Bob, The torque values for the diaphragm cover are *VERY* small! They are listed in inch-pounds, not foot pounds. I don't recall the actuals, but it is not even hard hand-tight. Too much torque will cause the cover to act like a cookie cutter on the rubber diaphragm. Use the supplied loctite to keep it from coming apart.
