2687404700040 Weld Tube Yoke 47.6×135 , 2040 Ser’ 68740 Fits Tube: 100×3.875 Butt Diameter: 92.25

2687404700040 UDS 68740 Series Weld Tube Yoke

The 2687404700040 is a UDS steel weld tube yoke in the 68740 / 2040 series, designed for a 100 x 3.875 mm driveshaft tube. The butt diameter measures 92.25 mm and the centerline-to-weld dimension is 100 mm. This yoke is welded onto the cut end of a heavy-duty metric driveshaft tube and accepts the 68740/2040 series U-joint interface at its ears.

Specifications

• Part Number: 2687404700040
• Brand: UDS
• Series: 68740 / 2040

• Center U-Joint to Weld: 100 mm

When fitting the 2687404700040, verify the tube OD is exactly 100 mm with a 3.875 mm wall. The 92.25 mm butt diameter pilots into the tube bore (100 mm OD minus 2 x 3.875 mm wall = approximately 92.25 mm ID), indicating a near-zero clearance fit that requires a straight, square tube cut for proper weld preparation. The 100 mm CL-to-weld must be included in driveshaft length calculations.

The 2687404700040 is a 68740 series part commonly used on medium to heavy commercial vehicles in metric-standard markets. Pair this yoke with 68740/2040 series U-joints and companion yokes. Do not mix with SAE series components, as the cap dimensions are not interchangeable. Verify tube OD and wall spec before welding.
