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. It is a vital component for workshop technicians performing in-place rebuilds of air brake compressors, often referred to as a compressor cover or top cover.System compatibility and application
This part is designed to work within heavy commercial vehicle air systems, providing the necessary internal air passages and valve seats. It is compatible with Knorr-Bremse systems. By replacing only the head, maintenance teams can restore compressor performance without replacing the entire unit.Installation and maintenance
When performing installation, technicians should verify the port alignment and ensure the sealing surfaces are free of debris. Proper mounting ensures that the internal air passages and cooling cavities function correctly to maintain stable operating temperatures under high load.Selection guidance
Consult your authorized distributor to ensure this component matches the specific architecture of the existing compressor unit.OE cross-reference

FAQ
What is the function of a compressor cylinder head?
The cylinder head seals the compression chamber from above and houses the inlet and discharge valve seats, directly governing air output and temperature.
Can this part be used to rebuild an existing compressor?
Yes, this component allows workshop technicians to rebuild a compressor in place rather than replacing the entire unit.
How do I ensure compatibility with my compressor?
Selection should always be based on the specific architecture and reference number of the existing compressor unit.
What are common symptoms of a faulty cylinder head?
Issues may include unstable air output or abnormal operating temperatures due to improper sealing or passage obstruction.
What are the OE reference numbers of this part?
12 14 50 directly replaces Knorr-Bremse OE number LK3927S1.
