Description

What does a cylinder head do?

This cylinder head serves as the primary sealing component positioned atop the compressor cylinder block to secure the compression chamber. By acting as a cover, it manages internal air passages and houses the seats for both inlet and discharge valves. This part is essential for workshop technicians looking to rebuild a compressor in place, providing a cost-effective alternative to replacing the entire unit.

Compatibility and fitment

This component is compatible with Knorr-Bremse systems. It is engineered to withstand high-pressure environments within the air brake system of heavy commercial vehicles.

Installation and maintenance

When replacing this part, technicians should verify the compressor architecture, as heads may vary between single-cylinder or twin-cylinder configurations. Ensuring a precise fitment is vital for maintaining correct air output and preventing temperature fluctuations during operation. Check the compatibility list to confirm suitability.

Troubleshooting and selection

Proper maintenance of the cylinder head helps prevent air leaks and ensures stable compression levels. Regular inspection of the valve seats and cooling cavities within the head can prevent premature system failure.

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 AC63ZAGS1.

FAQ

What is the function of a cylinder head in an air brake compressor?
It seals the compression chamber from above and houses the inlet and discharge valve seats, directly governing air output and operating temperature.
Can this part be used to rebuild an existing compressor?
Yes, this component allows workshop technicians to rebuild an air brake compressor in place rather than replacing the complete unit.
How do I know if this cylinder head fits my compressor?
Selection should be based on the specific compressor architecture and its reference number to ensure compatibility with your system.
What are common signs of a faulty cylinder head?
Technicians should look for signs of air leaks, irregular compression levels, or abnormal running temperatures within the braking system.
What are the OE reference numbers of this part?
15 05 10 directly replaces Knorr-Bremse OE number AC63ZAGS1.
