When working with the 40006885 Yoke Shaft, it’s crucial to ensure proper fit and function. This component is part of the 3R series, featuring a spline count of 32 and a spline diameter of 1.375 inches. The spline length measures 3.350 inches, and the centerline to end distance is 7.810 inches. This yoke is specifically designed for Auto Trac Transfer applications, making it essential for maintaining driveline performance.
Before installation, check the spline engagement depth to ensure a snug fit. A common mistake is mismatching spline counts, so verify that the 32 splines align correctly with the mating component. Additionally, ensure that the boot cap part, N2112504 or 3R18-321, is compatible and in good condition to prevent any leaks or failures.
- Check spline count: 32 splines are required for proper fit.
- Verify spline diameter: 1.375″ is standard for this series.
- Measure spline length: Ensure it is 3.350″ for correct installation.
- Confirm centerline to end measurement: Should be 7.810″.
- Inspect boot cap part: Use N2112504 or 3R18-321 for optimal performance.
By following these guidelines, you can ensure that the 40006885 Yoke Shaft integrates seamlessly into your driveline system, maintaining the efficiency and reliability of your Auto Trac Transfer setup.
