Engine Piston Kit
Cummins®

An engine piston kit is a set of components that includes the piston, piston rings, wrist pin and circlips. The kit is designed to replace the worn-out or damaged parts of an engine's piston assembly. The piston is the component that moves up and down in the cylinder bore, transferring energy from expanding gases to the crankshaft. Piston rings provide a seal between the piston and cylinder wall, preventing combustion gases from escaping into the crankcase. The wrist pin connects the piston to the connecting rod, allowing for vertical movement while maintaining proper alignment with other engine components. Circlips are used to secure various components in place within an engine assembly. A properly functioning engine piston kit ensures efficient combustion and optimum performance of an internal combustion engine. Part number 5472920 specifically refers to a particular type of engine piston kit used in certain models of trucks or other vehicles.
