3102-1280 – Flange Yokes – 1310 Series – Bolt Circle Dia 3.970″ – Pilot Dia 2.940-F

3102-1280 is a Flange Yoke designed for 1310 Series applications, featuring critical dimensions that ensure compatibility and performance. The 3.970-inch bolt circle diameter is essential for a secure attachment to the companion flange, providing the necessary stability during operation. This dimension directly influences how well the yoke aligns with the driveshaft and the overall driveline geometry.

The pilot diameter of 2.940 inches allows for a precise fit, which is crucial in maintaining the integrity of the connection. A snug fit reduces the risk of vibration and wear, extending the lifespan of both the yoke and the connected components. With eight bolt holes, each measuring 0.394 inches in diameter, this yoke offers ample fastening points to ensure a robust connection.

• Series: 1310
