22 02 50 Cylinder Head for Air Brake Compressors

What does a compressor cylinder head do?

This cylinder head is a critical cast component designed to seal the top of an air brake compressor's cylinder block while housing the valve seats for inlet and discharge. It plays a vital role in maintaining air pressure within the pneumatic system and managing heat dissipation during the compression cycle.

Compatible vehicles and engines

This part is compatible with heavy commercial vehicles including Freightliner Columbia and Coronado models, Peterbilt 379 and 389 series, and Kenworth T600 and W900 trucks. It is specifically designed for use with Caterpillar C15, C13, C11, and C7 engines across various brands like International, Sterling, and Western Star. Check the compatibility list.

Installation and maintenance

When performing installation, technicians must ensure the sealing face is perfectly flat to prevent gasket leaks. Proper torque must be applied according to the engine manufacturer's service manual to maintain structural integrity under high pressure. This component is essential for rebuilding compressors in place rather than replacing the entire unit.

Troubleshooting guidance

Maintaining correct compression levels requires inspecting the discharge port and valve seats for any signs of erosion or debris.
