A0011305715 Mercedes-Benz CITARO Cylinder Head

What does a compressor cylinder head do?

This cylinder head is a critical service component designed to seal the top of an air brake compressor's cylinder block. It provides the necessary housing for inlet and discharge valve seats, ensuring that compressed air is directed accurately through the discharge port while maintaining pressure within the chamber. Built from high-strength components, this part allows for efficient heat dissipation during the compression cycle.

Vehicle and engine compatibility

This specific cylinder head is compatible with Mercedes-Benz CITARO (O 530) vehicles, including the N, GN3, MUE, LÜ, and G variants, specifically when fitted with OM 457 HLA engines. It serves as a precise replacement for original equipment parts, facilitating the professional rebuilding of compressors in heavy commercial vehicle service environments.

Installation and maintenance guidance

When performing installation, technicians should verify that the bolt hole pattern and port dimensions match the existing unit exactly to prevent leaks. Because even minimal deviations in the sealing face can cause pressure loss, it is essential to follow the manufacturer's torque specifications during assembly. Consult your authorized distributor for fitment verification.

Troubleshooting and selection

Regular inspection of the cylinder head and valve seats is recommended to prevent air leaks or temperature irregularities within the pneumatic system.
