25 28 11 Compressor Cylinder Head for Cummins Engines

What does a compressor cylinder head do?

This compressor cylinder head serves as the critical sealing component that closes the top of an air brake compressor's cylinder block. It houses the seats for the inlet and discharge valves, ensuring that compressed air is routed correctly through the discharge port while managing compression heat. Built with heavy-duty grade materials, it is essential for maintaining consistent pneumatic pressure within the braking system.

Vehicle and engine compatibility

This specific cylinder head is compatible with several heavy commercial vehicle models, including KamAZ 6520, Iveco Bus Metro, and Ford Trucks Cargo. It is also fitted to Dongfeng Tianjin, Yutong ZK6125, and Volkswagen Constellation vehicles utilizing Cummins ISLe or ISBe engines. Such components are vital for maintaining the integrity of air brake compressors in various heavy-duty applications.

Installation and maintenance

Technicians should inspect the cylinder head during routine pneumatic system maintenance to prevent air leaks or pressure drops. When replacing this part, ensure the valve plate and gaskets are in optimal condition to maintain an airtight seal. Proper installation ensures the compressor operates within its intended thermal and pressure parameters throughout its service life.
