26 04 50 Cylinder Head for Detroit Diesel 60 Series

What does a cylinder head do?

This compressor cylinder head is the critical cast component that seals the top of the air brake compressor cylinder block, housing the valve seats for both intake and discharge. It is engineered to maintain high-pressure air containment while managing the thermal loads generated during the compression cycle. By utilizing heavy-duty grade materials, this part ensures long-term durability under intense operating conditions.

Compatible vehicles and engines

This component is specifically designed to fit heavy commercial vehicles equipped with Detroit Diesel 60 Series engines. It is compatible with a wide range of truck models, including Freightliner (Cascadia, Columbia, Coronado, Century Class, Argosy, Classic XL, FLD120), Kenworth (T600, W900, T800), Peterbilt (379, 378), Western Star (4900, 4964), Sterling (AT9500, A9500, LT9500), and International (9400, 9200) units. Check the compatibility list.

Installation and maintenance

When performing a rebuild, technicians should verify the discharge port thread type and the bolt hole pattern against the existing unit to ensure a perfect seal. It is vital to inspect the sealing face for any flatness deviations that could lead to air leaks. Proper installation according to the vehicle manufacturer's torque specifications is required to prevent gasket failure.

Troubleshooting and selection

Regular inspection of the cylinder head can help prevent system pressure drops. If air leaks are detected at the compressor housing or if discharge pressure becomes inconsistent, replacing this component can restore full system integrity without replacing the entire compressor assembly.
