a. Tightening Specifications
Use a reliable torque wrench to tighten the parts listed, to insure proper tightness without straining or dis-
torting parts. These specifications are for clean and lightly lubricated threads only; dry or dirty threads
produce increased friction which prevents accurate measurement of tightness.
