It just showed up in my email today. http://www.enform.ca/Attachments/safety_Alerts/sa09_12.pdf
as usual, I just learned something. No idea PTO U joints had to be kept in phase
Normal farm shafts can be slid into each other in two ways, 180 degrees opposed. These dont have that problem. But if you have a cardan shaft, lets say a 20 ?? (just guessing something) spline shaft between engine and transmission of a wheel loader, you can get strange vibrations if you slide them out and put back under the wrong angle: Normally both ends equal each other out, but if they are wrongly positioned on the shaft, the shaft will vibrate violently. You can search for days, if you cant remember that your pal had that shaft apart the day before..
