51541146002 MAN Compatible Compressor Cylinder Head

What does a compressor cylinder head do?

This compressor cylinder head is a cast service component that sits on top of an air brake compressor's cylinder block and seals the compression chamber from above. It is engineered to allow workshop technicians to rebuild a compressor in place rather than replacing the whole unit, serving as a vital part for maintaining pneumatic system integrity.

Vehicle compatibility and function

This specific component is compatible with MAN heavy commercial vehicles. It functions as the primary seal for the compression chamber, housing the seats for the inlet and discharge valves, internal air passages, and cooling cavities. These elements directly govern both the compressor's air output and its running temperature during heavy-duty operation.

Installation and maintenance

When performing maintenance or repairs, technicians should inspect the cylinder head for signs of wear around the valve seats or cooling passages. Proper installation is critical to ensure a complete seal within the compression chamber and to prevent pressure loss within the braking system.

Selection guidance

Consult your authorized distributor to ensure this part matches your specific compressor architecture, as selection depends on whether your unit requires single-cylinder or twin-cylinder configurations.
