Cylinder liner for Perkins

The cylinder liner 89514190 serves as the internal sleeve for the piston assembly within the engine block. By providing a controlled surface for the piston to move against, it protects the engine block from direct friction and the thermal stresses generated during the combustion cycle. This component allows for the restoration of the cylinder bore surface without needing to replace the entire engine block, facilitating maintenance during engine overhauls.

This part is compatible with various Perkins engine configurations. It is manufactured by Perkins to meet specific dimensional requirements for bore size and wall thickness, ensuring a precise fit within the block and proper alignment with the piston rings.

In internal combustion engines, cylinder liners are used to maintain the integrity of the combustion chamber. They ensure that the piston rings can maintain a consistent seal, which is necessary to achieve the required compression ratios and prevent oil consumption. By managing the heat transfer from the combustion process to the cooling system, the liner helps maintain stable operating temperatures for the reciprocating components.
