Cylinder liner for Scania 123 FL

The cylinder liner with part number 89549110 serves as the internal sleeve for the engine block where the piston travels. It creates the combustion chamber wall, facilitating the compression process while allowing for the transfer of heat from the combustion cycle to the engine cooling system. This component is engineered to maintain a precise clearance with the piston rings to support the overall mechanical operation of the engine.

This part is compatible with the Scania 123 FL engine. It is designed to meet the specific dimensional requirements of this engine block to ensure a correct fit during assembly. Proper installation of the liner is necessary to maintain the seal between the piston and the cylinder wall, which is essential for preserving engine compression and preventing oil bypass.

Cylinder liners are used in internal combustion engines to provide a replaceable wear surface for the piston. By housing the piston assembly, the liner protects the engine block from direct contact with the combustion process and moving components. This allows for easier maintenance and restoration of the cylinder bore surface without needing to replace the entire engine block.
