Cylinder liner for Perkins 4.108

This cylinder liner, identified by part number 3.144/, serves as the internal sleeve for the Perkins 4.108 engine. It creates the primary surface for the piston rings to seal against during the combustion cycle, maintaining the necessary cylinder pressure for engine operation. By acting as the interface between the piston and the engine block, the liner manages the heat transfer from the combustion process to the cooling system while preventing direct friction between the moving piston and the engine block casting.

The component is engineered specifically for the Perkins 4.108 engine series. It is installed within the cylinder bore to restore the internal diameter to original specifications, which is necessary when the engine block shows signs of wear or scoring. Proper installation ensures that the piston maintains a correct clearance, which is vital for oil control and compression efficiency. Cylinder liners of this type are used in internal combustion engines to provide a replaceable wear surface, allowing for the maintenance of the engine block without requiring a full replacement of the main casting when internal surfaces become worn.
