Description

What does a piston and liner shim do?

This piston and liner shim serves as a critical adjustment component within the cylinder assembly of heavy-duty diesel engines. By being fitted between the cylinder liner and the engine block seating surface, it allows technicians to bring the liner protrusion into the exact target range required for proper sealing.

Compatibility and technical dimensions

This specific part is designed for Mercedes-Benz applications. 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 a Ø 128 specification. Precise thickness selection is essential to manage the clamping pressure applied to the cylinder head gasket.

Installation and maintenance guidance

During engine overhauls or when replacing liners, workshop technicians must measure the existing protrusion to select the correct shim thickness. Ensuring the correct fitment helps prevent oil leaks and maintains compression stability under high cylinder pressures.

Selection for engine overhauls

Check the compatibility list to ensure this component meets your specific engine requirements.
