Description
What does a compressor cylinder head do?
This compressor cylinder head serves as the critical cast component positioned atop the air brake compressor cylinder block. By sealing the compression chamber from above, it allows workshop technicians to rebuild a compressor in place rather than replacing the entire unit. It is often referred to in the field as a compressor cover or cylinder cover.Compatibility and system function
This component is compatible with WABCO systems and is essential for maintaining the integrity of the pneumatic circuit. It governs both the air output and the running temperature of the compressor through internal air passages and cooling cavities.Installation and maintenance guidance
When performing maintenance, technicians should inspect the seats for inlet and discharge valves to ensure a proper seal. Proper installation ensures that the compressor maintains consistent pressure levels under heavy load conditions. Check the compatibility list to ensure correct fitment.Selection and architecture
Selecting the correct head is vital, as designs vary between single-cylinder, twin-cylinder, air-cooled, and water-cooled architectures.OE cross-reference
11 03 11 (Compressor Cylinder Head) is the equivalent of the WABCO OE number. This part directly replaces WABCO OE number 4129056544.Other OEMs
