30 04 10 Cummins Compatible Compressor Cylinder Head

What does a compressor cylinder head do?

This compressor cylinder head serves as the critical cast component that seals the top of an air brake compressor cylinder block. It houses the valve seats and ensures airtight containment of compressed air while managing heat dissipation during the compression cycle.

Compatible vehicles and engines

This component is compatible with Cummins ISBe, ISLe, and ISDe engines. It is widely used in heavy commercial vehicles such as Dongfeng Duolika, Iveco Bus Metro, Volkswagen Constellation, KamAZ 5308, and Ford Trucks Cargo. This part is also fitted to Yutong, Liaz, and Zhongtong vehicles to maintain optimal pneumatic performance.

Maintenance and installation guidance

When performing maintenance or rebuilding a compressor, technicians should inspect the cylinder head for surface irregularities or leaks around the valve seats. Proper installation ensures that the discharge port functions correctly under high-pressure loads typical of heavy-duty duty cycles.

System reliability

Maintaining the integrity of the cylinder head is essential for stable air pressure in the braking system. Using high-strength components helps prevent premature failure in demanding transport environments.
