Patent ID: 6874229

Claim:
A method for producing a connecting rod comprising the steps of: creating an initial form with a main shank, a piston end, and a crankshaft end; forming a small opening in the piston end perpendicular to a longitudinal axis of the initial form; forming through holes in the crankshaft end parallel to the longitudinal axis of the initial form; forming countersinks in the crankshaft end parallel to the longitudinal axis of the initial form; cutting the crankshaft end along a center axis perpendicular to the longitudinal axis of the initial form and form a cap and a first and second mating face; mating the cap with the crankshaft end; fastening the cap to the crankshaft end with nuts and bolts inserted into the through holes and countersinks; compressing the crankshaft end with a force sufficient to deform the crankshaft end; honing a circular opening in the compressed crankshaft end; and releasing the compression on the crankshaft end, allowing the crankshaft end to return to its original shape and form to an elliptical opening in the crankshaft end of the connecting rod.
