Description

What does a cylinder head do?

A compressor cylinder head is the cast service component that sits on top of an air brake compressor's cylinder block and seals the compression chamber from above.

Application and compatibility

This component is essential for workshop technicians looking to rebuild compressors in place rather than replacing the entire unit. It serves as the interface between the compression chamber and the external valves, directly governing both the air output and the running temperature of the compressor assembly.

Maintenance and replacement

Designed to meet high-performance standards, this part is compatible with Knorr-Bremse systems. It is built using heavy-duty grade materials to withstand the constant thermal cycling and pressure variations inherent in heavy commercial vehicle air brake systems.

Selection guidance

When selecting a replacement, ensure the part matches the specific compressor architecture, such as single-cylinder or twin-cylinder configurations. Consult your authorized distributor to confirm exact fitment for your specific compressor model.

OE cross-reference

16 11 50 (Compressor Cylinder Head) is the equivalent of the Knorr-Bremse OE number. This part directly replaces Knorr-Bremse OE number LK1539S2.

FAQ

What is the function of a compressor cylinder head?
It sits atop the cylinder block to seal the compression chamber and houses the inlet and discharge valve seats, regulating air output.
Can this part be used to rebuild an existing compressor?
Yes, this component allows workshop technicians to rebuild a compressor in place, avoiding the need for a complete unit replacement.
How do I ensure this head fits my compressor?
Selection should be based on the specific architecture of your compressor, such as whether it is air-cooled or water-cooled.
What are common symptoms of a faulty cylinder head?
Issues may include abnormal running temperatures or reduced air output due to improper sealing of the compression chamber.
What are the OE reference numbers of this part?
16 11 50 directly replaces Knorr-Bremse OE number LK1539S2.
