2-28-1757 Weld Tube Yoke 1310 Ser’ , Fits: 2.000 X 0.120 Butt Dia: 1.766

Q: Why use 0.120" wall on a 2.000" tube? A: A D/t ratio of 16.7 on 2.000" x 0.120" is extremely heavy-wall. This geometry is specified where the shaft is very short (under 12") and the application sees high torque pulses -- such as a transfer case front output stub or a short intermediate shaft in a 4WD system. The thick wall ensures the tube is never the weakest link; the U-joint cross becomes the torque fuse. Q: What is the torsional strength of this tube? A: 2.000" x 0.120" 1020 DOM steel has a torsional yield strength in excess of 3,000 ft-lb, far exceeding the 1310-series U-joint rating of approximately 1,200 ft-lb. The U-joint is the limiting component. Q: What is the Spicer cross-reference? A: The 2-28-1757 numbering follows Spicer catalog format. Compare to Dana/Spicer listings for 2.000" heavy-wall transfer case applications. Q: Can I use this with a 1330 cross? A: No -- this is a 1310-series weld yoke. The bore trunnion span is machined for the 1310 cross; installing a 1330 cross will produce excessive lateral play and rapid wear.
