Cylinder liner for Liebherr D904

The cylinder liner, part number 9177159, acts as the internal sleeve for the Liebherr D904 engine. It provides the working surface for the piston as it moves within the cylinder block. This component is essential for maintaining the integrity of the combustion chamber and facilitating the transfer of heat away from the piston and rings to the engine cooling system.

This liner is compatible with the Liebherr D904 engine. It is engineered to meet the specific dimensions and tolerances required for this engine series to ensure proper fitment and operation. When installed, it provides a consistent surface that allows the piston rings to maintain a seal, which is necessary for sustaining engine compression and managing oil consumption.

Cylinder liners are used in internal combustion engines to form the cylinder bore. They are designed to be replaced when the internal surface shows signs of wear or scoring, allowing for the restoration of the cylinder bore without requiring the replacement of the entire engine block. By providing a replaceable wear surface, the liner helps maintain engine efficiency and power output throughout the service life of the machinery.
