Description
What does a piston & liner shim do?
This piston & liner shim serves as a critical adjustment component within the engine cylinder assembly. It is fitted between the cylinder liner and the engine block to precisely control liner protrusion. Proper protrusion is essential for ensuring the correct clamping pressure on the cylinder head gasket, which directly impacts engine sealing and compression efficiency.Compatibility and application
This specific component is compatible with Mercedes-Benz heavy commercial vehicle engines. It is designed to meet strict tolerances required for heavy-duty diesel applications, including trucks and buses. The shim features an outside diameter of 153.50 mm, an inside diameter of 146.90 mm, and a thickness of 0.50 mm.Installation and maintenance guidance
During engine overhauls or liner replacements, technicians must measure the existing protrusion to select the correct thickness from graduated series. Using the correct shim ensures optimal sealing under high cylinder pressures and prevents premature gasket failure or oil leakage.Troubleshooting and selection
Consult your authorized distributor to ensure correct fitment for your specific engine series.OE cross-reference

FAQ
What is the purpose of a piston & liner shim?
The shim is used to adjust the liner protrusion height in the engine block, ensuring the cylinder head gasket receives the correct clamping force for reliable sealing.
How is the correct shim thickness determined?
Technicians must measure the current liner protrusion during an overhaul to select the appropriate thickness, such as this 0.50 mm variant, to achieve target specifications.
Can these shims be used in light commercial vehicles?
No, these components are specifically engineered for heavy commercial vehicle engines, including trucks and buses, to withstand high combustion pressures.
What are the symptoms of incorrect liner shim installation?
Improper protrusion caused by incorrect shimming can lead to cylinder head gasket failure, loss of compression, or coolant/oil leakage.
What are the OE reference numbers of this part?
1100 02 027 directly replaces Mercedes-Benz OE numbers 4420110059, 4420110159, 4420110259.
