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 precise target range during engine overhauls. By compensating for slight variations in the engine block seating surface, it ensures that the cylinder head gasket receives the exact clamping force required to prevent gas leaks and maintain compression under high cylinder pressures.Compatibility and engine fitment
This specific shim is designed for Scania engines, particularly within the DS11 series. It features an outside diameter of 153.70 mm and an inside diameter of 148.10 mm, with a thickness of 0.20 mm, making it suitable for heavy-duty diesel engine maintenance where precise liner seating is mandatory.Installation and maintenance guidance
For successful installation, technicians should ensure all contact surfaces are thoroughly cleaned of residue or corrosion to avoid inaccurate protrusion readings. It is vital to use a single shim of the correct thickness rather than stacking multiple layers, as stacking can lead to uneven load distribution and potential gasket failure.Troubleshooting and selection
When performing an engine rebuild, always measure each cylinder individually, as block wear can vary between cylinders. Proper selection of this shim ensures the long-term integrity of the engine's sealing system in heavy commercial vehicle applications.OE cross-reference
1400 02 004 (Piston & Liner Shim) is the equivalent of the Scania OE number. This part directly replaces Scania OE number 1118376.Technical Specifications

FAQ
What is the purpose of a piston & liner shim?
It is used to adjust the liner protrusion height on the engine block, ensuring the cylinder head gasket is clamped with the correct force to prevent leaks.
Can I stack two thin shims to reach the required thickness?
No, you should always use a single shim of the correct thickness grade to ensure a stable and even load distribution on the gasket.
Why must I clean the block surface before installing the shim?
Any scale, corrosion, or residue on the block shoulder can cause inaccurate protrusion measurements, leading to improper sealing.
How do I know if this shim fits my Scania engine?
This shim is designed for Scania DS11 applications with a 153.70 mm outside diameter and a 0.20 mm thickness; always verify against service manuals.
What are the OE reference numbers of this part?
1400 02 004 directly replaces Scania OE number 1118376.
