Description

What does a compressor cylinder head do?

This compressor cylinder head acts as the cast service component that sits atop the air brake compressor 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. This component directly governs both the air output and the running temperature of the system.

Compatibility and fitment

This part is designed to be compatible with WABCO systems. It serves as a reliable replacement to restore pneumatic performance in heavy commercial vehicle braking systems. Due to different engine configurations, always verify fitment based on the specific compressor architecture.

Installation and maintenance

During installation, technicians should ensure that all mating surfaces are clean and inspect the valve seats within the head. Proper torque application on the mounting bolts is essential to maintain a proper seal and prevent pressure leaks within the compression chamber.

System performance and selection

Replacing only the cylinder head can be a cost-effective way to maintain fleet uptime while ensuring the integrity of the air brake system.

OE cross-reference

11 30 20 (Compressor Cylinder Head) is the equivalent of the WABCO OE number. This part directly replaces WABCO OE number 9125109252.
