51541146066 Cylinder Head for MAN ND Trucks

What does a compressor cylinder head do?

This compressor cylinder head serves as the critical cast component that seals the top of the air brake compressor cylinder block. It provides the necessary housing for inlet and discharge valve seats, ensuring that compressed air is routed correctly through the discharge port while managing compression heat during operation.

Compatible MAN ND vehicles

This specific part is compatible with MAN ND vehicles, including the 313 and 363 variants. It is engineered to meet OE dimensions, allowing workshop technicians to rebuild existing compressors in place rather than replacing the entire unit, which optimizes maintenance efficiency for heavy commercial vehicle fleets.

Installation and maintenance

When installing this component, technicians should verify the integrity of the valve seats and ensure all sealing surfaces are clean to prevent air leakage. Proper mounting ensures the cylinder head maintains stable pressure levels within the pneumatic system during sustained heavy-duty operation.

Selection guidance

Consult your authorized distributor to ensure this component matches your specific compressor architecture and port configuration.
