Description
What does a piston & liner shim do?
This piston & liner shim serves as a critical adjustment component within the engine block assembly. It is positioned between the cylinder liner and the block seating surface to achieve the exact liner protrusion required for proper cylinder head gasket clamping pressure. Using high-strength components ensures that the seal remains intact even under the intense thermal and pressure cycles typical of 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 0.40 mm, making it suitable for applications requiring an Ø 128 specification profile. Such precision is vital for maintaining engine compression and preventing coolant or oil leaks through the liner interface.Installation and maintenance guidance
When performing an engine overhaul or replacing a cylinder liner, technicians must measure the existing protrusion to select the correct thickness grade. Installing a shim with an incorrect thickness can lead to improper gasket compression or excessive liner movement. Always verify the required clearance before installation to ensure long-term engine reliability.Selection for engine overhauls
Consult your authorized distributor for further assistance regarding fitment and technical selection.OE cross-reference
