Description
This piston and liner shim is a critical component used to adjust the liner protrusion within heavy-duty diesel engines to the exact target range. By fitting this thin ring between the cylinder liner and the engine block seating surface, technicians can ensure that the cylinder head gasket receives a balanced clamping load, which is vital for preventing gas leaks and repeat gasket failures.
This specific shim is designed for application in DS 8 engines. It features an outside diameter of 137.10 mm and an inside diameter of 132.50 mm with a thickness of 0.20 mm. These dimensions are essential for maintaining the correct seal within the combustion chamber during engine overhauls or liner replacements.
For successful installation, ensure all mating surfaces are thoroughly cleaned of residue, scale, or corrosion to prevent false protrusion readings. It is recommended to measure each cylinder individually, as block wear varies between cylinders. Always follow the manufacturer-specified tightening sequence and torque values when reassembling the cylinder head to maintain system integrity.
Proper selection of the correct thickness grade is mandatory to avoid improper clamping pressure or insufficient sealing.

FAQ
What is the function of a piston and liner shim?
A liner shim adjusts the liner protrusion in a heavy-duty engine to ensure the cylinder head gasket experiences the correct clamping load, preventing leaks.
How do I know if I need a new shim?
When replacing a cylinder liner, a new shim should be measured and fitted to match the specific protrusion requirements of the engine block.
Can I stack two thin shims together?
It is best practice to use a single shim of the correct thickness rather than stacking multiple thinner shims to ensure stability.
Why is surface cleanliness important during installation?
Any residue or corrosion on the block shoulder can cause inaccurate protrusion measurements, leading to incorrect shim selection.
