1100 02 023 Mercedes-Benz Piston & Liner Shim

What does a piston & liner shim do?

This piston & liner shim is a critical adjustment component used during engine overhauls to manage liner protrusion. By being placed between the cylinder liner and the block seating surface, it ensures the liner sits at the precise height required for optimal compression and gasket clamping pressure. Using high-strength components, this shim maintains stability under the high cylinder pressures typical of heavy-duty diesel engines.

Compatibility with Mercedes-Benz engines

This specific shim is compatible with Mercedes-Benz engines. It is engineered to meet the strict requirements of heavy commercial vehicle engine rebuilding, ensuring that the clearance between the liner and the block remains within technical tolerances. It is a vital part for workshop technicians performing top-end engine overhauls.

Installation and maintenance guidance

When installing this shim, technicians should verify the measured liner height to confirm that the 0,20 mm thickness is the correct match for the current protrusion requirements. Proper seating is essential to prevent leakage or improper gasket compression. Always check for surface cleanliness on the block seating area before final assembly.

Importance of correct thickness selection

Selecting the correct thickness grade is decisive for engine sealing and long-term reliability. A precise fit helps prevent oil seepage and maintains consistent compression throughout the service life of the engine.
