Torque values

Stopped by the hangar and confirmed 1 1/16".

Just a note on torques. The I've found the torque for the lug nuts to be 140#'. Keep in mind this is a DRY torque. That means the threads of the studs and the lug nuts need to be perfectly clean and 100% dry, no oil or anything on them. It is easier to lube the threads and use a wet torque value than to try to clean and dry the threads. I always lube the threads and torque to 110#' The following is from the Popular Mechanics web site.

"Most times, the specified torque value assumes clean and dry parts. Clean means no dirt, rust, dried-up *gasket sealer or anything except shiny metal. Wire-brushing the threads will help remove rust or sealant. Engine fasteners, like head bolts or main cap bolts, are often specified to be torqued with 30-weight engine oil wetting the threads and washer. If you're installing a fastener that has a dry torque spec, and the threads and bolt face are oiled, you'll need to reduce the torque by 15 to 25 percent, because the slipperier surfaces will decrease friction. Teflon-bearing lubes or moly-sulfide engine assembly lubes can reduce friction enough to require a 50 percent reduction in tightening torque. Even casually substituting a zinc- or cad-plated bolt or washer for an unplated one calls for, respectively, a 15 or 25 percent reduction in applied torque, because the plating acts as a lubricant. Fail to heed this advice and the fastener will be seriously overtightened. You'll either snap it or crush a gasket to the point where it leaks."
