3097150 Crankshaft Flange compatible with Volvo FH12

What does a crankshaft flange do?

The compressor crankshaft flange serves as a vital 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 essential centering, sealing, and load transfer duties between the compressor housing and the crankshaft. Whether the compressor is driven via gear, belt-pulley, or coupling, this component ensures the drive reaches the crankshaft in a perfectly centered position.

Vehicle and engine compatibility

This specific flange is compatible with Volvo FH12 models, including variants such as the FH 12/380, FH 12/500, FH 12/460, FH 12/420, and FH 12/340. It is engineered to withstand the rigorous operating conditions found in heavy commercial vehicle air brake systems.

Installation and maintenance guidance

For technicians performing maintenance or repairs, it is crucial to verify that the pilot diameter, bolt hole circle, and seal seat size match the original equipment specifications. Even if a part appears to fit, any mismatch in these dimensions can lead to rapid leakage or excessive vibration. Always consult your authorized distributor for precise fitment confirmation.

Troubleshooting and inspection

Regular inspection of the flange during air compressor servicing can prevent significant system failures. Checking for wear on the bearing seat or irregularities on the flange thickness can help avoid downtime in fleet operations.
