Cylinder liner for Perkins

The cylinder liner, part number 31358349, is installed within the engine block to provide a controlled sliding surface for the reciprocating piston. It acts as the primary interface between the piston assembly and the engine block, managing the thermal and mechanical stresses generated during the combustion cycle. By housing the piston, the liner facilitates the transfer of heat from the combustion chamber to the engine cooling system while maintaining the necessary seal for compression.

This component is designed for use in specific Perkins diesel engine configurations. It serves to protect the engine block from direct wear and facilitates the maintenance of internal tolerances required for efficient engine operation. The precision of the liner surface is intended to ensure proper interaction with piston rings, which supports consistent compression and oil control throughout the operating cycle of the machine.
