Description
What does a piston & liner shim do?
This piston and liner shim is a critical component used to adjust the liner protrusion within the cylinder block of heavy-duty diesel engines. By filling the gap between the liner flange and the block seating surface, it ensures that the cylinder head experiences a balanced clamping load, which is essential for preventing gas leaks and protecting the head gasket.Compatibility and technical specifications
Specifically designed for DS 8 engine applications, this shim features an outside diameter of 137.10 mm and an inside diameter of 132.50 mm with a thickness of 0.10 mm. Using a single shim of the correct thickness is vital for maintaining precise tolerances across all cylinders.Installation and maintenance guidance
For successful installation, technicians should ensure all surfaces are thoroughly cleaned of residue or corrosion before fitting. It is recommended to measure each cylinder individually, as block wear can vary, and to always follow the manufacturer's specified torque sequence during assembly.Troubleshooting and assembly tips
Regular inspection of liner seating during engine overhauls helps prevent coolant leaks into the crankcase and ensures long-term component reliability.Technical Specifications

FAQ
What is the function of a piston and liner shim?
The shim is used to set the correct liner protrusion in heavy-duty diesel engines, ensuring the head gasket receives a proper clamping load to prevent leaks.
What are the dimensions of this specific shim?
This shim has an outside diameter of 137.10 mm, an inside diameter of 132.50 mm, and a thickness of 0.10 mm.
Can I stack multiple thin shims together?
It is best practice to use a single shim of the correct thickness rather than stacking multiple thin shims to ensure stability and precision.
How should I prepare surfaces before installation?
Surfaces must be cleaned thoroughly of any gasket residue, scale, or corrosion to ensure accurate protrusion measurements and proper seating.
