PTO shaft seal??

Eman85 · Oct 20, 2018

1977 2600 PTO is leaking a little. Any tips or tricks to replae this seal? I'm guessing 4 bolts and the plate comes off and the shaft pulls out.

It's been a lotta years but it's a simple process excluding what to do with the fluid. Best thing to do is leave it be until you are ready for a fluid change
and then drain the fluid and get after it.

be sure to place a drain pan underneath pto housing as you will lose several quarts of fluid. The entire
pto shaft will pull out with to 4 bolt housing.
The pto shaft is held in the housing by an external snap ring Once you get the snap ring out you can work
the housing off of the shaft and have clear access to the seal. While you have it apart inspect the pto
shaft where the seal rides on it. Some shafts have a sleeve pressed on for the seal to ride on. If that
sleeve is pitted or its a good idea to replace it or youll still have a leak. hope this helps

Funny thing, I just replaced the fluid when I had the cover off for lift problems. I was thinking of jacking the tractor or backing it up the trailer ramps to minimize fluid loss.
So all I will need is a seal and gasket if the shaft is good.

Drain it, I don't think you can tip it far enough to leave the fluid in. If it's like the 2000 the bearing housing is right at the lowest point of the rear end. If it has the seal sleeve on the shaft, it's a shrink fit on the shaft. You have to split the old one with a chisel to get it off. Putting the new one on, the trick is to get it hot enough (heat till it's yellow) and drop it on the shaft quick and push it down on to the bearing and hold till it cools some. It's thin so it cools quick. If it's not all the way on it will grab tight and you'll have to get another one. BTDT. Not expensive so it's not worth changing the seal without a new sleeve.

I was going to suggest parking it on a hill but didn't know all the parameters of your situation so I didn't.

Around here the only flat spot is my garage floor!

Yes, get the nose down, like on a hill, or raise the center housing on ramps to minimize or eliminate fluid loss. We used to do them on a loading ramp to save clean fluid.
