零件号 3102-9048 (也写作 3102/9048) 法兰叉 1310, Bolt Circle 2.933,定位: 1.850- Flange OD: 90MM, 2-2-1329

Flange Yoke 3102-9048 -- 1310 Series, 2.933" Bolt Circle

Sourced directly from the drivetrain component specialists at Universal Driveshafts, the 3102-9048 is a 1310 series flange yoke machined to consistent, measurable tolerances. It is purpose-built for applications where the driveshaft must bolt directly to a companion differential or transfer case flange rather than slip over a spline. The 1.850" female (recessed) pilot feature ensures immediate concentricity the moment the yoke is seated.

Technical Data

How the Bolt Circle Drives Compatibility

The 2.933" bolt circle is the defining compatibility dimension -- it must match the companion flange exactly. Attempting to use a yoke with a different bolt circle leads to misaligned holes, requiring elongation that destroys the precision fit. The 3102-9048 is stocked specifically for flanges with a 2.933" PCD, so there is no guesswork at the bench. It ships with 4 bolt holes of 0.315" diameter, ready for standard or metric hardware depending on your vehicle platform.

Pre-Installation Checklist

• Measure companion flange bolt circle -- must equal 2.933"
• Confirm pilot diameter of mating flange matches 1.850" female (recessed) pilot
• Check that your u-joint series is 1310 -- cap size compatibility is non-negotiable
• Verify CJ-to-flat (1.930") against cap depth in your u-joint to prevent interference
• Clean and de-burr both mating faces before final assembly

Build Quality

Every 3102-9048 is forged from carbon steel for grain-flow strength, then machined to finished dimensions. The ear bores are sized for 1310 series cap diameter -- no reaming required. Whether this is a stock replacement or part of a custom high-performance build, the part will handle the torque loads the 1310 series was rated for without deflection or fretting at the bolt faces.
