51541146070 Cylinder Head Compatible with MAN ND

What does a cylinder head do?

This cylinder head is the essential cast component that seals the top of the air brake compressor cylinder block. It provides the necessary housing for the inlet and discharge valve seats, ensuring that compressed air is routed through the discharge port without leakage. Built with high-strength components, it also plays a vital role in dissipating compression heat from the main body.

Compatibility with MAN ND models

This specific part is designed for use in MAN ND compressors, including the 313 and 363 variants. It is an ideal solution for workshop technicians looking to rebuild compressor units in place rather than replacing the entire assembly, ensuring long-term reliability for heavy commercial vehicle fleets.

Installation and maintenance guidance

When performing installation, technicians should verify that all valve seats are perfectly aligned and that discharge ports are free of debris. Regular inspection of the cylinder head surface is recommended to prevent air leaks and ensure consistent pressure delivery within the pneumatic system.

Ensuring system reliability

Maintaining proper seating for the valves is critical for preventing pressure drops in the braking system. Using high-grade replacement components helps maintain the structural integrity of the compressor under sustained high loads.

OE cross-reference

12 02 20 (Compressor Cylinder Head) is the equivalent of the MAN OE number. This part directly replaces MAN OE number 51541146070.
