Cylinder liner for Perkins

The cylinder liner, part number 31358339, serves as the internal sleeve for the engine block in Perkins equipment. It provides a precise sliding surface for the piston and its rings, shielding the cylinder block structure from the direct friction, heat, and internal pressures generated during the combustion process. This component is engineered to maintain the necessary structural integrity for the reciprocating motion of the piston assembly.

This liner facilitates the transfer of thermal energy from the combustion chamber to the engine cooling system to assist in maintaining stable operating temperatures. It is a standard component used during engine overhauls or major repairs to restore compression levels and manage oil consumption within the cylinder. The part is manufactured to meet the specific dimensional requirements of the Perkins engine block to ensure a correct fit and alignment.

Cylinder liners are used in internal combustion engines to form the cylinder wall. They allow for the replacement of the wear surface without needing to replace or machine the entire engine block. By providing a controlled environment for the piston, the liner helps maintain the seal between the combustion chamber and the crankcase, which is necessary for efficient engine operation.
