Useful Information

Description and Purpose:

The Engine Flywheel Assembly delivered in new condition produced by Genuine Cummins is offered under Part Number: 3903416. It is designed to store and regulate rotational energy from the crankshaft, ensuring smoother engine operation and reliable starter engagement. This assembly supports consistent drivetrain connection and is compatible with Cummins ISB, ISD, ISF, ISG, B-Series (4.5L/6.7L), and QSB applications. Cross Reference: 3903420.

Why Replacement is Important:

Wear on the ring gear teeth or flywheel surface can lead to poor starting performance, noise during cranking, or uneven engine operation over time.

Impact on Vehicle Performance:

A new flywheel helps maintain smooth engine rotation, improves starter engagement accuracy, and reduces vibration transmitted through the drivetrain system.
