Cylinder liner for Cummins 6CT

The cylinder liner, identified by part number 89645110, is a cylindrical component installed within the engine block of the Cummins 6CT. It creates the internal wall of the cylinder, providing a precise surface for the piston to slide against during the combustion cycle. This component is manufactured by Cummins.

This liner is specifically engineered for the Cummins 6CT engine model. It functions as the primary interface for the piston rings, maintaining the seal required for effective combustion pressure. By housing the piston, the liner facilitates the transfer of heat generated during engine operation away from the combustion chamber and into the cooling system of the machine.

In internal combustion engines, cylinder liners serve to define the bore of the engine and protect the engine block from the friction and thermal stresses of the piston movement. They are designed to be replaceable, allowing for the restoration of the cylinder bore dimensions without needing to replace the entire engine block. Proper installation ensures that the piston maintains a tight seal, which is necessary for consistent engine power and efficiency.
