Engine Piston Kit
Cummins®

The Engine Piston Kit with part number 3800838 is a component of the internal combustion engine found in trucks. It consists of a set of pistons, piston rings, and wrist pins that work together to compress fuel and air in the engine's cylinders. The kit is designed to fit specific engine models and comes with all the necessary components for installation. The piston is a cylindrical component that moves up and down inside the cylinder, transferring force from expanding gases to the crankshaft. Piston rings are installed around each piston to create a tight seal between the piston and cylinder wall, preventing oil leaks while ensuring optimal compression pressure. Wrist pins connect each piston to the connecting rod, which transfers motion from the pistons to the crankshaft, powering vehicle movement. Overall, this kit plays an essential role in maintaining proper engine performance by ensuring efficient combustion and preventing damage due to overheating or excessive wear over time.
