T2-2-1369A – Flange Yokes – 1330 Series – Bolt Circle Dia 4.250″ – Pilot Dia 2.000, F

1330 Series Flange Yoke T2-2-1369A -- Technical Buyer's Guide

Replacing a flange yoke without cross-referencing the dimensions is a gamble that typically ends at the parts bench, not the installation bay. The T2-2-1369A is dimensioned for 1330 series applications with a 4.250" bolt circle companion flange, 4 bolt holes at 0.500" diameter, and a 2.000" female (recessed) pilot. All three of those measurements must align with the mating component for the installation to succeed. This page gives you everything you need to confirm the fit before you add to cart.

Pilot Diameter and Runout

Runout is the enemy of long u-joint life. Even a few thousandths of an inch of offset at the flange yoke multiplies into significant angular oscillation at operating speed, accelerating wear on caps, seals, and needle bearings. The 2.000" female (recessed) pilot on the T2-2-1369A is machined to close tolerances to eliminate this source of runout before it starts. A properly seated pilot effectively absorbs the alignment burden, leaving the bolt pattern to handle clamping force only.

Assembly Requirements

• Degrease both mating faces before assembly -- oil contamination reduces effective friction and clamping
• Use a calibrated torque wrench; guessing torque on a flange bolt is a liability
• The 4-bolt pattern should be torqued in multiple passes, not a single sweep
• After torque is achieved, mark each bolt head with paint pen -- rotate the shaft by hand and verify no mark has moved
• If the vehicle will see sustained highway speeds, perform a short balance check run before final sign-off

Application Summary

The T2-2-1369A is classified as a standard 1330 series flange yoke for bolt-on companion flange applications. It is stocked by Universal Driveshafts for immediate fulfillment and ships with no additional hardware, as bolt selection depends on the thread specification of the companion flange. Order the correct fastener grade (at minimum grade 8 SAE or 10.9 metric) separately if they are not already on hand.
