1697769 Compatible Compressor Crankshaft Flange

The compressor crankshaft flange serves as the vital 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 of the crankshaft, it performs the essential duties of centering, sealing, and load transfer between the housing and the crankshaft. This component ensures that the drive mechanism reaches the crankshaft in a perfectly centered position to prevent premature wear.

This specific flange is designed for compatibility with Volvo FL models, including various configurations such as the FL 180, FL 220, and FL 250 series, as well as several FL 7 variants. It is engineered to meet the rigorous demands of heavy commercial vehicle service environments.

When replacing this component, technicians should verify that all dimensions such as pilot diameter, bolt hole circle, and flange thickness match the original part exactly. Incorrect fitment can lead to immediate leakage or excessive vibration. For optimal performance, ensure all mounting surfaces are clean and that the seal seat is properly seated during installation.

Maintaining the integrity of the crankshaft flange is crucial for preventing air leaks and ensuring consistent pressure delivery within the pneumatic braking system.
