Description

What does a piston & liner shim do?

This piston & liner shim is a critical adjustment component used to set the correct liner protrusion within a heavy-duty diesel engine. By placing this shim between the cylinder liner and the engine block, technicians can achieve the exact clearance required for optimal head gasket clamping pressure. This precision is vital for maintaining efficient combustion and preventing leaks during engine overhauls.

Compatibility and application

This specific part is designed for Mercedes-Benz engines, providing a reliable fitment for heavy commercial vehicle service requirements. The component features a 153.50 mm outside diameter and a 146.90 mm inside diameter, specifically tailored for applications requiring a 0.50 mm thickness adjustment to ensure long-term structural integrity under high pressure.

Installation and maintenance

When performing engine maintenance or replacing liners, technicians should measure the current protrusion to select the correct shim thickness from the available range. Proper installation of this component prevents uneven sealing and protects the cylinder head gasket from premature failure. Consult your authorized distributor to ensure exact fitment.

Engine sealing importance

Maintaining correct liner seating is essential for thermal stability and compression within the combustion chamber.
