3502-0165 UDS Flange Yoke 1350 Series – Aluminum 6061-T6 Tri Flange

Yoke selection is critical to driveshaft longevity -- mismatched piloting or bolt geometry generates imbalance that accelerates U-joint wear. The 3502-0165U flange yoke is dimensioned to Series 1350 standards, ensuring correct piloting, bolt engagement, and U-joint ear geometry for a vibration-free assembly. Pilot diameter: 0.630". Bolt circle: 4.528".

Technical Specifications -- 3502-0165U

Fitment & Mating Flange Specs

The 3502-0165U is compatible with all Series 1350 companion flanges and yoke bores meeting the published dimensional standard. The 0.630" pilot diameter is a precision ground fit that centers the yoke concentrically on the mating component. Four bolt holes on a 4.528" 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.

Assembly Notes

Install the 3502-0165U 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
