A0021301115 Cylinder Head for Mercedes-Benz TRAVEGO

What does a compressor cylinder head do?

This cylinder head serves as the essential component that seals the top of the air brake compressor cylinder block, providing the necessary housing for inlet and discharge valve seats. It ensures that compressed air is contained and routed through the discharge port without leakage, while also assisting in managing compression heat during operation.

Compatible vehicles and engines

This specific part is designed for Mercedes-Benz TRAVEGO (O 580) models, including the O 580-15 RH and O 580-15 RHD variants, specifically when fitted with OM 457 hLA engines. It provides a direct replacement to restore compression efficiency in the pneumatic system.

Installation and maintenance

For correct installation, technicians should verify the cylinder count and port thread dimensions against the existing unit. It is recommended to inspect the valve seat bore diameter and bolt hole pattern to ensure a perfect match with the compressor block. Proper seating of the head is critical to prevent air leaks and maintain consistent pressure within the braking circuit.

System reliability

Maintaining the integrity of the cylinder head is vital for the long-term reliability of the vehicle's pneumatic system. Regular inspection of the sealing surfaces can prevent pressure drops and ensure stable air supply for heavy commercial vehicle braking operations.
