About 2-28-1977
Q: The butt diameter on the 2-28-1977 is listed as 3.125" for a 3.500"x0.065" tube. Is this a stepped-bore design?
A: Yes -- the standard flush-pilot step-down for 3.500"x0.065" tube would be 3.370" (3.500" - 2x0.065" = 3.370" bore). A 3.125" butt is 0.245" smaller than the tube bore, confirming a stepped-bore yoke design similar to the Spicer 1410/Chrysler variants noted earlier. This means the yoke pilot engages an internal shoulder inside the tube rather than the tube face bore. Confirm the tube bore profile on your application before ordering.
Q: What is the advantage of the 1330 series over 1310 in a large tube like 3.500"?
A: The primary advantage is torque capacity and to a lesser extent angle tolerance. At 3.500" tube, the 1330 series is more appropriately matched to the tube's torsional capacity than the 1310 would be. Using a 1310 joint in a 3.500" tube application that sees peak torque events will cause the joint to fail before the tube shows any distress -- the limiting component is always the joint, not the tube, when a light series is under-specified.
Q: What Spicer U-joint does this weld yoke require?
A: Spicer 5-3250X or equivalent 1330-series joint at 1.062" cap OD with the 1330-specific cup depth. Verify by cross-reference catalog.
