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. By providing seats for the inlet and discharge valves, it directly governs both the air output and the running temperature of the unit. Using this component allows a workshop technician to rebuild a compressor in place, extending the service life of the assembly.

Vehicle and system compatibility

This part is compatible with Knorr-Bremse systems and is utilized in various heavy commercial vehicle applications. Due to differences in compressor architecture, selection must be based on the specific compressor reference to ensure correct fitment for the engine and braking system.

Installation and maintenance guidance

When performing maintenance, technicians should inspect the valve seats and internal air passages for signs of wear or carbon buildup. Ensuring a clean mating surface between the head and the cylinder block is vital for maintaining pressure integrity and preventing air leaks during operation.

Troubleshooting and selection

If air output decreases or temperature rises unexpectedly, inspecting this component is a recommended troubleshooting step to restore full system performance.

OE cross-reference

24 02 50 (Compressor Cylinder Head) is the equivalent of the Knorr-Bremse OE number. This part directly replaces Knorr-Bremse OE number LK4959S1.

FAQ

What is the function of a compressor cylinder head?
It seals the compression chamber from above and houses the inlet/discharge valve seats, directly controlling air output and running temperature.
Can I use this head to rebuild an existing compressor?
Yes, this component allows a workshop technician to rebuild a compressor in place rather than replacing the entire unit.
How do I ensure correct compatibility?
Selection should always be based on the specific compressor's reference number to match the correct architecture and engine requirements.
What are common symptoms of a faulty cylinder head?
Reduced air output or abnormal operating temperatures are common indicators that the head or its internal valves require inspection.
What are the OE reference numbers of this part?
24 02 50 directly replaces Knorr-Bremse OE number LK4959S1.
