Cylinder liner for Cummins 4BTA

The cylinder liner with part number 14-047310-00 functions as a replaceable cylindrical sleeve inserted into the engine block of Cummins 4BTA and 6BTA engines. It provides a precise surface for the piston to travel along during the combustion cycle while protecting the surrounding engine block from direct contact and heat. By maintaining the integrity of this surface, the liner helps ensure proper compression and efficient engine operation.

This component is compatible with Cummins 4BTA and 6BTA engine models found in various industrial cranes and heavy machinery. It is engineered to meet the specific dimensional requirements of these engine series to ensure a correct fit within the cylinder bore. Proper installation of this liner is necessary to restore the sealing surface and guide the piston assembly accurately.

Cylinder liners serve as the primary wear surface in an internal combustion engine. They contain the combustion gases and facilitate the transfer of heat from the piston to the engine cooling system. Replacing worn liners is a standard maintenance procedure to restore engine compression and overall power output.
