Description
What does a compressor cylinder head do?
This compressor cylinder head is the cast service part that closes off the top of an air brake compressor's cylinder block and carries the seats for the inlet and discharge valves. It holds the piston's compressed air without leaking, routes it out through the discharge port, and carries away part of the compression heat from the body. It is designed for high-strength performance in demanding pneumatic environments.Compatible vehicles and engines
This component is compatible with Knorr-Bremse systems and is used on various heavy commercial vehicles such as Dongfeng Tianjin, Yutong ZK6118, KamAZ 5308, KamAZ 4308, Dongfeng Captain, Ford Trucks Cargo, Dongfeng Duolika, KamAZ 65115, Liaz 5292, Nefaz 5299, Zhongtong LCK6118, Paz 3204, Paz 3237, and Volkswagen Constellation models featuring ISBe engines. It is also compatible with Cummins LF45 and LF55 engines.Installation and maintenance
Technicians should inspect the cylinder head for signs of thermal stress or surface scoring during routine maintenance. When installing this part, ensure that all valve seats are properly aligned and that the sealing surfaces are clean to prevent air leaks within the pneumatic circuit. Proper torque application is essential to maintain a secure connection to the cylinder block.Troubleshooting and selection
Maintaining a high-quality cylinder head ensures reliable air pressure delivery for the vehicle's braking system. Checking for leaks around the discharge port can help identify early signs of wear in the compression chamber.OE cross-reference
