447 130 00 45 Compressor Crankshaft Flange for Mercedes-Benz

What does a compressor crankshaft flange do?

The compressor crankshaft flange serves as the critical connecting element that links the air brake compressor's crankshaft to the engine drive. It carries the bearing and seal seat on the drive side of the crankshaft, performing vital centering, sealing, and load transfer duties between the housing and the crankshaft. This component ensures that the drive mechanism, whether gear, belt-pulley, or coupling, reaches the crankshaft in a perfectly centered position.

Compatible vehicles and engines

This specific flange is designed for use in heavy commercial vehicle applications, specifically for Mercedes-Benz CONECTO (O 345) series including H, M, UE, and CONECTO C variants. It is engineered to work seamlessly with OM 447 HLA engines to maintain optimal pneumatic system pressure and stability.

Installation and maintenance

For workshop technicians, proper installation is vital to prevent leakage or excessive vibration. When replacing this part, ensure that the pilot diameter, bolt hole circle, and seal seat dimensions match the existing unit exactly. Even a slight mismatch in these dimensions can lead to rapid component wear or system failure.

Troubleshooting and selection
