3090385 Crankshaft Flange for Volvo B10

What does a crankshaft flange do?

This compressor crankshaft flange serves as the essential 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 vital centering, sealing, and load transfer duties between the compressor housing and the crankshaft.

Vehicle compatibility and fitment

This component is specifically designed for compatibility with Volvo B10 engines and systems. By maintaining precise alignment between the drive mechanism and the crankshaft, it prevents premature wear and ensures consistent air pressure delivery in heavy commercial vehicle applications.

Installation and maintenance guidance

When performing maintenance, technicians should verify that the flange matches the existing unit's pilot diameter, bolt hole circle, and seal seat size. Ensuring these dimensions match is critical to prevent vibration or air leakage within the pneumatic system.

Importance of precision fitment

Proper installation of this high-strength component is necessary to maintain the integrity of the air brake compressor assembly under heavy-duty operating conditions.
