Cylinder liner for Cummins 4BTA

The cylinder liner with part number 14-047313-00 serves as a critical component within the engine block of Cummins 4BTA and 6BTA power units. This cylindrical sleeve is inserted into the block to provide a defined sliding surface for the piston. It functions as a protective barrier that manages the friction and heat generated during piston movement while containing the high pressures produced during the combustion process. By acting as the interface between the piston and the engine block, it prevents direct contact and protects the block from wear.

This component is compatible with Cummins 4BTA and 6BTA engines commonly found in industrial cranes and heavy construction machinery. The surface finish of the liner facilitates an effective seal with the piston rings, which is necessary for maintaining proper compression and managing oil consumption within the cylinder assembly.

Cylinder liners are used in internal combustion engines to provide a replaceable wear surface for the piston. They assist in heat transfer from the combustion chamber to the engine cooling system and maintain the structural integrity of the cylinder bore over the operational life of the engine.
