Cylinder liner for Cummins 6CT

The cylinder liner, part number 14-740010-00, is installed within the engine block to provide the internal surface where the piston travels during operation. It acts as a barrier between the moving piston assembly and the engine block, managing the thermal environment and mechanical friction generated during the combustion cycle. This component is manufactured by Magrumape.

This specific liner is compatible with the Cummins 6CT engine. It maintains the internal dimensions required for proper piston clearance and ring sealing, which are necessary to preserve compression within the combustion chamber. By providing a controlled surface for the piston rings, the liner supports the overall efficiency of the engine block assembly.

Cylinder liners are used in internal combustion engines to form the cylinder walls. They facilitate heat transfer from the combustion process to the cooling system and provide a wear-resistant surface that can be replaced without requiring the replacement of the entire engine block. Proper installation ensures that the liner remains seated correctly under the pressure and thermal loads typical of heavy machinery engine operation.
