Cylinder liner for Scania TD40A

The cylinder liner with part number 89162110 functions as the internal sleeve for the combustion chamber in the Scania TD40A engine. It provides a precise surface for the piston and piston rings to move against while maintaining the structural integrity of the cylinder block. This component is designed to facilitate heat transfer from the combustion process to the cooling system, helping to manage thermal loads within the engine assembly.

This part is compatible with the Scania TD40A engine model. It is engineered to meet the specific dimensional requirements of this engine block, ensuring proper fitment and alignment during engine overhauls or repairs. The liner maintains the necessary clearance for the piston assembly to operate within the specified tolerances for compression and oil control.

In internal combustion engines, the cylinder liner acts as a replaceable wear surface that protects the engine block from direct contact with the piston rings. By providing a controlled surface finish, the liner ensures an effective seal for the combustion gases, which is necessary for maintaining engine power and operational efficiency.
