3R-28-437 Weld Tube Yoke 3R , Fits: 3.000x 0.083 Tube , Butt: 2.844 Inch Centerline To Weld: 1.875

3R-28-437 UDS 3R Series Steel Weld Yoke 3.000x0.083 Tube 2.844 Butt 1.875 CL-to-Weld

The 3R-28-437 is a UDS steel weld yoke in the 3R series, designed to fit 3.000" OD x 0.083" wall driveshaft tube. The butt diameter is 2.844" and the center U-joint to weld distance is 1.875". The 3R series designation identifies a specific yoke geometry — confirm the companion U-joint and mating yoke series match 3R before assembly.

Specifications

• Part Number: 3R-28-437
• Brand: UDS
• Series: 3R
• Material: Steel
• Tube Dia x Wall: 3.000" x 0.083"
• Butt Diameter: 2.844"
• Center U-Joint to Weld: 1.875"

When fitting the 3R-28-437, the driveshaft tube must be exactly 3.000" OD and 0.083" wall — the 2.844" butt diameter provides the shoulder that the tube end seats against prior to welding. The 1.875" center U-joint to weld dimension establishes the geometric relationship between the U-joint working centerline and the weld joint; verify this fits within the available driveline envelope. Confirm weld procedure is appropriate for the tube and yoke material combination. The 3R-28-437 is steel construction, appropriate for standard driveline weld procedures. The 3R series yoke must be paired with 3R-compatible U-joints; confirm cap dimensions are appropriate for this series before assembly. Verify tube OD and wall thickness against shaft specifications before welding the 3R-28-437.
