Description

What does a compressor cylinder head do?

This compressor cylinder head acts as the cast service component that sits on top of an air brake compressor's cylinder block, sealing the compression chamber from above. It is a vital component for workshop technicians who need to rebuild a compressor in place rather than replacing the entire unit. By providing the necessary seats for inlet and discharge valves, this part directly governs both air output and running temperatures.

Compatibility and application

This component is compatible with WABCO systems. It is designed to withstand heavy-duty operating conditions within the pneumatic braking system of commercial vehicles.

Installation and maintenance guidance

When performing maintenance, technicians should ensure the cylinder head is inspected for any cracks or uneven surfaces before installation. Proper seating of the gasket and correct torque application are essential to prevent air leaks and maintain consistent compression levels within the braking circuit.

Maintenance benefits

Replacing only the cylinder head can be a cost-effective solution during a compressor overhaul, provided the internal air passages and cooling cavities are free from obstructions or excessive wear.

OE cross-reference

11 20 10 (Compressor Cylinder Head) is the equivalent of the WABCO OE number. This part directly replaces WABCO OE number 4111518012.
