3501-311 is a critical component for adapting the Ford Transit Flex coupler to a flange setup, specifically designed for use with components 3502-1859 and 4102-1839. This Companion Flange features a spline count of 31, with a spline diameter of 1.387 inches, ensuring a secure fit into the corresponding yoke. The hub diameter measures 2.205 inches, providing the necessary support for the driveline assembly.
One of the key aspects of the 3501-311 is the bolt circle diameter of 4.750 inches. This dimension is crucial for ensuring proper alignment and stability when bolting to the differential or transmission output. The pilot diameter of 2.953 inches also plays a significant role in maintaining concentricity, which is essential to prevent vibration during operation.
When installing the 3501-311, it’s vital to ensure that the flange face is perpendicular to the rotational axis. Any runout can lead to undesirable vibrations, which can cause premature wear on other driveline components. Here are some tips for installation:
- Clean all mating surfaces thoroughly before installation.
- Torque bolts in a star pattern to ensure even pressure.
- Check the face runout after installation to confirm alignment.
With a through hole measuring 1.469 inches, the 3501-311 provides adequate clearance for various applications. This Companion Flange is an essential part for any Ford Transit conversion, ensuring reliable performance and durability in your driveline setup.
