Cylinder liner for Cummins 611/6

The cylinder liner 14-740090-00 functions as the internal sleeve for the engine block, providing a sliding surface for the piston assembly. It is engineered to withstand the mechanical forces of combustion and the thermal loads generated during the engine cycle. By maintaining the integrity of the cylinder wall, this component supports the piston rings in creating a seal, which is necessary for maintaining compression and proper combustion efficiency within the Cummins 611/6 61CID engine.

This component is compatible with the Cummins 611/6 61CID engine model. The actual manufacturer of this part is Cummins. Proper installation and alignment are required to ensure the liner maintains its dimensional stability and sealing properties during engine operation.

In heavy machinery engines, cylinder liners are used to define the combustion chamber and manage heat transfer from the piston to the cooling system. They provide a replaceable wear surface that can be serviced during engine overhauls to restore the original bore geometry and surface finish, which helps in managing oil consumption and blow-by gases throughout the service life of the engine block.
