442 011 01 59 Mercedes-Benz Compatible Piston & Liner Shim

What does a piston & liner shim do?

This piston & liner shim is a critical adjustment component used to set the liner protrusion within the required specifications during an engine overhaul. By sitting between the cylinder liner and the block seating surface, it ensures the correct clamping pressure on the cylinder head gasket, which is vital for maintaining compression and preventing leaks in heavy commercial vehicle engines.

Compatibility and technical dimensions

This specific shim is compatible with Mercedes-Benz engines. It features an outside diameter of 153.50 mm, an inside diameter of 146.90 mm, and a thickness of 0.15 mm, making it suitable for applications requiring precise clearance adjustment in high-pressure environments.

Installation and maintenance guidance

For optimal engine performance, technicians should measure the liner protrusion before selecting the appropriate shim thickness from a graduated series. Proper installation of these high-strength components helps prevent head gasket failure and ensures long-term sealing integrity under heavy-duty operating conditions.

Selection for engine overhauls

Consult your authorized distributor to ensure this component matches your specific engine series requirements.
