4103-343 – Transmission Yokes – 1410 Series – 33/34 X 1.551 Splines – 2.086″ Hub Dia

When you’re ready to install the 4103-343 Transmission Yoke, make sure to check the spline count first. This yoke features a 1410 Series build with a spline count of 33/34 and a diameter of 1.551 inches. It’s crucial to ensure that the yoke fits the corresponding U-joint properly, as mismatches can lead to premature wear or failure.

The hub diameter measures 2.086 inches, while the counterbore diameter is 1.564 inches. These dimensions are critical for ensuring a snug fit and proper alignment with the transmission or differential. The distance from the center U-joint to the end of the spline is 8.110 inches, which is essential for maintaining the correct driveshaft length and phasing.

Before installation, verify that the spline engagement depth is adequate and that the yoke is aligned correctly with the opposite yoke. A common mistake is forcing the spline entry, which can damage both the yoke and the transmission output. Remember, this yoke is nickel-plated, enhancing its durability and resistance to corrosion.

• Check spline count against the output shaft before installation.
• Ensure proper alignment with the opposite yoke to avoid vibration issues.
• Inspect the mating surfaces for wear or damage prior to installation.
• Do not force the spline entry; it should slide on smoothly.
• Torque fasteners to the manufacturer’s specifications for secure attachment.

In summary, the 4103-343 Transmission Yoke is a reliable choice for heavy-duty applications, combining robust design with practical features for easy installation.
