Torque specifications are typically for dry parts (not lubed). There should be significantly less torque used when lubrication is inlcluded, as much as 40% of dry torque spec. Specifications take into acount the assembly and the fact the part are dry. Why would you lube the parts? Are you preventing rust or other corrosion concerns? There is a possibilty of over torquing if you use lube unless you know the proper torque spec to use for the lubricant used.
