Problem: Today, there are literally hundreds of PTO sizes.In order to properly identify an agricultural PTO, you must determine who made it (the Vendor) or who was being copied. The universal joint size is the number one required specification, followed closely by tubing shape and dimensions.

|
1) Measure the universal joint cup diameter using a pair of calipers.Our U-joint table is indexed by cup diameter using milimeters. See conversion form at the bottom of this page. |
 |
2) Measure the length of the universal joint with the caps on.* Note: If the U-joint uses inside rings, please measure the distance between them also. |
 |
3) Notice the shape of the tubing and measure it.We are trying to identify the manufacturer. Who made it?
|
|
4) If the assembly is splined it may belong to any of the vendors.Measure the outside diameter of the splines and count their number. Also, measure the outside diameter of the round tube. |
|
5) Now that you have all the needed measurements, you may either use our universal joint table to identify your part, orcall Drive Line Service of Fresno - 800-824-0706.
