4089222 Crankshaft Flange for Cummins QSC8.3 Engines

What does a crankshaft flange do?

This compressor crankshaft flange is a vital mechanical component designed to facilitate the connection between the crankshaft and the compressor assembly. It ensures the stable transfer of rotational motion, which is essential for the compression stroke in heavy commercial vehicle air brake systems. Built with high-strength components, it maintains structural integrity under high-pressure operating conditions.

Engine compatibility and fitment

This specific part is compatible with Cummins engines, including the QSC8.3, X12, QSB, QSX15, ISX, ISB6.7, ISX15, ISB, 6BT5.9, QSB6.7, QSL9, and ISC8.3 series. It is engineered to meet the rigorous demands of heavy commercial vehicle service environments.

Installation and maintenance

When performing maintenance or overhauling the compressor crankshaft assembly, technicians should inspect the flange for signs of wear or misalignment. Proper installation of this component is critical to prevent vibration and ensure the longevity of the air brake compressor's moving parts.

System reliability

Regular checks of the crankshaft assembly help prevent unexpected downtime in fleet operations. By replacing worn flanges with high-strength components, workshop technicians can ensure optimal pneumatic performance for the entire braking system.
