What bearing are toy talking about? There's a snap ring,then a plug that you pull out with a piece of half inch threaded rod. After you pull that out,there's an o-ring inside those splines that seals the gap between the splines and the plug. The plug is what holds up against the shaft.

The shaft that came out of the tractor is the approx. 12" PTO shaft that the implement shaft is hooked on to. When it came out there was a bearing on the shaft. The shaft looks like it splines into the rear housing. Once the shaft with bearing is inserted into the rear housing a snap ring holds it into place. The bearing was broke up from the brush hog shaft still turning after it had slipped out. I could not get a number off of it. I did not see a 1/2 " threaded rod.

OH,OK,I get what happened. I thought it was the one inside on the long shaft. Guess I had that one on my mind since I had to put a whole new shaft in mine last week.

Yeah I get that way too. Thinking of one thing and doing the other. LOL. I can break the bearing number and get it local and the oring. I'll have to order the snapring. This happened to me years ago. I was lucky. The bearing was ok and the snapring was there. I just put it back together. What would make this happen?

Don't know. I'm wondering if the groove gets worn or the temper goes out of the snap ring. Mine came out a few years ago while I was picking corn. Only happened once and never again. You'd think if it was going to do it,it would happen when I was running something that turns harder,like the haybine,where it might bind up in a turn or something.

The AGCO parts breakdown lists the bearing part number as: 158363A Bearing - Fafnir 208KRR4; in addition you will want to put on an o-ring to seal it to the shaft: K5709 "O" Ring - 1/8 x 3-1/8 ID.
