Abstract: A piston-connecting rod assembly for an internal combustion engine includes a piston pivotally mated to a connecting rod by a piston pin. The piston pin includes a first pin end, a second pin end, and a midsection. When assembled, the first pin end and second pin end are respectively received in a first pin bore and second pin on the piston while the midsection is accommodated in a cross-bore through the connecting rod. The piston pin may include a wear resistant layer applied over at least a portion of its external surface that may include at least one of tungsten disulfide and molybdenum disulfide. The wear resistant layer may be applied as part of a manufacturing process performed on the piston pin.
