Description

What does a piston & liner shim do?

This piston and liner shim acts as a critical adjustment component within the engine block assembly. By being fitted between the cylinder liner and the seating surface, it allows technicians to achieve the exact liner protrusion required for proper clamping pressure. This precision is vital for maintaining the integrity of the cylinder head gasket seal under high combustion pressures.

Compatibility and application

Designed specifically for Mercedes-Benz engines, this component is essential during engine overhauls or liner replacements to ensure correct clearances. It is engineered with high-strength components to withstand the rigorous thermal and mechanical stresses found in heavy commercial vehicle engines.

Installation and maintenance

When performing maintenance, it is crucial to measure the current protrusion to select the correct thickness. This 0,10 mm shim helps maintain the required sealing interface. Always verify the outside diameter of 153,50 mm and inside diameter of 146,90 mm against the existing liner installation to ensure a perfect fit.

Troubleshooting and selection

Proper selection of shims prevents premature gasket failure and ensures long-term engine reliability. Consult your authorized distributor to ensure this component meets your specific engine requirements.
