3090385 Crankshaft Flange for Volvo F12 TD122

What does a crankshaft flange do?

The compressor crankshaft flange acts as the essential 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 compressor housing and the crankshaft. This component ensures that the drive force reaches the crankshaft in a perfectly centered manner.

Compatible vehicles and engines

This specific part is engineered for compatibility with Volvo F12 trucks equipped with TD122 engines, including variants such as F 12/370, F 12/360, F 12/400, F 12/410, F 12/320, and F 12/330. It is built to withstand the rigorous demands of heavy commercial vehicle applications where precision in air system pressure maintenance is required.

Installation and maintenance

For proper installation, technicians should verify that the pilot diameter, bolt hole circle, and seal seat size match the existing component to prevent leakage or excessive vibration. Maintaining correct alignment during assembly is crucial for preventing premature wear on the compressor seals and bearings.

Troubleshooting and selection

When replacing this component, ensure all mounting surfaces are clean and free of debris to maintain a high-strength seal. This part is an essential component for maintaining optimal air pressure within the braking system of heavy commercial vehicles.
