How does one go about torquing the bolt to 258 ft lbs? There is a formula
on page 13.35 of the Bentley but I'm not quite sure how one would go about
using it. What is the adapter they refer to? I'm guilty of not properly
torquing the bolt after it came loose the first time I discovered it but I
didn't install it originally.
