3102-217 – Flange Yokes – 1310 Series – Bolt Circle Dia 3.937″ – Pilot Dia 2.162, F”,

The 3102-217 Flange Yoke is a critical component for connecting driveshafts to transmissions, transfer cases, or differentials, specifically designed for 1310 Series applications. This yoke features a bolt circle diameter of 3.937 inches, a pilot diameter of 2.162 inches, and a bolt hole diameter of 0.489 inches. Understanding these dimensions is essential for ensuring compatibility with your driveline setup.

One of the key aspects of the 3102-217 is its 1310 Series designation, which dictates the U-joint cap diameter and cross width. If you mistakenly use a yoke from a different series, such as the 1350, you may find that the U-joint will not fit correctly, leading to potential failure or misalignment. This yoke’s four bolt holes provide a secure attachment to companion flanges, ensuring a robust connection.

• Series: 1310
• Bolt Circle Diameter: 3.937 inches
• Pilot Diameter: 2.162 inches
• Bolt Hole Diameter: 0.489 inches
• Cj to Flat: 2.082 inches

When installing the 3102-217, always check the spline engagement depth and verify phasing with the opposite yoke. Never force the spline entry, as this can cause damage. The precision of this yoke ensures that your driveline operates smoothly and efficiently, making it an essential part of your vehicle’s performance.
