A duct from near the top of the skirt of a two-piece piston carries lubricant to the skirt pin bore, on each side of the skirt, and lubricates the pin joint. The skirt is provided with a lubricant passage, such as from a shaker tray, to the pin bore on each side of the pin joint of the skirt, piston crown struts, and wrist pin on which a piston connecting rod is joined. Fluid sprayed against the crown descends onto the skirt and some passes through the above-mentioned lubricant ducts or passages for direct, continuous lubrication of the pin joint.
