A0021301115 INTOURO OM 457 HLA Cylinder Head

What does a cylinder head do?

This cylinder head is the critical cast component that seals the top of the air brake compressor cylinder block while providing the necessary seats for the inlet and discharge valves. It plays a vital role in maintaining pneumatic pressure by containing compressed air and routing it through the discharge port, while also assisting in heat dissipation from the compression cycle.

Compatible vehicles and engines

Specifically designed for Mercedes-Benz INTOURO trucks, this part is compatible with various configurations including the INTOURO ME, INTOURO, INTOURO E, and INTOURO M models featuring the OM 457 HLA engine. By replacing only the cylinder head, workshop technicians can effectively rebuild the existing compressor unit, ensuring continued air system reliability without the cost of a complete assembly replacement.

Installation and maintenance

When performing installation, ensure that all valve seats are clean and that the mounting surfaces are free from any debris to prevent air leaks. Proper torque application during assembly is essential to maintain a secure seal against the cylinder block under high-pressure operating conditions. Regular inspection of the head surface and valve seats can help prevent premature wear and maintain optimal air pressure delivery.

Troubleshooting guidance

Consult your authorized distributor to verify exact fitment for your specific engine configuration.
