Description
What does a piston and liner shim do?
This piston and liner shim is a critical component used to adjust the protrusion of the cylinder liner within the engine block. By providing a precise thickness, it ensures that the clamping force on the cylinder head gasket remains within the required technical specifications, which is vital for maintaining compression and preventing leaks in heavy-duty diesel engines.Compatibility and application
This specific component is designed for Mercedes-Benz engines. It features an outside diameter of 153.50 mm and an inside diameter of 146.90 mm with a thickness of 0.50 mm, making it suitable for applications requiring precise clearance adjustment. These shims are essential during engine overhauls to compensate for liner height variations.Installation and maintenance
For correct installation, technicians must measure the liner protrusion accurately before selecting the appropriate shim thickness. Ensuring the correct fitment helps maintain high cylinder pressure and prevents premature gasket failure. Proper maintenance involves checking liner stability during routine engine inspections.Selection guidance
Consult your authorized distributor to ensure this shim matches your specific engine series requirements.OE cross-reference
