A fixed traction pin (23) is inserted into an eye (4) and has a thrust surface (24) that mates with an annular surface of a leg portion (6). A traction pin (28) is inserted into the eye and has a thrust surface (29) that mates with the annular surface of a cap (7) and has a larger radius of curvature than the thrust surface (24). An actuating unit parts the traction pins to break the cap from the leg portion. Independent claims are also included for the following: (a) a method of machining steel connecting rods; and (b) a low case hardened steel connecting rod.
