3094836 Compatible F12 TD120 Compressor Crankshaft Flange

What does a crankshaft flange do?

The compressor crankshaft flange acts as a critical connecting element that links the air brake compressor's crankshaft to the engine drive. By carrying the bearing and seal seat on the drive side, this component jointly undertakes the centering, sealing, and load transfer duties between the compressor housing and the crankshaft. Proper alignment is essential to prevent vibration and leakage within the pneumatic system.

Vehicle and engine compatibility

This specific component is compatible with Volvo F12 trucks equipped with TD120 engines. It is engineered to meet the rigorous demands of heavy commercial vehicle service, ensuring that the drive force—whether via gear, belt-pulley, or coupling—is transmitted to the crankshaft with high precision.

Installation and maintenance guidance

When performing maintenance or repairs, technicians should verify the pilot diameter, bolt hole circle, and seal seat size against the existing part. Ensuring these dimensions match is vital to prevent premature leakage or excessive vibration. Check the compatibility list to confirm fitment for your specific engine configuration.

Troubleshooting and replacement

If you observe unusual vibrations or air leakage near the compressor drive side, it may indicate that this flange requires replacement to maintain system integrity.
