Specifications
- Part Number: 3-40-1871U

- Spline Count x Diameter: 16 x 1.562"
- Spline Length: 3.000"

When fitting the 3-40-1871U, verify the mating slip yoke bore is 16 splines at 1.562-inch diameter, and confirm the tube is 3.500-inch OD with a 0.083-inch wall before welding. The 3.344-inch butt diameter seats into the tube ID — tube prep and concentricity are essential on a thin-wall 0.083-inch tube to maintain alignment.
The 3-40-1871U is a stub shaft component for use in two-piece driveshaft assemblies that require a 1.562-inch spline interface. The 8.750-inch end-to-weld dimension represents the full stub length. When selecting between similar stub shafts for 3.500-inch tube, cross-reference spline diameter — 1.562-inch here differs from the 1.750-inch used on the 4-40-721U and the 2.000-inch used on the 5-40-1191U.
