Cylinder liner for Perkins

The cylinder liner is a cylindrical component installed into the engine block to house the piston as it travels through its combustion cycle. It serves as the primary contact surface for the piston and rings, protecting the engine block from direct friction and the intense heat generated during operation. By maintaining a precise internal diameter and surface finish, this component ensures an effective seal for the piston rings, which is necessary to maintain compression and overall engine efficiency. It also facilitates the transfer of thermal energy from the combustion chamber to the engine cooling system.

This specific component, part number 31358326, is engineered for compatibility with various Perkins engine configurations. It is manufactured to meet the original design specifications for fitment within the engine block. Proper installation of the liner is required to ensure the integrity of the cylinder assembly and to support the operational requirements of the engine. Cylinder liners are commonly used in internal combustion engines to allow for the maintenance of the cylinder bore without requiring the replacement of the entire engine block, providing a replaceable wear surface that can be serviced during engine overhauls.
