Torque Spec

Greetings fellows,
Does anyone know the torque spec for the lug bolts on the rear wheel on the 11S?

Thanks, Michael

Not to bust your balls, but did you even try to search for this? I did and found this:

No, I was hoping that someone on this list would know this.
However, I did look at that site and they say 50 newton meters. Great!. My torque wrich uses foot pounds [or pounds feet].

Well, Bikerfish put a converter into his tables...

Tightening torques
These have been converted from Nm (Newton meters) to
the nearest 0.5 ft.lb. (foot pounds) by dividing Nm by 1.355.

It is 105 NM
converted to 77.5 ft-lbs

It is NOT 50 N.M ! 50 N.M is only for preload.

I have never used a Torque Wrench on mine. I use my Calibrated right Foot!

I push down hard with my right foot against the Tool Kit Lug-Wrench while just beforehand reaching over to push down on the Brake Pedal with my right hand.

105 Nm = 77.44391 lbf-ft
50 Nm = 36.87805 lbf-ft

In over 50K miles I've never had a loose wheel or a broken Lugnut.

I break the Lugnuts loose in similar fashion.

I am paranoid on these single-sided shaft-drive swimgarms so I do not use the German spec (guten-tite!) and instead slavishly follow a star pattern hand tight, then 50% torque values, then 100%.

FWIW...

Thanks guys for all your help, I didn't mean to cause such a stir. hehe
I printed out the page with all the torque specs that bikerfish1100 referred to. I gave a copy of it to my roommate and he did the job.

Thanks again. Had I looked it up, you guys woudn't have anything to talk about. hehehehe
Seems to me I did copy that document before. It's probably in my file cabinet with all the other BMW stuff.
Cheers

My method is the same as R111S, "the old foot on the spanner trick" I didnt realize that the torque was so high. I might go and wave my torque wrench at them to see how close I am to the right tension.

Thanx
Dave

as was already noted, 50, then 100, which comes to about 78 ft/lbs, which is the same as the wheel bolts on an e30...

Question, how does one follow a star pattern with only 4 bolts?

I'm a little surprised that a long time member and engineer (known for his precision ways and precise record keeping) would suggest just hand tightening, or more correctly applying just one "right-foot-pound" to the lug nuts when a question is posed by a member.

We have had documented cases here on the board before of the wheel working it's way loose. So why not do it right? Especially since everyone has different strength levels in their arms, legs, and back and will end up with different nut stretch, and I'm not talking hernia...

Here's a thread...

loose rear wheel bolts at 60mph

Hey, I was not offended by any of the comments. Bikerfish is right. I have been acound this list long enough to search these things out. I must have been having a senior moment. I looked at my computer and thought someone on this list must have this info on tip of their tounge just waiting to tell someone. hehehe.
Thanks anyway guys. At least I woke a few of you up. hehehe
