Cylinder liner for Mercedes-Benz OM407

The cylinder liner, part number 14-456330-00, is a cylindrical component installed within the engine block of Mercedes-Benz OM407 and OM409 engines. This component provides a precise sliding surface for the piston assembly, which separates the moving piston from the engine block structure. By housing the combustion process, the liner protects the engine block from direct friction and thermal stress during operation. It is engineered to maintain the necessary clearances for efficient engine performance and to facilitate heat transfer from the combustion chamber to the cooling system.

This component is compatible with Mercedes-Benz OM407 and OM409 engine models. Cylinder liners are critical for maintaining proper compression levels and ensuring an effective seal within the combustion chamber. In heavy machinery and industrial equipment, the liner acts as a replaceable interface that manages the mechanical wear associated with reciprocating piston movement. By providing a controlled surface for the piston rings, the liner helps maintain the structural integrity of the engine assembly during operation.
