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 exact target range. By providing a precisely controlled thickness, it ensures the head gasket carries a balanced clamping load, which is essential for preventing gas leaks and repeat gasket failures under high pressure.Engine compatibility and dimensions
This specific component is designed for use in TD70 engines. It features an outside diameter of 126.60 mm and an inside diameter of 120.10 mm with a thickness of 0.25 mm to maintain the required sealing geometry within the engine block.Installation and maintenance guidance
For successful installation, ensure all surfaces are thoroughly cleaned of gasket residue or corrosion before fitting to avoid skewed protrusion readings. It is recommended to measure each cylinder separately, as block wear can vary across the engine, and always verify that the shim is free from burrs or deformations before assembly.Troubleshooting and assembly tips
When performing maintenance, always follow the manufacturer's specified tightening sequence and torque values to ensure the shim performs its role in maintaining cylinder sealing integrity.Technical Specifications

FAQ
What is the purpose of a piston and liner shim?
A shim is used to adjust the liner protrusion within a specific target range, ensuring the head gasket receives a balanced clamping load to prevent leaks.
What are the dimensions of this specific shim?
This component features an outside diameter of 126.60 mm, an inside diameter of 120.10 mm, and a thickness of 0.25 mm.
Why must surfaces be cleaned before installing a new shim?
Residue or corrosion on the block shoulder can skew protrusion readings, leading to incorrect installation and potential engine failure.
Can multiple thin shims be stacked together?
It is best practice to use a single shim of the correct thickness grade rather than stacking multiple thin shims to ensure stability.
