ABSTRACT:
The design and construction of past piston assemblies having a wrist pin retained by a pair of snap rings positioned in a groove. Other past piston assemblies have a stubpin or cap positioned within a bore of a piston member or the wrist pin. In these applications the stubpin or cap is in continuous contact along the interface between the bore and the stubpin or cap. The present invention provides a device for retaining a wrist pin within a pair of bores of a piston member during operation of an engine. The device includes a shank portion having an outer portion thereon and only the outer portion of the shank portion being in contact with an inner surface of the wrist pin. The device and the wrist pin forming a wrist pin assembly. Thus, the device remains positioned within the inner surface and properly positioned the wrist pin assembly within the bores during operation of an engine within a bore of a cylinder liner. This configuration also increases the contact area between the wrist pin and the piston member increasing the life and dependability of the engine.
