The Jesus Bolt

[Rick G]

If memory serves me correctly this bolt is a right handed thread is it not.
I have already broken one 450mm Koken breaker bar and am now trying it with a 600mm Kinchrome bar and it wont move either way.  I know it is torqued to something like 160ft/lb but this is crazy. It cracked going anticlockwise but that's it, it's not going to move either way.
Any ideas besides eating more weeties for breakfast.

Yes Rick right hand thread. I didn't need to try to hard getting mine off as it hadn't been torqued correctly at the engine rebuild. So it had come loose stripping the woodruff key in the crank, I needed new crank boss, woodruff key, crank pulley and jesus bolt plus belts and tensioner's. I replaced the pulley and tensioners more as a precaution than need.

Tightening the jesus bolt you need to hold the boss I used a set of stilson's braced against the chassis, then torque the bolt up then using a degree gauge tighten a further 60 deg then another 60 deg then a final 30 deg.
I borrowed a friends 3/4 drive extension bar and still needed a 6 ft length of scaffold pipe.
So you may need to reverse the process to get it off, it's called the jesus bolt for a reason.

Good Luck

This is what I needed. Jesus was it tight

The locking device is probably not BMW speck but worked well

Thanks guys. Looks like a big feed of steak n chips is needed and I will see if the breaker bar is stronger than I am. I remember taking the one out of the M60 in the 7 series and how tight it was but just had that nagging doubt about it maybe being a leftie.
