17mm Crank bolt revmoval; It keeps spinning

I cannot get the center bolt out of my crank sprocket. I had no trouble removing the 5 little ones around it, but that was only because I could put a 17mm open-end on the center one to keep it from spinning. Now that everything is off and I just have the one big bolt left, I can't find a way to stop it from spinning to even begin to get it off. I've looked for posts to help, but they don't really have an answer to keep it from spinning.

Welcome another Minnesotian! :thumb

Put it in 5th gear, have someone step on the brake, and use a breaker bar. Should work fine. Do the same, when torquing, upon install.

another trick, remove the oil pan and stick a piece of wood between the crank and block to stop it from spinning. (use at your own risk)

There is a hole under the car in the trans bellhousing for the purpose of inserting a punch, hard screwdriver or other object for someone to hold the flywheel while you remove the crank pulley bolt. Note that bolt is pretty tight and you should use a extended handle breaker bar with a six point socket to remove it.

I use heat. Like a BurnzOmatic with Mapp gas. It has loctite on it from the factory. Make sure to use just a bit when you go back with it and the 5, 10mm ones. Welcome to the forum

The 5th gear and brake locked it up really good. I have a thirty-two-inch breaker bar along with some WD-40. I've been trying for a few hours with no movement. It's funny how they just breeze-over this part in all the tutorials. I've heard people say it's the hardest bolt to take out in the whole car! I'm not sure what to do now.

My objective is to replace the crank seal. I've even tried my impact wrench to get it out with no luck.

here's a "how to" thanks to Bad Bent. might as well do both seals while you are in there--and replace the timing belt too
I hahttp://geometroforum.com/topic/3083546/1/ve: Crank Seal How To and How to Cam Seal. that you can start with.

I've looked over those tutorials. I unfortunately got stuck on the crank sprocket bolt. I've got all the parts. I was planning on replacing the cam seal, crank seal and PCV valve. My timing belt is new so I don't need to replace that.

It does work to put a 17mm socket with a breaker bar or rachet pinned against the ground or frame and turn the engine over with coil disconnected. It will break free easily, but you must have it set up right or the bar could damage something. A variation (even more dangerous) is to lift the wrench with a hydraulic floor jack. If the car lifts put someone fat in the front seat.
