Wheel Torque Specs

Howdy :)

Anyone know the correct torque specs for the AMG 3-piece wheels, or for any W126 wheel for that matter - do they vary from wheel to wheel?

I thought I knew from the little info I gathered in a past wheel thread and since it came from a member who generally know's what he's talking about, I accepted it without question.

But when I started a thread called "Q about Torque Wrench", inquiring as to what size wrench would be best to use, the topic of torque specs came up and it appears that everyone in that thread has mixed opinions on what is the correct setting, which seems to have led to a just little confusion.

If anyone can straighten the matter out, I think it would benefit us all.


Cheers :cool:

+1 for 80-85ft-lbs for my alloys. My Mitchell manual blatantly states what equates to 80/82ft-lbs.

I'm not an engineer (yet...) but IMO the 10ft-lb spread won't be noticed by the bolt/hub to any degree that it will compromise eithers tensile strength. Of course, you don't want to put 60lbs of torque on the bolts, or go nuts with 195lbs, but within the 10-15ft-lb range, I'd reckon the only one who'd notice (as has been mentioned in the torque wrench thread by 500MPL) is you if you have to remove the wheel with the little tire iron in the tool kit.

As is procedure by some fleet mechanics, if you put anti-sieze on the bolt, reduce torque by 5ft-lbs due to the added lubricity giving the wrench lower reading than actual. Just in case we want to get even more technical.:)
