Cylinder liner for Perkins

The cylinder liner, identified by part number 14-045822-00, acts as the internal sleeve for the piston within a Perkins diesel engine. Installed directly into the engine block, it creates the chamber where combustion occurs and provides a controlled surface for the piston rings to slide against during operation. This component is essential for maintaining the integrity of the combustion space and ensuring proper movement of the piston assembly.

This specific liner is designed for use in various Perkins diesel engine configurations found in heavy machinery and industrial cranes. It functions to contain the pressure generated during the power stroke while facilitating heat transfer from the piston to the engine cooling system. By maintaining the correct clearance between the piston and the cylinder wall, the liner helps preserve engine compression and oil control.

In any internal combustion engine, the cylinder liner serves as the primary wear surface for the piston rings. It must be precisely machined to ensure a seal that prevents gas blow-by and oil consumption. Regular inspection of the liner surface is standard practice during engine overhauls to confirm that the bore remains within specified tolerances for diameter and roundness.
