Cylinder liner for Scania TD120

The cylinder liner 14-458840-00 is a cylindrical component that inserts into the engine block to provide a contact surface for the piston. It protects the engine block from the movement of the piston and the thermal and pressure conditions created during the combustion cycle. This liner facilitates the transfer of heat from the piston and combustion gases to the engine cooling system while maintaining a seal with the piston rings to preserve compression and prevent fluid leakage.

This part is compatible with the Scania TD120 engine. It is manufactured to meet the specific requirements of this engine model, ensuring proper fitment within the block.

Cylinder liners act as the primary interface between the reciprocating piston assembly and the stationary engine block. By providing a replaceable surface, they allow for the restoration of cylinder geometry during engine overhauls without requiring the replacement of the entire engine block. Proper installation ensures that the piston rings can maintain an effective seal, which is necessary for consistent engine power output and efficient operation.
