11 30 31 Compatible Cylinder Head for Mercedes-Benz

What does a compressor cylinder head do?

This compressor cylinder head serves as the critical cast component that seals the top of the air brake compressor cylinder block. It is engineered to house the inlet and discharge valve seats, managing internal air passages to ensure efficient compression. By maintaining a high-pressure seal within the chamber, this part plays a vital role in the pneumatic braking system's overall performance and thermal management.

Compatible vehicles and engines

This specific component is designed for use in Mercedes-Benz CITARO (O 530) variants including GN3, G, LÜ, MUE, and N, as well as Setra Series 400 models like MultiClass S 415 and 416. It is also compatible with Mercedes-Benz CONECTO (O 345) and CAPACITY units, specifically supporting OM 457 LA, OM 457 HLA, and OM 447 HLA engine configurations. These parts are suitable for WABCO systems found in heavy commercial vehicles.

Installation and maintenance

For workshop technicians performing compressor overhauls, this cylinder head allows for precise rebuilding of the unit in place. When replacing the head, it is important to inspect the valve seats and ensure all seals are correctly seated to prevent air leaks. Maintaining proper torque during installation is crucial for consistent air output and long-term durability under heavy load.

Troubleshooting and selection

Regular inspection of the cylinder head can prevent system failures by identifying early signs of erosion or heat stress. Selecting a high-strength component ensures that the compressor maintains its required pressure levels throughout its service life.
