Jesus Bolt?

[Zoz740i]

So I have been waiting for my crank holder tool to come in the mail ordered on Friday shipped today I have been bitting at the bit to get at that bolt seeing the degree of difficulty of the task at hand was (or so I read) it my be just me or are nights more restless with a half done job calling from the dark. So I got creative on Saturday morning woke up with one thing on my mind "ima get that bolt off today!"
So I read thru forum postp for about an hour.Can't lie at first I realized I should wait for the tool and let the rationale members with experience prevail................ But then I got a second wind of courage.....I got to Jerry's project post and really tried to stop myself but couldn't is the tool needed is it not so I keep read one success story 2 success stories confidence boost. So I concluded maybe to torque but not to loosen just gotta keep the crank from spinning. If your still reading this is indeed my very first guide job I'm not a mechanic but with the help of you guys I am able to do this so you will always have my gratitude to the moderators keep up the Great work.Without much a do I give you my make shift crank holder tool.Attachment 634973

Had no extension pipe just the breaker bar had the crank tool positioned on top of lower pan resting on A.C bracket pulled hard and steady worked like a Charm. Woooo Hoooo!!!
Hope this helps someone down the line (photo is a bit dark)

Yeah there’s a lot of hand wringing about this Jesus bolt- from me included at the time- but once you get it held it’s no big deal. Glad you got it.

Make sure to get an extension pipe for your breaker bar when it's time to reinstall everything back!

K I did consider getting one i don't think the flex i put on the breaker bar taking it off could withstand the torque needed to tighten it up Thanks

When I had to remove mine to change my water pump, I was ready for a fight. But I just used vice grips on the flywheel with a block of wood as a stop, and thought let me just give it a shot with my ratchet. I will say it was tight, but it just came off. No breaker bar or extension. When I put it back on I just put it on as tight as I could. I've done it twice now. I do believe someone had been in there before me as the water pump did have one bolt missing, but strange that I was putting in another one at around 70k.

I thought of vise grips first it couldn't figure out how to hold it in place. Why did you have to remove this bolt to do the water pump? I did my water pump about a month before my guides failed had little to no trouble getting it out and in.

I went under the car and clamped them on the tranny fly wheel. The block of wood wedged into the bell housing and the fly wheel teeth as it started to turn. You have a V8. I have a V12. One stupid bolt is hiding behind the balancer.

When putting it back, do you guys go with just some high torque like 750Nm or follow the BMW spec 100NM + 120 degree if I recall correctly.
I could never make it to 120, around 90-100 was max with long breaker bar.

Not a bad question. A while back I did see a German video of the the guides being done and the tech used a special tool that fit behind the crank holder tool to torque to specs just curious has anyone else seen or used this tool?

See the thread about my car, post #21. I got mine to somewhere between 130 and 140. I didn't go to 150 since I reused the bolt.

Also, I just printed a 180 degree protractor off internet and taped it to my crank holding tool. It was nice since I could mark the desired degrees of torque. No need for fancy tools!

I thought reusing the bolt is a no go as it is a stretch type bolt. Template with degrees great idea!!

I used the same bolt twice now. And only as tight as I could get it with my ratchet wrench. No torque or degree measuring. It's been over 100k since the first time.

Food for thought......hmmmm
