Description

What does a cylinder head do?

This cylinder head functions as the primary seal for the air brake compressor cylinder block, ensuring the compression chamber remains airtight. By sealing the chamber from above, it allows workshop technicians to perform efficient rebuilds of existing units rather than requiring a full compressor replacement. This component directly influences both the air output and the thermal management of the compression cycle.

Compatibility and application

This part is compatible with Knorr-Bremse systems and is used in heavy commercial vehicle air brake systems. It serves as a high-strength replacement to restore optimal pressure performance in pneumatic braking systems.

Installation and maintenance

When performing maintenance, technicians should verify the compressor architecture to ensure correct fitment. Proper installation ensures that valve seats and internal air passages function correctly, maintaining stable temperatures under high load. Consult your authorized distributor for specific application details.

Troubleshooting and inspection

Regular inspection of the cylinder head can prevent air leaks and pressure drops in the braking system.

OE cross-reference

15 05 10 (Compressor Cylinder Head) is the equivalent of the Knorr-Bremse OE number. This part directly replaces Knorr-Bremse OE number AC63ZBGS1.

FAQ

What is the function of a compressor cylinder head?
The cylinder head sits on top of the compressor block to seal the compression chamber, housing the inlet and discharge valve seats and internal air passages.
Can this part be used for system rebuilding?
Yes, this component allows workshop technicians to rebuild an air brake compressor in place, extending the service life of the unit without replacing the entire assembly.
What symptoms indicate a faulty cylinder head?
Common signs include air leaks from the top of the compressor, loss of air pressure, or abnormal running temperatures during operation.
How do I ensure compatibility with my compressor?
Selection should always be based on the specific compressor architecture and its own reference number to ensure correct sealing and valve fitment.
What are the OE reference numbers of this part?
15 05 10 directly replaces Knorr-Bremse OE number AC63ZBGS1.
