Cylinder liner for Perkins

The cylinder liner 4222128M1 serves as a replaceable sleeve inserted into the engine block to provide a defined sliding surface for the piston. It protects the engine block from direct contact with the piston and rings while managing the thermal and pressure loads generated during the combustion cycle. The internal surface is machined to ensure a seal with the piston rings, which maintains engine compression and manages oil consumption. By utilizing this component, maintenance teams can address cylinder bore wear without replacing the entire engine block.

This component is engineered for specific Perkins engine configurations. It functions as the primary interface between the reciprocating piston assembly and the cooling system of the engine block. Proper installation of the liner ensures that heat is transferred efficiently from the combustion chamber to the coolant passages, preventing localized overheating. As a critical engine component, it must be installed according to the manufacturer specifications to ensure correct clearance and sealing.
