Quote:I worked for a couple years in a refinery with all sorts of fancy machinery, pumps, and compressors. We were told exactly the opposite - use copper-based anti-seize on every screw and bolt on which we did not use LocTite. They said that torque settings on dry bolts would not be accurate.

They said that a bolt or nut does not move until you apply a fixed threshold of extra torque. That is,if a nut is already at 90 FtLb, it will not move when you apply 91 FtLb. It will only move with, say, 97 FtLb.

We were told that the torque threshold to get dry nuts & bolts moving was much higher than when antisieze was used. Therefore, going from 90 to 95 FtLb was difficult. The nut might not move until 105.


Anyway, that's what I was told -- in a very loud voice by a big guy with a wrench in his hand.

Quote:Funny,

I was garaged near a guy at T-bolt last October who had centerlocks his Porsche.

He asked for my help putting his wheels on. Not sure how much of this was drama for my benefit, but it was some absurd multi-step process putting those on. In the end, he had this humongous torque wrench with an extended breaker bar on it that was necessary to get the torque up high enough to the factory setting.

Maybe Porsche has made a secret pact with folks like Doughtery's to make it almost mandatory to hire track-side service.
