3800879
Piston Kit
Cummins®

A piston kit is an essential component of a truck engine that converts the energy generated during combustion into mechanical motion. The part number 3800879 refers to a specific piston kit model that includes all the necessary components for replacing damaged or worn out pistons. This kit typically consists of one or more pistons, piston rings, wrist pins, and retaining clips. The pistons are responsible for compressing fuel and air in the engine cylinder and transferring this energy to the crankshaft via connecting rods. Piston rings provide a seal between the piston and cylinder walls, preventing leakage of gases during combustion. Wrist pins connect the piston to the connecting rod, enabling it to move up and down in sync with the other cylinders. Retaining clips secure these components in place within their respective grooves on the piston assembly. A high-quality piston kit like part number 3800879 ensures optimal engine performance by maintaining proper compression ratios and minimizing oil consumption while extending engine life.
