Description

What does a compressor cylinder head do?

This compressor cylinder head acts as the essential cast service component that sits on top of the air brake compressor's cylinder block. It seals the compression chamber from above, allowing workshop technicians to rebuild a compressor in place rather than replacing the entire unit. This component is vital for maintaining consistent air pressure within the braking system.

Compatibility and application

This part is compatible with BMC vehicles. It is designed to withstand high-pressure environments and provides the necessary seating for inlet and discharge valves, as well as internal air passages. By ensuring a proper seal, it directly governs both the compressor's air output and its overall running temperature during operation.

Installation and maintenance guidance

When performing maintenance or repairs, technicians should check the existing compressor's configuration, such as whether it requires an unloader port or specific cooling features. Replacing only the head can be a cost-effective solution for maintaining fleet uptime. Consult your authorized distributor.

OE cross-reference
