3502-0145 UDS Flange Yoke 1350 Series – Aluminum 6061-T6 Tri Flange

The 3502-0145U is a UDS Series 1350 flange yoke delivering OEM-matching performance for shaft assemblies that demand exact companion-flange matching. Piloted at 0.551" with a 4.134" bolt circle and 0.559" bolt holes, this yoke seats positively on the mating flange with no lateral float. Correct pilot fit is the foundation of a balanced, long-lasting drivetrain.

Technical Specifications -- 3502-0145U

Series Compatibility

The 3502-0145U is compatible with all Series 1350 companion flanges and yoke bores meeting the published dimensional standard. The 0.551" pilot diameter is a precision ground fit that centers the yoke concentrically on the mating component. Four bolt holes on a 4.134" bolt circle accept standard Series 1350 fasteners. Verify that the mating component -- whether a differential pinion flange, transfer case output, or transmission tailshaft -- specifies Series 1350 to ensure correct geometry.

Installation & Torque Guidance

Install the 3502-0145U with new fasteners torqued to the vehicle or equipment manufacturer's flange bolt specification. Clean the mating pilot bore and flange face before assembly to ensure full contact. Apply anti-seize compound to flange bolt threads if operating in a corrosive environment. Inspect the yoke ears and snap-ring grooves for burrs after installation of the U-joint cross.

• Use a torque wrench -- do not impact-gun flange bolts to final torque
• Re-torque flange bolts after the first 100 miles in service
• Balance the completed shaft assembly after yoke replacement on high-speed applications
