Description
What does a compressor cylinder head do?
A 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. This part is essential for workshop technicians performing in-place rebuilds of air brake compressors, serving as a more efficient alternative to replacing the entire unit.System compatibility and function
This component is compatible with WABCO systems. It functions by providing the necessary seats for inlet and discharge valves, internal air passages, and cooling cavities. These features directly govern both the compressor's air output and its operational temperature during heavy-duty cycles.Technical selection and installation
When selecting a replacement, technicians should verify the specific architecture of the existing unit, such as whether it is a single-cylinder or twin-cylinder design. It is also important to check if the head requires specific cooling configurations or includes an unloader port to receive governor signals correctly.Maintenance and selection guidance
Consult your authorized distributor to ensure the selected cylinder head meets the specific requirements of the compressor assembly to maintain system integrity and performance.OE cross-reference
12 05 11 (Compressor Cylinder Head) is the equivalent of the WABCO OE number. This part directly replaces WABCO OE number 9115140010S1.Other OEMs

FAQ
What is the function of a compressor cylinder head?
It seals the compression chamber from above and houses the inlet and discharge valve seats, directly impacting air output and temperature regulation.
Can this part be used to rebuild an existing compressor?
Yes, this component allows a workshop technician to rebuild a compressor in place rather than replacing the entire unit.
How do I ensure correct fitment for my WABCO system?
Selection should be based on the specific compressor architecture and reference numbers to ensure compatibility with your current air brake system.
What types of cylinder heads are available?
Depending on the design, heads may be single-cylinder, twin-cylinder, air-cooled with external fins, or water-cooled with jacket channels.
What are the OE reference numbers of this part?
12 05 11 directly replaces WABCO OE number 9115140010S1.
