1697769 Crankshaft Flange for Volvo F12 TD120

What does a crankshaft flange do?

The compressor crankshaft flange serves as a critical connecting element that links the air brake compressor's crankshaft to the engine drive. It performs the essential duty of centering, sealing, and transferring loads between the compressor housing and the crankshaft. By providing a stable seat for bearings and seals on the drive side, it ensures the drive mechanism—whether gear, pulley, or coupling—reaches the crankshaft accurately.

Vehicle and engine compatibility

This specific flange is designed for Volvo F12 trucks equipped with TD120 engines. It is also compatible with various Volvo F12 variants such as the F 12/370, F 12/360, F 12/400, F 12/410, F 12/320, and F 12/330 models. Ensuring the correct fitment for these heavy commercial vehicle engines is vital to prevent vibrations or air leakage.

Installation and maintenance guidance

For workshop technicians performing maintenance, it is important to verify the pilot diameter and bolt hole configuration during installation. Proper alignment is necessary to prevent premature wear of the seals and bearings. When replacing this component, always inspect the drive interface to ensure no debris interferes with the seating surface.

Ensuring correct fitment

Selecting a high-strength component ensures that the load transfer remains consistent under high-pressure operating conditions. Consult your authorized distributor to ensure exact fitment for your specific compressor configuration.
