Cylinder liner for Scania MD70B

The cylinder liner 466865 functions as the internal sleeve for the Scania MD70B engine block. It creates the primary surface for the piston and its rings to travel against during the combustion cycle. By forming the wall of the combustion chamber, this component manages the transfer of heat from the piston and combustion gases into the engine cooling system.

This part is compatible with the Scania MD70B engine. It maintains the internal dimensions required for proper piston movement and compression sealing within the engine assembly. The precision of the liner surface is necessary for the interaction between the piston rings and the cylinder wall.

In heavy machinery engines, cylinder liners provide a replaceable wear surface for the cylinder bore. They are installed into the engine block to allow for efficient heat dissipation and to maintain the tight tolerances required to prevent blow-by and oil consumption. Proper installation ensures the engine maintains its intended compression and operational efficiency.
