Floating piston pin retainer

The assembly comprises a piston defining a transverse wrist pin bore, and a pair of grooves extending axially in the piston alongside the bore from an outer end to an interrupted portion spaced inward from the end. There is a connecting rod having a pin end receivable in the piston inwardly adjacent the interrupted portion and a pin opening connecting with and forming an extension of the bore. There is a retaining clip comprising a body including a pair of axially extending spaced parallel stringers having base and head ends and connected intermediate the ends by a bridge. The stringers have at their head ends outwardly projecting hooks having backward angled end ramps. The stringers have at their base ends radial arms engageable with the piston adjacent the bore outer end. There are a pair of fingers one extending from each radial arm spaced from and parallel to one another and the adjacent stringers, each finger having an inner end with an outwardly projecting hook having a backward angled end ramp. The clip is received in the piston with the radial arms engaging the outer end, the stringers extending through the extended bore including the connecting rod, and the fingers lying within the grooves with the finger hooks engaging the interrupted portions to retain the clip in the piston bore.
