Cylinder liner for Scania D13A/ B

The cylinder liner, part number 21334768, serves as the internal wall of the engine cylinder where the piston assembly operates. It creates the necessary seal for the combustion chamber and facilitates the transfer of heat away from the piston and rings toward the engine cooling system. This component is engineered specifically for the Scania D13A and D13B engine series to ensure precise fitment within the engine block.

Proper installation of the cylinder liner is necessary to maintain engine compression and prevent the leakage of combustion gases or lubricating oil. The internal surface is finished to support the lubrication of the piston rings as they move through the stroke. Maintaining the integrity of this liner is important for the overall operational efficiency of the engine. When replacing this component, ensure that the cylinder bore and seating surfaces are clean and free of debris to allow for a correct seal and proper thermal conductivity.
