20701801 S3 Crankshaft Flange for Volvo FH16 D16C

The compressor crankshaft flange acts as a vital 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 the essential duties of centering, sealing, and load transfer between the housing and the crankshaft. This component ensures that the drive—whether via gear, belt-pulley, or coupling—reaches the crankshaft in a perfectly centered position.

This specific flange is compatible with Volvo FH16 vehicles featuring D16C engines. It is engineered to withstand the high-pressure environments found in heavy commercial vehicle air brake systems, providing a stable interface for optimal compressor performance.

When replacing this component, technicians should verify the pilot diameter, bolt hole circle, and seal seat size to prevent vibration or leakage. Proper installation ensures that the centering and load transfer duties are maintained throughout the service life of the compressor.
