A0021301115 CITARO (O 530) OM 457 HLA Compressor Head

This compressor cylinder head is a precision-engineered component designed to seal the top of the air brake compressor cylinder block. It functions by housing the valve seats and managing the internal air passages to ensure consistent compression and efficient heat dissipation. Using high-strength components, this part allows for a cost-effective rebuild of the compressor system without requiring a full unit replacement.

This specific cylinder head is compatible with Mercedes-Benz CITARO (O 530) models, including the GN3, N, MUE, G, and LÜ variants fitted with OM 457 HLA engines. It is engineered to meet the exact specifications required for these heavy commercial vehicle applications, ensuring seamless integration within the pneumatic system.

When performing installation, technicians should carefully inspect the sealing face for flatness and ensure all bolt hole patterns match the original specifications. It is essential to follow the manufacturer's torque requirements during assembly to prevent gasket leaks or pressure loss. Maintaining clean mounting surfaces is vital for a long-lasting seal in high-pressure environments.
