001 130 57 15 Mercedes-Benz CITARO Cylinder Head

What does a compressor cylinder head do?

This compressor cylinder head serves as the essential cast component that seals the top of the air brake compressor cylinder block. It provides the necessary seating for both inlet and discharge valves, ensuring the compression chamber remains airtight under high pressure. By managing internal air passages and heat dissipation, this part is critical for maintaining stable air output in heavy commercial vehicle braking systems.

Compatible Mercedes-Benz CITARO models

This specific component is compatible with Mercedes-Benz CITARO (O 530) buses, including variants such as the Citaro N, Citaro GN3, Citaro MUE, Citaro LÜ, and Citaro G. It is specifically designed for use with OM 457 HLA engines to ensure exact fitment and performance within the pneumatic system.

Installation and maintenance guidance

When performing a rebuild, technicians should verify the bolt hole pattern and port dimensions against the existing unit to ensure a perfect match. Proper installation requires following manufacturer torque specifications to prevent gasket leaks at the sealing face. Maintaining clean mounting surfaces is vital for long-term durability in high-pressure environments.

Component reliability and service

Using high-strength components during compressor overhauls helps prevent premature air leaks and ensures consistent pressure delivery to the vehicle's pneumatic circuits.
