Application

When purchasing U-Joints, 3 easy steps will help ensure that they will be correct for your application.

STEP 1
Be sure to measure the diameter of the shaft and count the number of splines on the shaft. Some shafts have a blank spot ground on one side. To get the correct number of splines, use a flat edge and cover the blank half of the shaft through the diameter and count the splines on the other half. Multiply that number by 2, thus giving you the total number of splines on the full circumference of the shaft.

STEP 2
Choose which shaft type best suits your application: 3/4" weld on, 3/4" DD or 1" DD.

STEP 3
With these two pieces of information at hand, refer to our chart to find the appropriate part number of the u-joint for your specific application.
