Zusammenfassung:	A method of manufacturing a connecting rod assembly including the steps of defining a small end of a connecting rod assembly having a terminal end and then defining a pin bore extending through the small end of the connecting rod assembly. A pair of channels is formed on opposite sides of the small end of the connecting rod assembly wherein the axis of each of the channels is substantially perpendicular to the axis of the pin bore. A bushing having a contact surface including at least partially annular grooves disposed thereon is installed into the pin bore of the small end. The connecting rod is then machined to reduce the width of the small end between each channel and the terminal end wherein at least a portion of the grooves are disposed along the distal ends to reduce the need to deburr the area adjacent to the pin bore.
