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.

Compatibility and application

This component is vital for the performance of the air brake system, as it contains the seats for the inlet and discharge valves, internal air passages, and cooling cavities. By replacing this part, a workshop technician can rebuild a compressor in place rather than replacing the entire unit. This specific head is designed to maintain high pressure and stable operating temperatures during heavy-duty use.

Installation and maintenance

This part is compatible with Knorr-Bremse systems. It serves as a critical replacement component for maintaining the integrity of the pneumatic system within heavy commercial vehicle air brake compressors.

Troubleshooting and selection

When performing maintenance, technicians should inspect the valve seats and air passages to ensure no obstructions exist. Proper installation ensures the compressor maintains correct discharge pressure and prevents leaks within the compression chamber.

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 LK1525S2.
