Description
What does a compressor cylinder head do?
This compressor cylinder head acts as the essential service component that sits atop the air brake compressor's cylinder block, sealing the compression chamber from above. By providing a secure seal and housing the internal air passages, this part allows workshop technicians to rebuild an existing compressor rather than replacing the entire unit. It is often referred to in service manuals as a compressor cover or cylinder cover.Compatibility and application
This component is designed to be compatible with WABCO systems. Its architecture is crucial for maintaining correct air output and managing running temperatures during operation. Whether used in single-cylinder or twin-cylinder configurations, it ensures the integrity of the compression chamber under heavy-duty loads.Installation and maintenance
During installation, technicians should inspect the seating areas for the inlet and discharge valves to ensure a perfect seal. Proper maintenance of the cylinder head and its associated valve plates is vital for preventing pressure drops within the pneumatic system. Consult your authorized distributor for fitment guidance.Troubleshooting and selection
A worn cylinder head can lead to decreased air pressure or overheating. Regularly checking the external surfaces and cooling cavities helps prevent premature failure in heavy commercial vehicle applications.OE cross-reference
12 05 11 (Compressor Cylinder Head) is the equivalent of the WABCO OE number. This part directly replaces WABCO OE number 9115140020S1.Other OEMs
