Cylinder liner for Mercedes-Benz

The cylinder liner, part number 005WN09, serves as the internal sleeve within the engine block where the piston travels. It provides a defined surface for the piston and its rings to move against during the combustion cycle. This component is engineered to maintain dimensional stability and surface finish, which are necessary for proper piston ring sealing and oil retention within the engine assembly.

This specific liner is designed for use in various Mercedes-Benz engine applications. It is manufactured to meet the required tolerances for fitment within the engine block, ensuring that the combustion chamber remains sealed and that heat transfer from the piston to the cooling system is managed effectively. Correct installation of this liner is necessary to maintain engine compression and support the reciprocating motion of the internal components.

Cylinder liners act as a replaceable wear surface in internal combustion engines. By housing the piston, they protect the engine block from direct friction and heat, allowing for easier maintenance when cylinder wall wear occurs. They are typically installed as a press-fit or slip-fit component depending on the engine design, facilitating the restoration of the cylinder bore to original specifications.
