3090385 Crankshaft Flange Compatible with Volvo FL

The compressor crankshaft flange serves as a critical 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 housing and the crankshaft. This ensures that the drive, whether via gear, pulley, or coupling, remains perfectly aligned.

This specific flange is designed for compatibility with Volvo FL series models, including various FL 180, 220, and 250 variants, as well as FL 7 models. It is engineered to meet the rigorous demands of heavy commercial vehicle systems, providing a reliable interface within the air brake compressor assembly.

For successful installation, technicians should verify that all dimensions such as pilot diameter, bolt hole circle, and seal seat size match the existing component exactly. Incorrect fitment can lead to premature leakage or excessive vibration. Proper inspection of the crankshaft seating area during replacement is recommended to ensure long-term reliability.

Consult your authorized distributor to ensure correct fitment for your specific engine configuration.
