I'm trying to find a replacement u-joint for my IH model 80 snowblower PTO shaft. The bearing caps are plain with no grooves. Snap rings are on the outside of the cap in the yokes. Cap measures 1.250" in diameter. I measured the cap to cap outside dimension at 3.215". The joint is greasable and was originally Spicer. Ive spent an hour looking online at size charts but find them extremely confusing and contradictory and cant come up with any match. Can anyone shed any light on this? Cant believe it can be this difficult.

56Utility probably recognized it. I found it with a quick google search, which brought up AgriSupply.
Realizing that the cross is probably one of a few standard sizes, and knowing AgriSupply has a good selection, I started looking at crosses that looked right in the picture. For example I eliminated all the ones with internal clips. Then I started looking at ones with the external clips.

They might just have one on the shelf at the local Tractor Supply:

My post with the link to the u-joint at your local tractor supply store got ghosted. I won't post a link this time but I will say that there is probably one on the shelf at your local store.

Confusing is right! I had to replace some U-joints on my batwing mower last month. It is old and most of the drivelines have been replaced over the years, but
the four U-joints I needed appeared identical. I spent several hours looking on the internet trying to find a match, and I found the same confusion and
contradictions. I finally thought I had it figured out and ordered what I needed. Two of the four worked fine. One joint was OK in all respects except that the
bearing caps were the wrong diameter, just small enough that they were a very loose fit in the yoke. I used the old caps and it worked fine. The last one was
correct in all respects except the bearing caps were about .020 too long. I never found a good source of info on the internet. If anyone can point me to a
good reference guide that explains U-joints, I'd sure appreciate it.

There's no true "standard" for universal joints so it's a matter of:
A. Knowing what you have.
-or in absence of that-
B. Matching it up, and then remembering what you have.
This is where local in-person interaction is a bonus. Any local farm equipment dealer can match most PTO universals unless it is some proprietary size. Then you have to either replace the whole driveline with something standard, or get a factory part.
MANY, perhaps even most, PTO universals are either Weasler or based on the Weasler "standard." Especially older ones. In this case it was their "Series 35." Other common ones are Series 6 and Series 12.
