摘要：
A method of shaping the gudgeon pin bores formed in gudgeon pin bosses of pistons comprises introducing into the bores portions of a shaped pin. A load is applied to the pin and the direction of the load and the shape of the pin are chosen so that areas of bore-defining walls of the bosses subjectto high stresses in use, and therefore liable to crack, are radially outwardly deformed to reduce the incidence of cracks.
