Cylinder liner for Cummins 6CT

The cylinder liner 14-740030-00 serves as the internal sleeve for the piston in the Cummins 6CT engine. It creates a controlled surface for piston movement while shielding the engine block from the direct thermal and mechanical stresses of the combustion process. By maintaining the integrity of the cylinder wall, this component supports effective piston ring sealing and helps manage internal engine pressures.

This part is designed specifically for fitment in the Cummins 6CT engine, which is commonly found in construction machinery and heavy-duty vehicles. The liner is manufactured to meet the dimensional requirements of the engine block to ensure a precise fit and proper heat transfer during operation.

In internal combustion engines, cylinder liners act as the primary wear surface for the piston assembly. They are engineered to withstand the sliding friction of the piston rings and the high-temperature environment of the combustion chamber. A properly functioning liner is necessary to maintain compression levels and prevent oil consumption issues that can arise from worn or damaged cylinder surfaces.
