3090385 Volvo F7 TD70 Compressor Crankshaft Flange

What does a crankshaft flange do?

The crankshaft flange acts 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, it performs the essential duties of centering, sealing, and load transfer between the compressor housing and the crankshaft.

Compatible vehicles and engines

This specific component is designed for use in Volvo F7 trucks featuring TD70 engines. It provides the necessary stability to ensure that drive forces—whether transmitted via gear, belt-pulley, or coupling—are transferred accurately to the compressor assembly.

Installation and maintenance

To ensure a correct fitment, technicians should verify that the flange dimensions match the existing unit, specifically focusing on the pilot diameter, bolt hole circle, and seal seat size. Using an incorrect flange can lead to premature vibration or air leakage within the pneumatic system.

Troubleshooting and selection

Maintenance should focus on inspecting the flange for any signs of uneven wear or mounting surface irregularities during routine compressor service. Always consult your authorized distributor to confirm exact fitment for your specific engine configuration.
