Description
What does a piston & liner shim do?
This piston and liner shim is a critical adjustment component used to bring the cylinder liner protrusion into the exact target range during engine overhauls. By providing the necessary thickness between the liner and the block seating surface, it ensures that the cylinder head gasket receives the correct clamping pressure, preventing gas leaks and ensuring long-term engine sealing.Technical specifications for TD70
Designed specifically for TD70 engine applications, this shim features an outside diameter of 126.60 mm and an inside diameter of 120.10 mm with a precise thickness of 0.40 mm. These dimensions are vital for maintaining the structural integrity of the combustion chamber under high-pressure operating conditions.Installation and maintenance guidance
When performing engine maintenance or replacing liners, technicians should measure the current protrusion to select the correct shim thickness from a graduated series. Proper installation on a clean, flat surface is essential to avoid uneven load distribution on the head gasket.Importance of correct thickness
Using high-strength components like this shim helps prevent repeat gasket failures and ensures the longevity of the engine block assembly in heavy-duty service environments.Technical Specifications

FAQ
What is the purpose of a piston & liner shim?
It is used to adjust the liner protrusion height to ensure the cylinder head gasket is clamped with the correct force, preventing leaks.
What are the dimensions of this specific shim?
This shim has an outside diameter of 126.60 mm, an inside diameter of 120.10 mm, and a thickness of 0.40 mm.
Can I use any thickness for liner shims?
No, you must measure the protrusion accurately and select a specific thickness, such as this 0.40 mm version, to match engine requirements.
Why is precise thickness important for TD70 engines?
Correct thickness ensures balanced clamping load on the gasket; incorrect shims can lead to gas leaks or premature component failure.
