Cylinder liner for Scania TD120

The cylinder liner, part number 88660110, acts as the internal sleeve for the cylinder bore within the Scania TD120 engine. It provides the necessary surface for the piston and its rings to travel during operation. By maintaining the integrity of the cylinder wall, this component ensures the combustion chamber remains sealed, which is necessary for maintaining compression and engine efficiency. It also plays a role in transferring heat away from the combustion process to the engine block cooling system.

This component is compatible with the Scania TD120 engine. It is designed to meet the specific dimensional and tolerance requirements of this engine series. Proper installation of the liner is necessary to ensure the correct fit for the piston assembly and to maintain the required clearance for lubrication. When replacing this component, it is standard practice to inspect the piston and rings to ensure the entire assembly meets the engine's operational specifications.

In internal combustion engines, cylinder liners provide a replaceable surface for the piston to slide against. This design allows for the restoration of the cylinder bore without needing to replace the entire engine block. Liners are positioned within the engine block and are exposed to high temperatures and pressures during the power stroke.
