Also, we should not forget that the torque required to break a bolt loose may be only vaguely unrelated to the torque to which it was tightened. Corrosion, heat, and all that. ----- Original Message ----- From: E M To: [EMAIL PROTECTED] Cc: mercedes@okiebenz.com Sent: 8/19/2007 10:56:51 PM Subject: Re: [MBZ] Anti sieze on aluminum wheels
I've read about 85 f/lbs dry. When I had to put a 3 foot length of pipe on the wrench to get enough torque on it to remove them, I couldn't believe, even with an air gun, some idiot could get them on that tight! While cheaning the inside of the rim, once off, it gave me a chance to see just what a great piece of engineer that wheel is. It looks pretty plain on the outside, but a lot of thougth went into that wheel. I think they spent more money engineering the clip ring for the benz star in the centre, than most companies spend in R & D for the whole front corner suspension. :-) Ed 300E On 19/08/07, Robert Bigham <[EMAIL PROTECTED]> wrote: 250 ft lb is way too much torque on spherical collar screws holding on steel or alloy road wheels. My Daimler Benz Passenger Car Technical Data book says tighten them to 110 NM, equal roughly to 81 ft lb if I didn't botch the conversion. No wonder they are hard to get off when torqued to 250 ft lb. The wonder is that they survive being so overtightened without damage to screw, wheel, or hub.

I should know this by now!) All fixed now and it allowed me to give the inside of the wheel a good detailing too. Just have to do the other three now.
