Description
What does a piston & liner shim do?
This piston and liner shim is a critical adjustment component used to manage the protrusion of the cylinder liner within the engine block. By providing a precise thickness, it ensures the clamping pressure on the cylinder head gasket is within the required specifications, which is essential for maintaining proper engine sealing and compression.Compatibility and technical specifications
This specific shim 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 0.30 mm to meet exact technical requirements during engine rebuilds.Installation and maintenance guidance
During an engine overhaul or when replacing a cylinder liner, technicians must measure the liner protrusion to select the correct shim thickness. Using the appropriate grade ensures that the combustion chamber remains sealed under high pressure and prevents leaks that could lead to coolant or oil contamination.Importance of precise selection
Proper selection of these shims is vital for long-term engine reliability in heavy commercial vehicles. Always verify the required thickness against measured liner height before installation to ensure optimal performance.OE cross-reference
