Abstract
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. At least partially annular grooves are formed within the pin bore adjacent the distal end of the pin bore. The connecting rod assembly is then machined to reduce the width of the small end between each channel and the terminal end to provide a small end having a reduced width configuration wherein the grooves are disposed along at least a portion of the distal end to reduce the need to deburr the area adjacent the pin bore.
