1118378 Piston & Liner Shim for Scania Engines

What does a piston & liner shim do?

This piston & liner shim is a critical adjustment component used to set the correct liner protrusion between the cylinder liner and the engine block seating surface. By providing a precise thickness, it ensures the cylinder head gasket receives the exact clamping pressure required for a high-pressure seal. This component is vital for maintaining combustion integrity in heavy-duty diesel engines during an overhaul.

Compatible engines and fitment

This specific shim is designed for Scania engines, specifically compatible with the DS11 engine series. It features an outside diameter of 153.70 mm, an inside diameter of 148.10 mm, and a thickness of 0.40 mm. Such precision components are essential for workshop technicians performing engine rebuilds to ensure long-term reliability.

Installation and maintenance

When replacing liners or performing a full engine overhaul, measuring the liner protrusion is mandatory to select the correct shim thickness. This 0.40 mm variant helps achieve the target clearance required by the manufacturer. Proper installation prevents leaks and ensures stable heat transfer across the sealing surfaces.

Selection guidance

Consult your authorized distributor to verify exact fitment requirements for your specific engine configuration.
