4102-1839 Flange Yoke 1410 Ser’ 2C3Z4865BA Pilot: Female 2.953 Bolt Circle Diameter 4.750 Ford 3-2-1839 Common on Ford Excursion and Trucks

When diagnosing driveline issues, the 4102-1839 Flange Yoke is a critical component to consider, especially in 1410 Series applications. This yoke connects the driveshaft to the transmission or differential, and its specifications are vital for proper function. If you notice vibrations or a clunking noise during acceleration, it could indicate a worn or damaged yoke. A failure in this component can lead to misalignment, causing premature wear on the U-joint and other driveline parts.

The 4102-1839 features a bolt circle diameter of 4.750 inches and a pilot diameter of 2.953 inches, which are essential for ensuring a secure fit. The four bolt holes, each with a diameter of 0.500 inches, allow for robust attachment to the companion flange. Additionally, the length from the center of the universal joint to the flat face is 2.000 inches, which is crucial for maintaining the correct phasing with the opposite yoke.

• Check spline engagement depth before installation.
• Verify phasing with the opposite yoke to prevent vibrations.
• Ensure all bolt holes are clear and free from debris.
• Torque fasteners to the manufacturer’s specifications for optimal performance.

Using the 4102-1839 Flange Yoke restores proper torque transfer and alignment in your driveline, ensuring a smooth and efficient operation. Don’t overlook this component when troubleshooting driveline issues.
