Description
What does a piston and liner shim do?
This piston and liner shim serves as a critical component in heavy-duty diesel engine assembly by precisely adjusting the liner protrusion within the cylinder block. By compensating for manufacturing tolerances or block wear, this shim ensures the cylinder liner sits at the exact height required to maintain a balanced clamping load on the head gasket, preventing gas leaks and potential engine failure.TD120 engine compatibility
Designed specifically for use in TD120 engines, this component features an outside diameter of 157.10 mm and an inside diameter of 151.10 mm with a thickness of 0.10 mm. This specific dimension is essential for maintaining the integrity of the combustion seal under high-pressure operating conditions.Installation and maintenance
For professional installation, technicians should ensure that all seating surfaces are thoroughly cleaned of residue or corrosion before fitting. It is vital to measure each cylinder individually to account for variations across the block. Always follow the manufacturer's specified torque sequence and tightening values during the assembly process to ensure long-term reliability.Troubleshooting and assembly tips
When performing engine overhauls, inspecting the shim for any deformation is necessary, as a single, correctly sized shim should always be used rather than stacking multiple thin layers.Technical Specifications

FAQ
What is the purpose of a piston and liner shim?
A shim is used to set the correct liner protrusion in a cylinder block, ensuring the head gasket receives a balanced clamping load to prevent leaks.
What are the dimensions of this specific shim?
This shim features an outside diameter of 157.10 mm, an inside diameter of 151.10 mm, and a thickness of 0.10 mm.
Can I stack multiple thin shims together?
It is recommended to use a single shim of the correct thickness grade rather than stacking multiple thin shims to ensure stability.
Why must surfaces be cleaned before installation?
Cleaning ensures that residue or scale does not skew protrusion readings, which could lead to incorrect seating and gasket failure.
