22 03 20 Detroit Diesel Compatible Cylinder Head

What does a compressor cylinder head do?

This compressor cylinder head serves as the critical component that closes the top of the air brake compressor cylinder block. It carries the seats for the inlet and discharge valves, ensuring the piston's compressed air is contained and routed through the discharge port without leakage. By managing pressure and heat dissipation, this part is essential for the sustained performance of pneumatic braking systems.

Vehicle and engine compatibility

This component is engineered for compatibility with Detroit Diesel Series 60 engines found in a wide range of heavy commercial vehicles. It is fitted to models from Freightliner (including Cascadia and Columbia), Kenworth (T800, W900, T600), Peterbilt (378, 379), Western Star (4900, 4964), International (9400, 9200), and Sterling (A9500, LT9500, AT9500). These parts are also used in various heavy-duty truck applications to maintain optimal air pressure.

Installation and maintenance

Technicians should verify that the bolt hole pattern and port dimensions match the existing unit before installation. Because even minor deviations in the sealing face can lead to gasket leaks, ensuring a clean mating surface is vital. For optimal service life, always follow the manufacturer's torque specifications when securing the head to the cylinder block.

Selection guidance

Consult your authorized distributor to ensure correct fitment for your specific engine configuration.
