ABSTRACT:
A piston and connecting rod assembly comprises a one-piece yoke thrust bearing disposed between the piston and connecting rod to provide bearing surfaces therebetween. The piston includes a pair of wrist pin bosses disposed therein and in spaced-apart facing relationship. The bosses have oppositely disposed faces with axially aligned bores therein, and the faces have disposed therein respective shoulder-like depressions. The yoke thrust bearing comprises a pair of washer portions in abutment against respective boss faces and interconnected by a yoke element, and the washer portions have respective projections conformably received in respective depressions, thereby aligning the holes in the washers with the bores and preventing rotation of the yoke thrust bearing in the piston. On end of the connecting rod is received between the washer portions, and a wrist pin is passed through the boss bores, washer portions, and the connecting rod opening to thereby pivotally connect the piston and connecting rod together. A method of assembling the piston, connecting rod, wrist pin, and yoke thrust bearing is provided.
