Description
What does a piston and liner shim do?
This piston and liner shim is a critical component used to bring liner protrusion in heavy-duty diesel engines into the required target range. By providing the exact thickness needed, it ensures that the head gasket carries a balanced clamping load, which is essential for preventing gas leaks and subsequent gasket failures during engine operation.Compatibility and technical dimensions
This specific shim is designed for use with DS 8 engine systems. It features an outside diameter of 137.10 mm and an inside diameter of 132.50 mm, with a thickness of 0.25 mm to ensure precise fitment and performance under high-temperature conditions.Installation and maintenance guidance
For successful installation, ensure all surfaces are thoroughly cleaned of gasket residue or corrosion before fitting the shim to avoid false protrusion readings. It is recommended to measure each cylinder separately during the process to account for block wear variations. Always follow the manufacturer's specified torque sequences when reassembling the cylinder head.Ensuring engine reliability
Maintaining correct protrusion is vital for long-term engine reliability and preventing coolant or gas leakage into the crankcase.Technical Specifications

FAQ
What is the purpose of a piston and liner shim?
A shim is used to adjust the liner protrusion in a diesel engine, ensuring the head gasket receives a balanced load to prevent leaks.
How do I ensure the correct fitment for DS 8 engines?
Verify that the outside diameter (137.10 mm) and inside diameter (132.50 mm) match your specific liner requirements.
Can I stack two thin shims instead of using one thicker one?
No, it is best practice to use a single shim of the correct thickness rather than stacking multiple shims to ensure stability.
Why must I clean the surfaces before installation?
Cleaning ensures that residue or scale does not interfere with the measurement, preventing inaccurate liner protrusion readings.
