Description

What does a cylinder head do?

The cylinder head is a critical cast service component that sits on top of an air brake compressor's cylinder block, sealing the compression chamber from above. By replacing only the head, workshop technicians can rebuild a compressor in place rather than replacing the entire unit. This component directly governs both the compressor's air output and its running temperature through internal air passages and valve seats.

Compatibility and fitment

This part is compatible with Knorr-Bremse systems and is designed to withstand heavy-duty operating conditions. It serves as a vital replacement part for maintaining pneumatic system integrity in heavy commercial vehicles.

Installation and maintenance

When performing maintenance, technicians should verify that the head matches the specific compressor architecture, whether it is an air-cooled or water-cooled design. Ensure all valve seats and cooling cavities are inspected during installation to maintain optimal pressure levels.

Selection guidance

Consult your authorized distributor for specific fitment guidance regarding unloader ports or valve plate configurations.

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 AC63ZBS1.
