re torueing crankshaft bolt

[zep06]

so got it off and everything changed... now how the hell do you get that thing back to where it was

Yea, like 300 and something ft lbs. I took mine to a shop to have it torqued considering my torque wrench only goes to 150. The shop was right down the road so driving it there without the coolant system intact was not a problem for me. Worst case, if you have a compressor, hit it with an impact and hope for the best. Thats what I was going to do but someone stole my impact from my mothers garage.

Curious, why did you both pull it to begin with?

I didnt, the PO did, I bought the car like that. The head was removed, so I am assuming he thought it needed to be pulled out to put on the new timing belt.

You have to pull it to change the two lower seals.

I doubt that the guy did that. It looked like he pulled it all apart and got scared he couldnt put it back together so he decided to sell it. Works for me, got it for $400, and it looks pretty good, and now runs great. A little hard to start when cold but runs like a raped date when all warmed up!

I think you are supposed to replace the crankshaft bolt with a new one. I know you are on the e36 motors.

If you put the car in gear, pull the handbrake, and have someone standing on the brakes in the car, you should be able to get a torque wrench on the crankbolt to torque it without the motor just turning.
That's if the car has a manual tranny. If it's an auto, you'll have to build a tool to hold the crank while you tighten it.

I read both my books (Chilton/haynes) and neither of them said to replace it. Can anybody with a Bentley confirm?

to change the timing belt?

[vr2jetta]

to change the timing belt?

Is it necessary to pull the crank pulley to change the timing belt? The pulley was all ready pulled when I got the car so I wouldnt know, and God knows how much you can trust the "quality" books I have.

[whodwho]

It isn't necessary to remove the large crank bolt, you remove the six ones that hold the front pulley/dampener you can slip the belt out and in around the lower sprocket still installed. Yes you would need to remove it if you were to replace the front seal which rarely needs to be replaced.

No, you do not have to replace that nut. You can use loctite on it if you want though, I would recommend it.

The torque is 300 (about) ftlbs. However, that nut doesn't do much but hold the harmonic balancer on the car. The high torque probably has to do with the standard torque for a bolt/nut of that size and the fact that it spins and catches a lot of vibration (it is hooked to the crank shaft). Use loctite, put a 1/2 in breaker bar on it, put on a 3ft cheater bar and pull as hard as you can. You'll get it tight enough

you dont think the loctite will make an already pain in the ass even more so to take off in the future? ive heard some horror stories of people trying to get that bolt off only to find it was loctite..

[Hallen]

Of course it will make it harder to get off. However, probably not enough to notice when you are yanking with a 1/2in breaker bar and a 3 foot extension. If you can torque to the spec (you have the right torque wrench) then don't worry about the lock tight. If you can't, use a bit of loctite. The loctite is there to keep the nut from backing off due to vibration. It really shouldn't cause too much of a problem when taking the nut back off.
