Description

What does a compressor cylinder head do?

This compressor cylinder head acts as the cast service component positioned on top of the air brake compressor cylinder block to seal the compression chamber. It is an essential part for workshop technicians looking to rebuild a compressor in place rather than replacing the entire unit. This component directly governs both the air output and the running temperature of the system.

Compatibility and application

The cylinder head is designed to be compatible with WABCO systems. These components are vital for maintaining consistent pneumatic pressure in heavy commercial vehicle braking systems, ensuring reliable performance under demanding conditions.

Installation and maintenance

When performing maintenance, technicians should inspect the seats for the inlet and discharge valves to ensure proper sealing. Proper installation of this head is critical to prevent pressure drops or overheating during operation. Always consult your authorized distributor to ensure correct fitment for specific compressor architectures.

Troubleshooting and selection

Replacing only the cylinder head can be a cost-effective way to restore compression efficiency. Ensure that all seals and gaskets are replaced during the installation process to maintain system integrity.

OE cross-reference

25 08 11 (Compressor Cylinder Head) is the equivalent of the WABCO OE number. This part directly replaces WABCO OE number 9111545200S1.
