Abstract
A push rod ball has an exteriorly oriented wear surface surrounding an interior core. The interior core is composed of a steel or steel alloy containing between about 0.1% and about 0.2% by weight carbon. A hardened case layer is of an essentially uniform depth is located between the exterior surface and the inner core. The push rod ball has a cylindrical throughbore transiting its diameter. A central through bore diametrically bisects the spherical metal body forming the push rod ball. The bore is bounded by a cylindrical inner wall composed of metal of the central core and the hardened case regions of the metal body. The push rod ball can be positioned on a suitable push rod shaft to provide a push rod assembly in which the weld region connecting shaft to ball extends through the hardened case region into the central core of the push rod ball.
