911 504 800 2 Compressor Cylinder Head for WABCO Systems

What does a compressor cylinder head do?

This compressor cylinder head acts as the cast service component that sits on top of an air brake compressor's cylinder block, sealing the compression chamber from above. It is a vital part for workshop technicians looking to rebuild a compressor in place rather than replacing the entire unit. Inside the head, the seats for the inlet and discharge valves, internal air passages, and cooling cavities are located, directly governing both the air output and the running temperature of the unit.

Compatibility and application

This component is designed to be used in heavy commercial vehicle applications where reliable air pressure is essential. It is compatible with WABCO systems and other professional-grade air brake setups. Maintenance of this part is crucial to prevent pressure loss within the pneumatic braking circuit.

Maintenance and installation

When performing a rebuild, technicians should inspect the cylinder block surface and ensure all valve seats are correctly seated. This part ensures the compressor maintains stable performance under sustained high loads by managing internal air passages and thermal distribution.

Selection guidance

Consult your authorized distributor to ensure correct fitment for your specific compressor architecture.
