1697769 Crankshaft Flange for Volvo F12 TD122

The compressor crankshaft flange acts as the essential connecting element that links the air brake compressor's crankshaft to the engine drive. This component carries the bearing and seal seat on the drive side of the crankshaft, performing critical duties such as centering, sealing, and load transfer between the housing and the crankshaft. By ensuring the drive reaches the crankshaft in a perfectly centered position, it prevents premature wear and leakage.

This specific component is designed for use in Volvo F12 trucks equipped with TD122 engines, including variants such as the F 12/370, F 12/360, F 12/400, F 12/410, F 12/320, and F 12/330. It is engineered to withstand the high-pressure environments found in heavy commercial vehicle pneumatic systems.

For proper installation, technicians should verify that the pilot diameter, bolt hole circle, and seal seat size match the existing unit to avoid vibration or air leakage. Regular inspection of the flange seat is recommended to ensure no debris interferes with the seal's integrity during engine operation.
