Description
What does a piston & liner shim do?
This precision component is essential for setting the correct liner protrusion within a heavy-duty diesel engine's combustion chamber assembly.Technical specifications and fitment
The shim is fitted between the cylinder liner and the block seating surface to ensure the liner stands at the required height above the block deck. This specific thickness of 0.30 mm allows for a balanced clamping load across the head gasket, which is critical for preventing gas leaks and ensuring long-term engine reliability after an overhaul.Installation and maintenance guidance
For installation, it is vital to clean all surfaces thoroughly to remove any scale or residue that could skew protrusion readings. Technicians should measure each cylinder individually, as block wear can vary across the engine block. Using a single shim of the correct grade is preferred over stacking multiple thin pieces to maintain structural integrity under high pressure.Critical assembly notes
When replacing liners, always inspect the seating surface and ensure that all associated seals are renewed to prevent coolant contamination in the crankcase. Check the compatibility list for your specific engine requirements.Technical Specifications

FAQ
What is the purpose of a piston & liner shim?
A shim is used to adjust the liner protrusion height, ensuring the cylinder head gasket receives the correct clamping pressure for a reliable seal.
How should I select the correct shim thickness?
Thickness must be selected based on precise measurements of the liner protrusion after it is seated in the block to ensure proper combustion chamber sealing.
Can I stack two thin shims instead of one thick one?
It is recommended to use a single shim of the correct thickness grade rather than stacking multiple thin pieces to maintain stability and load distribution.
What should I check before installing a new shim?
Ensure all surfaces are completely clean of residue or corrosion and inspect the shim for any signs of deformation or burrs before fitting.
