Description
What does a compressor cylinder head do?
This cylinder head is the essential cast component that seals the top of the air brake compressor cylinder block, providing a secure housing for the inlet and discharge valve seats. It plays a critical role in maintaining internal pressure while facilitating heat dissipation from the compression process. Built with high-strength components, it ensures long-term durability under heavy-duty service conditions.Compatible vehicles and engines
This part is designed for use in various heavy commercial vehicles, including KamAZ (65115, 5308, 4308, 6520), Ford Trucks Cargo models, and Iveco Bus Metro units. It is also compatible with Dongfeng (Tianjin, Captain, Duolika, Kinland), Yutong (ZK6118, ZK6125), Paz (3204, 3237), Liaz (5292), and Nefaz (5299) trucks equipped with Cummins ISBe or ISLe engines. Check the compatibility list.Installation and maintenance
When replacing this component, technicians should inspect the cylinder liner and valve plates to ensure optimal air-tight integration. Proper installation of the gasket and seal kits is vital to prevent pressure drops or external leaks. Regular inspection of the discharge port area is recommended during routine maintenance to prevent carbon buildup.Troubleshooting and replacement
If air leakage occurs from the compressor head or if compression pressure fails to meet operational requirements, this cylinder head serves as a reliable replacement to rebuild the unit in place rather than replacing the entire compressor assembly.OE cross-reference
