When fitting the 2-1-1313-4, verify the output shaft diameter is 1.250" and the keyway width is 0.312" before pressing the flange onto the shaft. The front pilot diameter of 2.375" must match the companion flange receiver on the transmission or axle housing. The 3.125" bolt circle must align with the mating companion flange bolt pattern.
Confirm both the bore/keyway and pilot diameter dimensions against the transmission output shaft and companion flange specification before ordering. The 3.875" outside diameter sets the maximum clearance envelope for this flange yoke installation.
