002 130 11 15 Cylinder Head for Mercedes-Benz OM 457 HLA

What does a cylinder head do?

This compressor cylinder head is the precision-engineered component that seals the top of the air brake compressor cylinder block. It provides the essential seating for inlet and discharge valves, ensuring that compressed air is routed through the discharge port without leakage. Built with high-strength components, this part is designed to withstand the intense thermal and pressure cycles inherent in heavy-duty pneumatic systems.

Vehicle and engine compatibility

This specific cylinder head is compatible with Mercedes-Benz vehicles equipped with OM 457 HLA engines. It is manufactured to meet the rigorous requirements of heavy commercial vehicle braking systems, ensuring seamless integration with existing compressor architectures. The component is designed to facilitate efficient air compression for truck and bus applications.

Installation and maintenance

When replacing this component, technicians should verify that the bolt hole pattern and port dimensions match the original specifications exactly. Because even minor deviations in flatness can lead to gasket leaks, it is essential to inspect the sealing surface during installation. Proper torque application according to service manuals ensures long-term reliability of the pneumatic circuit.

Troubleshooting and replacement

Monitoring for signs of air leakage around the discharge port or excessive heat buildup can help identify when a rebuild is necessary. Utilizing high-quality replacement parts allows for efficient in-place rebuilding of the compressor rather than a full unit replacement.

OE cross-reference

11 25 50 (Compressor Cylinder Head) is the equivalent of the Mercedes-Benz OE number. This part directly replaces Mercedes-Benz OE number 0021301115.
