Description

What does a cylinder head do?

This 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. It plays a vital role in the pneumatic system by housing the seats for the inlet and discharge valves, as well as the internal air passages and cooling cavities. This component directly governs both the compressor's air output and its operational temperature.

System compatibility and rebuilding

This part is compatible with Knorr-Bremse systems and is designed to allow workshop technicians to rebuild a compressor in place rather than replacing the entire unit. By replacing only the cylinder head, service efficiency is increased during maintenance cycles.

Installation and maintenance

When performing installation, technicians should ensure that all valve seats and sealing surfaces are free of debris. Proper torque application on the mounting bolts is essential to maintain the integrity of the compression chamber and prevent air leaks under high pressure.

Selection guidance

Consult your authorized distributor to ensure this part matches your specific compressor architecture, as designs vary between single-cylinder and twin-cylinder configurations.

OE cross-reference

20 09 50 (Compressor Cylinder Head) is the equivalent of the Knorr-Bremse OE number. This part directly replaces Knorr-Bremse OE number LK1549S1.

FAQ

What is the function of a compressor cylinder head?
It seals the compression chamber from above and houses the inlet/discharge valve seats and internal air passages.
Can this part be used to rebuild an existing compressor?
Yes, it allows a workshop technician to rebuild a compressor in place instead of replacing the whole unit.
What should I check during installation?
Ensure all valve seats and sealing surfaces are clean and that mounting bolts are torqued to specification.
How do I know if this head fits my system?
Selection should be based on your compressor's specific reference number to ensure correct architecture compatibility.
What are the OE reference numbers of this part?
20 09 50 directly replaces Knorr-Bremse OE number LK1549S1.
