Anyone know what to torque the crank bolt on an 86 951 to?

155 ft/lb?

Yep. 155ft lb which is 210Nm.

Thanks to all! Trying to get this thing back on the road!

155 ft-lbs or tight as you can get it. Who has a 155 ft-lb torque wrench anyway?

And make sure you dont catch the edge of the power steering pulley. I think we have all done that! It ends up bending the pulley and screwing up your oil pressure.

I do. . . and I just used it to put the crank bolt on today. It takes my fat dad pushing as hard as he can, and me pulling as hard as I can while holding the socket square, and exactly 3 bad words.

a 15/16 socket isn't that great on there. get the 24mm socket and make sure its on square. I was dumb and rounded the first 1/8th of the bolt off with a 15/16. . . and I had that washer on backwards

A 155 ft-lb torque wrench is easy to find (mine goes to 250) but getting that sucker OFF is a PITA sometimes! I estimate that to get the one off my n/a car last time I did the belts I was pulling on a 4' breaker bar with about 75 pounds of force - that's 300+ ft-lb!!!

Those things can be a PAIN to get off to say the least. Get a nice pice of pipe unless you've already BTDT and are in reassembly mode. If so, use some anti-sieze. It'll make life easier next go-around.

15/16 = .937"
24mm = .944"
The 15/16 is a tighter fit, though I admit something about that 24mm figure just seems ...special.

It was probably the fact that I had the washer/spacer on bass-ackwards that gave me problems w/ the 15/16. but the 24mm did go on there easy and stayed square. worth the 4 bucks IMO.

I am in reassembly mode now. Your right, getting things apart is a huge PITA! 2 ft breaker bar and a 3 ft piece of pipe, when it finally let go it sounded like a 30 30 going off at the range. I have a 275lb torque wrench and it always seems like 155 lbs is not as hard to get to as it is to take apart. go figure? Thanks again to the collective rennlist wisdom!

"getting things apart is a huge PITA!"

I'm not trying to make fun of anywone here, as I've been thru the PITA part removal processes in the past myself. It just kinda makes me chuckle when I hear these kinda things. First thing I think of is, I'll bet he's trying to remove that bolt thats been on that car for ages with a 1/2" drive breaker bar. I would imagine that must be kinda like going to a gun fight armed with a knife. Ya probably will not fair well..........your gonna get killed.
The right tool for the right job, and everything goes much smoother and easier. Of course the break off torque is gonna be higher. Typical. Thats why a 3/4 drive socket/breaker kit comes in so handy. Thats why a good 1/2" drive impact wrench comes in so handy. Thats why all service shops have these tools. They don't want to kill themselfs or damage the car doing it either. If you don't have the proper tools, yep, a lot of these jobs WILL be a PITA. I know a lot of you just don't have the ability to get these tools. I just find it kinda funny when people say how hard some of these things are, knowing that most of the problem is the lack of using the right tool for the right job. Just my observation, didn't want to start any heated discussion over it.

You are exactly right. I guess thats why my tool chest has a weird collection of "the right tools for the job" I seem to collect them with each job I do. Since I am rapidly becoming an old man I find that using "the right tool" instead of brawn saves me and the car a lot of problems. especially the next day!
