3326-272 – Weld Yokes – 1330 Series – Butt Dia 2.594″ – Tube Dia Wall 2.750X0.083

Q: Why does the center-to-weld dimension matter on a weld yoke repair? A: When replacing one weld yoke on an existing shaft, the center-to-weld distance on the new yoke must match the original to keep the overall shaft length and phasing unchanged. The 3326-272 uses 1.719" center-to-weld. If the original yoke used 1.688" or 1.750", the shaft length will be off by the difference -- which shifts the working angle at one end and can cause vibration. Q: What Spicer part is equivalent? A: The Spicer/Dana catalog references the 3-28-272 series for 1330 weld yokes on 2.750" tube. Neapco catalogs comparable parts under the 2-0027 series. Always confirm series compatibility before cross-referencing. Q: Is 2.750x0.083 steel adequate for towing? A: For half-ton truck rear driveshafts in the 600--800 ft-lb torque range, 2.750" x 0.083" steel tube is appropriate. Verify the weld yoke series matches the U-joint cross -- a mismatched series (e.g., 1310 yoke with 1330 cross) will not accept the larger cap diameter. Q: What filler wire for welding? A: For mild steel to 1020 DOM tubing, ER70S-6 filler is standard. Full-penetration fillet weld at the butt joint; inspect with dye penetrant on safety-critical rear shafts.
