Description
What does a piston & liner shim do?
This piston and liner shim is a critical adjustment component used to position the cylinder liner protrusion within the precise target range required for heavy-duty diesel engines. By providing a specific thickness, this part ensures that the cylinder head gasket receives a balanced clamping load, which is essential for preventing gas leaks and maintaining engine compression.Compatibility and technical specifications
Designed for use in FH12 engines, this shim features an outside diameter of 158.90 mm, an inside diameter of 152.10 mm, and a thickness of 0.40 mm. These dimensions are vital for achieving the exact seating depth required during engine rebuilds or liner replacements in heavy commercial vehicles.Installation and maintenance guidance
For professional technicians performing engine overhauls, it is essential to measure the liner protrusion accurately before selecting the shim. This ensures the component compensates correctly for any variations in the block surface or liner height, maintaining the integrity of the combustion chamber seal.Importance of precise protrusion
When performing maintenance or engine repairs, always verify that the shim thickness matches the manufacturer's specifications to prevent premature gasket failure or improper cylinder sealing.Technical Specifications
