PTO shaft bearings
Posted: Fri Jan 21, 2022 3:50 pm
Since I am fixing this Cub up to mow with, and my PTO has probably seen a lot of use, I figured I might take the PTO apart this week end.
It appears to need at least the out side bearing as its pretty loose, and the grease zert is missing. So I will have to fix that.
Is this zert the only grease that the bearing get? Probably too high in the trans to lubricate off of the trans oil?
It looks like there is part of it still left in the hole, that will have to be removed. If I remember right zerts are hard as a rock, so that may be fun..
The PTO will spin very freely when you twist the shaft, probably a little freer than it should.
I tested the PTO when I first got the tractor and was giving it a going over. It was pretty quiet, but it was hard to tell with the mower on the tractor and running. I did noticed the shaft move in and out some.
After I got the mower off, and the pulley off, I can pull the shaft in and out about and 1/8 inch or a little more.
So something is wrong, and looking at the service and parts manuals there appears to be a snap ring in there on the shaft, behind the bearing.
Is this what holds the shaft from moving in and out? Maybe its missing? Maybe the bearings are just that worn?
I just kind of wanted to know what you all thought, before I tore into this part of the tractor.
I have not been into this part before, but I will soon know how it works too.
Well thanks for the help.
