3102-1789 – Flange Yokes – 1310 Series – Bolt Circle Dia 3.750″ – Pilot Dia 2.750, M

3102-1789 is a Flange Yoke that plays a crucial role in connecting driveshafts to various driveline components. This yoke features a 1310 Series configuration, which is well-known for its balance between strength and weight. The 3.750-inch bolt circle diameter ensures compatibility with a wide range of applications, while the 2.750-inch male pilot diameter provides a secure fit to the mating component.

Engineers designed the 3102-1789 to handle the torque loads typical in performance and heavy-duty applications. The four bolt holes, each with a diameter of 0.398 inches, allow for easy installation and secure attachment to companion flanges. The Cj to flat measurement of 1.625 inches is optimized for proper alignment and phasing with the opposite yoke, which is critical for smooth operation and longevity of the driveline.

• Ensure proper spline engagement depth during installation.
• Verify phasing with the opposite yoke to prevent vibrations.
• Use appropriate torque specifications for bolt fasteners.
• Inspect mating components for wear to maintain system integrity.

In summary, the 3102-1789 Flange Yoke is engineered to deliver reliable performance, making it an essential component for any fabrication shop or fleet technician looking to maintain or upgrade their driveline systems.
