Description
What does a piston and liner shim do?
This piston and liner shim is a critical adjustment component used to set the correct liner protrusion within a heavy-duty diesel engine. By being fitted between the cylinder liner and the engine block seating surface, it ensures the cylinder head gasket receives the exact clamping load required for a high-pressure seal.Technical specifications and fitment
This specific component is engineered for DS 8 engine applications, featuring an outside diameter of 137.10 mm and an inside diameter of 132.50 mm with a thickness of 0.40 mm. It is manufactured from high-strength components designed to withstand extreme thermal cycles and high combustion pressures without losing its dimensional integrity.Installation and maintenance guidance
For workshop technicians performing engine overhauls, selecting the correct shim thickness is vital for preventing gas leaks or repeated gasket failures. During installation, ensure all seating surfaces are perfectly clean to allow the shim to provide a balanced load across the gasket surface.Ensuring proper engine sealing
Always verify the required protrusion measurement against the manufacturer's service specifications before selecting a shim grade to ensure long-term engine reliability.Technical Specifications

FAQ
What is the function of a piston and liner shim?
The shim is used to adjust the liner protrusion to a specific range, ensuring the cylinder head gasket is clamped with the correct pressure to prevent leaks.
How do I know if I need a new shim?
Shims should be inspected or replaced whenever a cylinder liner is replaced or during a complete engine overhaul to ensure precise seating.
What are the dimensions of this specific shim?
This component has an outside diameter of 137.10 mm, an inside diameter of 132.50 mm, and a thickness of 0.40 mm.
Why is thickness precision important for shims?
Precision thickness is essential because even minor deviations can lead to incorrect liner protrusion, which can cause head gasket failure or loss of compression.
