3-28-547 -- Spicer 1480 Weld Yoke, 3.500x0.083 Tube

The 3-28-547 is the Spicer-branded 1480-series weld yoke for 3.500"x0.083" tube -- the thinner wall variant compared to the 3-28-567 (0.095" wall). The wall difference of 0.012" per side produces a 0.023" butt diameter difference (3.344" vs. 3.321"). While this might seem trivial, at 3.500" tube the 0.023" difference represents a meaningful proportion of the pilot clearance -- a 3.321" butt inserted into a tube bored for 3.344" will have 0.023" radial clearance (0.0115" per side), which is enough to allow the yoke to sit off-center before tack welding if not hand-held during tacking. Always match the butt diameter to the actual tube wall in your application.

Spicer-branded components in this series are machined to tighter dimensional tolerances than generic aftermarket alternatives, which benefits final assembly balance. The Spicer 1480 joint (cross-reference 5-280X) uses a proprietary needle bearing geometry in the 1.375" cap that provides higher dynamic load capacity than generic replacements at the same nominal cap OD. For production-quality truck driveshaft repairs, use Spicer components throughout the assembly.
