Cylinder liner for Perkins T4.40

The cylinder liner, part number 3135X042, is a critical engine component for the Perkins T4.40. It is installed within the engine block to provide a precise sliding surface for the piston. This component facilitates the transfer of heat from the piston and combustion gases into the engine cooling system while maintaining a seal for the combustion chamber.

This liner is compatible with the Perkins T4.40 engine model. It is manufactured to meet the specific dimensional requirements of this engine series. Proper installation of the cylinder liner is necessary to maintain engine compression and support the movement of the piston and rings during operation.

In internal combustion engines, cylinder liners act as the primary contact surface for piston rings. They are responsible for containing the pressure generated during the combustion cycle and managing friction as the piston reciprocates. By providing a replaceable surface, liners allow for the restoration of cylinder geometry without requiring the replacement of the entire engine block.
