About 4103-343
The difference between 4103-343 and 4103-342 is the counterbore: 4103-343 has a 1.564" counterbore while 4103-342 has none. The counterbore pilots against the transmission output bearing retainer OD -- if your transmission housing requires this centering feature, installing 4103-342 (without counterbore) will allow the yoke to run off-center and create vibration. Measure the output retainer OD before deciding between the two variants.
- Series: 1410 -- 1.188" U-joint cap diameter
- Finish: Nickel Plated -- corrosion resistance without affecting structural performance
- Splines: 33/34 x 1.625"
- C/U-joint to end: 8.110"
- Hub diameter: 2.086" -- verify tail housing seal bore before ordering
- Counterbore: 1.564" -- measure the output retainer OD; should be a close slip fit in the counterbore
Nickel plating on this 1410 yoke improves corrosion resistance in wet or salt-exposed environments. The plating is applied after machining, so critical dimensions (hub OD, spline form, counterbore) are finished to specification before the plating step.
