and tried using a breaker bar and an electric impact but neither would crack it loose. I'm afraid if I try to man handle it too much with the breaker bar I'm going to break the bolt off in the crankshaft. Any help would be appreciated thanks

How bad is it rusted? Mine came off with a 18v electric impact. Anything less wont make it move. Usually an air impact will spin it right off.

You run a higher risk breaking the bolt head by hand than by impact.

Don't be a pussy, if an impact cant get the job done make the biggest breaker bar setup you can with a cheeter bar attached then jump on it as hard as you can. Works every time ;)

Don't be worried about breaking the bolt, you'll bust sockets and breaker bars before that bolt breaks.

X2 on the air impact gun, spray some pb blaster and maybe wd40 so it pens the "rust" .

I did use a cheater and tried standing on it lol. The bolt pretty thick so i think it'd take a lot to break it. It's like someone but that bitch on there with some red lock tight! I'll try some pb blaster or somethin, I keep hearing my dads buddies talking about some spray they call "panther piss"??? Haha but I'll keep trying with the breaker bar! Thanks guys

Yup. Have done too many of these to remember. Broken quite a few breaker bars doing them, have never broken a bolt. The tensile strength of that bolt is over 210k PSI. Not going to break the bolt. I have maimed both a snap-on and a matco breaker bar on crank pulley/axle nuts. And many other lesser bars as well.

Surely you're joking, leverage is physics and the workable area of force (bolt head) compared to the leverage (breaker bar) is way to little to break a breaker bar before the bolt.

Either that or I've never experienced a bolt THAT bad. And my car sat in a field for 6 years lol

Nope. Not kidding. The workable area of the bolt head may be smaller than the leverage of the bar, but the 1/2" stub of the bar is weaker than the bolt. Like I said, I have also broken them on axle nuts. I have worked on more of these piles than I care to remember, and every time I do, I tell myself, not without air this time. That is never the case. So sometimes stuff breaks. And it is very rarely the bolt.

Glad to hear I'm not the only one to have busted a snap-on breaker bar when doing this. I've gone through a good 8+ craftsman's doing axle nuts.

All Snap-On or Matco does is exchange out the broken head. Knock the pin out and put a new head in, press the pin back in. No issue there. Lifetime warranty.

Just as long as you dont tell them you used anything like a pipe for more leverage.
Other than that, there should t be an issue exchanging for another one
