3097150 Volvo B7 Compressor Crankshaft Flange

What does a crankshaft flange do?

The compressor crankshaft flange serves as a vital connecting component 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 compressor housing and the crankshaft. This component is essential for maintaining the structural integrity of the air compression cycle.

Vehicle and engine compatibility

This specific flange is compatible with Volvo B7 air brake compressors. It is engineered to withstand the high-stress environment of heavy commercial vehicle engines, ensuring that the drive force from the engine is transmitted to the compressor without excessive vibration or misalignment.

Installation and maintenance guidance

To ensure correct installation, technicians should verify that the flange matches the compressor type number. Proper alignment is critical; any mismatch in pilot diameter or bolt hole patterns can lead to premature seal failure or increased vibration within the pneumatic system. Regular inspection of the flange seat and mounting points can prevent unexpected downtime in fleet operations.
