Detailed Description

SKF BD35 is an engine cooling fan hub engineered around bearing precision, with a 1.378-inch inside diameter, 2.520-inch outside diameter, and 1.457-inch width. Those dimensions matter when servicing the fan drive assembly because proper bearing fit helps maintain stable fan operation and consistent cooling performance. This part is a strong match for Ram 2500, Ram 3500, and earlier Dodge D250, D350, W250, and W350 trucks across the listed model years. This part number, BD35, is also referenced by 04429639 for the same application.

What It Helps Address

• Excessive fan hub play or looseness
• Noise from a worn cooling fan hub bearing
• Irregular fan rotation in the cooling system
• Cooling system service on Ram 2500 and Ram 3500 trucks
• Cooling fan support issues on Dodge D250, D350, W250, and W350 models

Installation Notes and Tips

Verify the hub dimensions against the original part before installation. Inspect the fan drive components, mounting surfaces, and surrounding cooling system parts for wear or damage before reassembly. Confirm the application by year, make, and model for Ram 2500, Ram 3500, and the listed Dodge truck fitments. The part number BD35 should be matched carefully to the existing hub specification during service.
