51541146086 Cylinder Head for MAN ND

What does a cylinder head do?

This cylinder head acts as the cast service part that closes off the top of the air brake compressor's cylinder block. It is designed to carry the seats for the inlet and discharge valves, ensuring that compressed air is held without leakage and routed correctly through the discharge port. By managing compression heat, this component is vital for maintaining consistent pneumatic pressure within the braking system.

Compatible vehicles and engines

This specific component is compatible with MAN ND series compressors, including the 313 and 363 variants. It is engineered to meet high-performance requirements for heavy commercial vehicle applications, providing a reliable solution for rebuilding compressor units in place rather than replacing the entire assembly.

Installation and maintenance

When replacing the cylinder head, technicians should inspect the valve seats and discharge ports to ensure no debris remains in the system. Proper installation ensures that the compressor maintains its required pressure output and prevents air leaks that could compromise braking performance. Consult your authorized distributor.

Troubleshooting and selection

Regular inspection of the cylinder head area can help identify early signs of wear or heat damage, preventing unexpected downtime in heavy-duty fleets.
