Cylinder liner for Iveco TUMOSAN

The cylinder liner fits into the engine block to provide a sliding surface for the piston during the combustion cycle. It acts as a replaceable interface that contains the combustion gases and facilitates heat transfer from the piston assembly to the engine cooling system. By maintaining the integrity of the cylinder bore, this component supports proper compression and oil control within the internal combustion engine.

This part 89608190 is compatible with Iveco TUMOSAN engines. It is a precision-machined component intended for engine rebuilds, allowing for the restoration of the cylinder wall surface without requiring the replacement of the entire engine block. The liner ensures a consistent seal with the piston rings to maintain engine performance.

Cylinder liners serve as the primary wear surface in an engine block. They are engineered to withstand the mechanical forces and thermal loads present during operation. Replacing the liner is a standard procedure during engine overhauls to return the cylinder geometry to factory specifications and ensure the continued operation of the power unit.
