4102-1288 – Flange Yokes – 1410 Series – Bolt Circle Dia 4.000″ – Pilot Dia 2.950, F

The 4102-1288 Flange Yoke is a crucial component in your driveline, connecting the driveshaft to the transmission, transfer case, or differential. With a bolt circle diameter of 4.000 inches, this yoke ensures a secure fit, allowing for reliable power transfer. The 2.950-inch pilot diameter plays a vital role in centering the driveshaft, which is essential for maintaining balance and reducing vibration during operation.

This yoke is specifically designed for 1410 Series applications, which means it accommodates U-joints with a particular cap diameter and cross width. The 8 bolt holes, each with a diameter of 0.315 inches, provide ample fastening points to secure the yoke to the companion flange or other driveline components. The Cj to flat measurement of 2.250 inches is also critical, as it determines the positioning of the yoke in relation to the driveshaft.

• Check spline engagement depth during installation.
• Ensure proper phasing with the opposite yoke to avoid driveline vibrations.
• Never force spline entry; it can lead to premature wear or failure.
• Inspect the mating components for wear to maintain system integrity.
• Use appropriate torque specifications for the bolt holes to secure the yoke properly.

In summary, the 4102-1288 Flange Yoke is engineered for durability and performance in demanding applications. Its precise dimensions and compatibility with the 1410 Series make it an essential part of any driveline system.
