Abstract
A wrist pin and wrist pin retainer are combined in a subassembly which prevents inadvertent removal of the retainer from the assembly. The subassembly is placed in a bore defined by a piston and a connecting rod with at least one annular groove formed in the bore. When the subassembly is located in the bore, the retainer coacts with the annular groove to secure the wrist pin in the bore.
