This patent describes a friction reducing engine rocker arm construction. It comprises: a rocker arm having a longitudinally extending body, the body having an opening therein at least partially circular in shape and defined by an annular wall portion of the body, a fulcrum having a mating portion at least partially circular in shape. The fulcrum being rotatably mounted in the opening with a slight radial clearance space between the wall and fulcrum, cam means having a no-load base circle portion and a load contoured portion. The cam means being engageable with the body to pivot the same about the fulcrum. The cam means is under no-load condition when contact between the cam means and body is made on the base circle portion of the cam means, the cam means loads the body into contact with and against one side of the fulcrum, and lubricant inlet means to supply lubricant under pressure to the clearance space at a pressure level greater than the no-load force of the body against the fulcrum.
