When working with the 3301-1356 companion flange, it’s crucial to ensure proper fitment with the Borg Warner TC 1356 transfer case. This flange features a square pattern and a counterbore depth of 0.25 inches, making it essential for maintaining alignment and preventing vibration. Before installation, verify that the bolt circle diameter of 4.25 inches matches your application, and ensure the spline count of 31 aligns with your yoke.
Common mistakes during installation include neglecting to check the face runout. The flange face must be perpendicular to the rotational axis; any runout can lead to unwanted vibrations. Use a dial indicator to measure this before securing the bolts. Additionally, clean all mating surfaces thoroughly to ensure a proper seal and torque the bolts in a star pattern to the manufacturer’s specifications.
- Check the spline diameter of 1.380 inches against your yoke.
- Ensure the pilot diameter of 2.000 inches fits snugly in the transfer case.
- Confirm the through hole diameter of 2.000 inches is compatible with your setup.
- Inspect the hub diameter of 1.890 inches to avoid misalignment.
By paying attention to these details, you can ensure a smooth installation of the 3301-1356 companion flange, enhancing the performance and reliability of your driveline system.
