Description
What does a piston and liner shim do?
This precision-engineered piston and liner shim is a critical component used to adjust the liner protrusion within heavy-duty diesel engines. By providing a precise thickness of 0.15 mm, it ensures the cylinder liner sits at the exact height required to maintain balanced clamping pressure on the head gasket, preventing gas leaks and potential engine failure.Compatibility and application
This specific shim is compatible with TD70 engine applications. It features an outside diameter of 126.60 mm and an inside diameter of 120.10 mm, making it an essential part for engine overhauls where precise liner seating is mandatory to ensure long-term structural integrity.Installation and maintenance guidance
During installation, workshop technicians must ensure the liner seating surface is completely clean before fitting the shim. It is vital to measure the resulting protrusion against the manufacturer's specifications to confirm that the correct thickness has been applied to maintain proper combustion sealing.Troubleshooting and selection
Regular inspection of the cylinder assembly during maintenance intervals can help identify if shims require replacement due to wear or improper seating, ensuring the engine remains reliable under high-load conditions.Technical Specifications

FAQ
What is the purpose of a piston and liner shim?
A shim is used to adjust the liner protrusion to a specific target range, ensuring the cylinder head gasket receives even clamping pressure to prevent leaks.
Can I use this shim for any diesel engine?
No, this specific 0.15 mm shim is designed for TD70 engines with a 126.60 mm outside diameter and 120.10 mm inside diameter.
Why is measuring protrusion important?
Accurate measurement ensures that the chosen shim thickness correctly positions the liner, which is vital for maintaining a proper seal between the head and the block.
What happens if the wrong thickness shim is used?
Using an incorrect thickness can lead to improper liner protrusion, which may cause head gasket failure or loss of compression in heavy-duty engines.
