In machines for reshaping cylindrical metal bodies, wherein the machines include pairs of opposite, axially aligned ram assemblies, cams are provided for axially positioning tooling rams slidably supported by ram housings. The cams are provided having axially opposite cam guide surfaces, and cam followers are mounted on one axial end of each tooling ram with a cam follower being pivotally mounted to the tooling ram and biased into contact with a cam guide surface.
