Cummins 5669232F Piston Assembly

The Cummins 5669232F is a two-piece articulated piston assembly designed for the XPI fuel system platforms. It comprises a forged steel crown for high strength and thermal resistance, joined to an aluminum alloy skirt for reduced reciprocating mass and improved scuff resistance. The piston incorporates an oil cooling gallery for effective thermal management under high cylinder pressures. This assembly supersedes part numbers 4955160, 5267632, 4897512, and 5332597. It is engineered to meet original equipment specifications for compression ratio, ring land geometry, and pin bore finish. The kit typically includes the piston body, piston pin, retainer clips, and a standard ring set (two compression rings, one oil control ring). It serves as a direct replacement for in-frame overhauls on EPA 2010, 2013, and 2017 emission certified engines.
