1697769 Crankshaft Flange for Volvo F7 TD70

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. By carrying the bearing and seal seat on the drive side, it facilitates the centering, sealing, and load transfer duties between the compressor housing and the crankshaft. This component is vital for preventing vibrations and ensuring a stable connection under heavy-duty operating conditions.

Vehicle and engine compatibility

This specific flange is designed for use in Volvo F7 trucks equipped with TD70 engines. It provides the necessary structural integrity required for heavy commercial vehicle applications, ensuring that the drive mechanism—whether gear, belt-pulley, or coupling—reaches the crankshaft in a perfectly centered position.

Installation and maintenance guidance

When performing maintenance or repairs, technicians should verify that all mounting dimensions align with existing requirements. Proper installation of this component is critical to prevent air leakage or excessive vibration within the pneumatic system. Check the compatibility list to ensure exact fitment for your specific compressor configuration.

Troubleshooting and inspection

Regular inspection of the flange and its seating surfaces can prevent secondary damage to the compressor housing or crankshaft bearings.
