Cylinder liner for Scania TD120

The cylinder liner, part number 470836, serves as the internal sleeve for the Scania TD120 engine. It creates the precise cylindrical surface required for the piston to move during the combustion cycle. By acting as a replaceable interface, this component protects the engine block from direct contact with the piston rings and the heat generated during operation. It maintains the necessary seal to ensure proper compression and prevents the migration of oil or combustion gases.

This component is engineered for fitment within the Scania TD120 engine assembly. It is designed to match the specific bore dimensions of the engine block to ensure a correct fit. Proper installation of the liner is necessary to maintain the integrity of the cylinder wall and support the movement of the piston assembly throughout the engine's operational range.

Cylinder liners are used in internal combustion engines to provide a renewable surface for piston movement. They allow for the restoration of the cylinder bore without requiring the replacement of the entire engine block. By managing thermal transfer and friction, the liner helps maintain the efficiency of the power unit.
