Viewing a thread - Determining triangle pto shaft series?

WCINSo I bent the two tubes on a triangle pto shaft (both yokes are fine ) and after some internet searching have found I can rebuild shafts for about 1/4 dealer price at parts counter. Problem is I don't know how to determine shaft "series"? Two welding shops I stopped at had never seen it, didn't know what it was and could maybe get it in a couple weeks. eBay has gobs, just want to make sure I order right. Thanks.

THe cross width the main determinant on those shafts. A class 6 will have a 92mm cross and the class 5 will have about 80mm or whatever is on that chart. Internal tubes are the same on the 5 and 6. External tube on the 6 is thicker...

Hi,

Been googling around but can't find the info yet. I need a new pto shaft and wondering what series I need?

This will go on a 4ft brush hog. There is lots of info on determining pto series but not what series pto a shaft a particular implement requires.

How do you properly size the series (not the length)

Thanks.

Sent from my iPhone using Tapatalk Thanks Pat. How are these things sized? How can I make this determination myself without posting online and hoping an implement dealer responds? [emoji3]Are they rated by hp or ...?

Thanks!

Sent from my iPhone using Tapatalk It's up to the original manufacturer on what size they use! Yes certain for certain HP driven implements.

FYI below is a detailed in matching parts, but comes into play for determining sizing.

There is a certain amount of knowledge. Measure the cross cup diameter size and width across the cross/spider itself to determine the size and series. Also internal/external snap rings. Then you can match yokes, shafting style and shielding.

And each piece mentioned above has it's own sub categories, for instance shafting: rectangular, lemon, tri-lobe, splined, dimpled. And we have not hit US or metric (usually a puke yellow color yoke) and shaft wall size.
