Engine Piston Kit
Cummins®

The Engine Piston Kit, with Part Number 3803756, is an essential component of the truck's combustion engine. It includes a piston, piston rings, and wrist pins that work together to convert the pressure generated by the fuel and air mixture into mechanical energy. The piston is a cylindrical device that moves back and forth inside the engine cylinder bore. The piston rings provide a tight seal between the piston and cylinder walls to prevent oil from entering the combustion chamber while also keeping exhaust gases from escaping into the crankcase. The wrist pin connects the piston to the connecting rod which transfers power to the crankshaft. A damaged or worn-out Engine Piston Kit can cause poor engine performance, decreased fuel efficiency, and even complete engine failure. Therefore, it is important to regularly inspect and replace this component as needed for optimal truck performance.
