Description
This piston & liner shim is a decisive component used to bring cylinder liner protrusion into the precise target range within heavy-duty diesel engines. By providing an exact thickness, it ensures the cylinder head gasket receives a balanced clamping load, which is critical for preventing gas leaks and repeat gasket failures during engine operation.
These shims are essential for maintaining engine sealing integrity during overhauls or liner replacements in heavy commercial vehicle engines. They are designed to withstand high temperatures and intense clamping forces, maintaining their dimensional stability under extreme operating conditions.
For proper installation, ensure all seating surfaces are thoroughly cleaned of residue or corrosion to avoid false protrusion readings. It is recommended to measure each cylinder individually and use a single shim of the correct thickness rather than stacking multiple thin pieces. Always follow the manufacturer's specific torque sequence and values during assembly.
Consult your authorized distributor for compatibility with specific engine models.

FAQ
What is the function of a piston & liner shim?
It adjusts the liner protrusion to ensure the cylinder head gasket receives the correct clamping load, preventing leaks.
How should I measure the required shim thickness?
Protrusion should be measured at every liner change using precision tools; always refer to the service manual for target values.
Can I stack multiple thin shims together?
No, you should use a single shim of the correct thickness grade to ensure stability and prevent uneven loading.
Why is surface cleanliness important during installation?
Any residue or scale on the block shoulder can cause inaccurate protrusion readings and lead to incorrect shim selection.
