Description
What does a piston & liner shim do?
This piston & liner shim is a critical adjustment component used to bring the cylinder liner protrusion into the exact target range within heavy-duty diesel engines. By ensuring the liner sits at the correct height relative to the block surface, this part allows the cylinder head gasket to maintain balanced clamping pressure, which is essential for preventing gas leaks and maintaining engine compression.Compatibility and application
This specific shim is compatible with Scania DS11 engines. It is engineered to withstand high cylinder pressures and provides a stable interface between the liner and the engine block seating surface. When performing an engine overhaul or replacing a liner, selecting the precise thickness is vital for long-term component integrity.Installation and maintenance
During installation, workshop technicians should ensure that all seating surfaces are thoroughly cleaned of any residue or corrosion to achieve accurate protrusion measurements. It is recommended to inspect the shim for any deformations before fitting and to always use a single shim of the correct grade rather than stacking multiple thin layers.Troubleshooting and selection
Regular inspection of the liner seating area during maintenance can help prevent improper sealing. For precise installation, always follow the manufacturer's torque specifications and tightening sequences to ensure the cylinder head is correctly clamped.OE cross-reference
1400 02 005 (Piston & Liner Shim) is the equivalent of the Scania OE number. This part directly replaces Scania OE number 1118377.Technical Specifications

FAQ
What is the purpose of a piston & liner shim?
A piston & liner shim is used to adjust the protrusion of a cylinder liner within the engine block, ensuring correct clamping force on the head gasket.
How is the thickness of this shim determined?
The 0.25 mm thickness must be selected based on measured liner protrusion values during an engine overhaul to ensure proper sealing.
Can I stack multiple shims to reach the required height?
No, it is critical to use a single shim of the correct thickness grade rather than stacking multiple thin shims to avoid improper load distribution.
What are the symptoms of an incorrectly fitted shim?
Improperly fitted shims can lead to uneven clamping pressure, resulting in gas leaks, coolant leaks, or premature cylinder head gasket failure.
What are the OE reference numbers of this part?
1400 02 005 directly replaces Scania OE number 1118377.
