Abstract
Metallic piston, wrist pin and connecting rod which normally do not fit together can be joined with one selected component being heated to effect the expansion thereof while another selected component is chilled to effect its contraction. With the heat differentials effecting relative size change the components can be loosely put together in a preassembly. The components in the loose preassembly are then returned to ambient temperature and to specification size whereby a central journal of the wrist pin is trapped between the piston pin bosses in one embodiment and the connecting rod is trapped by the shoulders of a reduced diameter pin journal in a second embodiment to form permanent piston, connecting rod and wrist pin assemblies.
