PTO removal

I have been wanting to upgrade my PTO with a 1 3/8 shaft for a long time. But, after all the horror stories I've read on here about people trying to get them out, I just never tried it.

But now that I've removed my top cover to replace a bent control rod and the appropriate things like the piston and relief valve, I have decided to remove the pump and clean everything out good.

So I attempted to remove the PTO shaft this morning. I removed the four bolts and that thing slid out of there like it was just put in at the factory yesterday.

In the ten years I've been brush hogging it's seen a lot of hard use, especially when I first got the tractor and had to clear 30 years of brush growth. And the mower didn't have a stump jumper on it because I didn't know there was one available for it. I put that on like three years ago.

So anyway guys I posted this so if any of your are putting off updating your PTO shaft, they are not all horror stories

i replaced mine with a 1 3/8" shaft shortly after getting it. if i've ever done an easier mechanical job, i don't remember what it was.
 
I had one in my 1951 8N (Nellybelle) that had a slight twist in the splines when I removed it. I replaced it with a new 1 3/8" until I retired it. It now has a 1 1/8" to be able to have the original cap back on it.
 
Not uncommon.

Even an imperceptibly slight twist will prevent the PTO shaft from sliding out of the pump.

Thirty years ago, I had to torch off the PTO shaft both in front of and behind of the pump in order to remove the pump from my Fathers 51 so that I could drive the slightly twisted shaft out and install a new one.

It took quite a bit of heavy pounding with a 12 pound sledge on a hedge stump with a hole drilled in it for the shaft to remove the stub shaft but there was no damage to the pump.

My 52 8N was given to me with a twisted PTO shaft, the bushhog "somehow" ate 12' of chainlink fence . . .I tried everything including a come a long to pull that thing out, no go. Finally broke the tractor in half, chocked the wheels and tried the come a long again, still no go, took a 3 lb hammer and just tapped the end of the pto shaft inside the tractor and it popped out like a greased pig, slid the new one in and all is well.
 
Now, those are the kind of stories that always kept me from attempting to upgrade the shaft long ago. :wink:
 
Got the new shaft today. What surprised me was that it even came with the screw on PTO cover.
 
Mine came out nice and easy, too. I was replacing just the seal, not the shaft, but the shaft has to come out for that.

Bigger problem was getting the seal out to replace it, since I wasn't at home with all my tools. The seal pullers I brought with me weren't the right ones. But I managed. (Didn't change out the sleeve, though, even though I had bought a new one.)

"What surprised me was that it even came with the screw on PTO cover."

mine did too. good thing, since the new shaft i got sticks out farther than the old one.
