PTO question

Hopefully this doesn't belong in the drivetrain section.

How does the u-joint come off of the PTO on the side of the NP435? It is broken and and needs replacement. I don't see a pinch screw on the side. I assume there are splines, but I'm just not sure how to remove it from the PTO yoke.

Thanks guys. I'll look again for a set screw. I didn't see one the first time I looked.

The set up I had was a two piece. I was thinking I could use a one piece drive shaft. That way I could just use the middle u-joint on the PTO yoke and the other on the pump. Therefore elliminating the need for a new u-joint. The only thing is trying to slip the shaft into the u-joints. I think that's why the two piece set up is used. Maybe I could just take the PTO off slip the shaft into the u-joint and reattach it.

Any comments are welcomed.

Any ideas if my idea will work?

A single PTO shaft should work fine, but you should have a slip joint in the shaft so things don't bind up when the engine/tranny move a bit in thier mounts. I've bought PTO driveshaft yokes and pieces over the counter at Napa.

Thanks for the info. At least I know here I can get the u-joint if I need it. I think I'll prooly just get a new u-joint. I really should do it the right way. It can't be that much $.
