1800 pto shaft.

Ohio88 · Dec 7, 2016

A friend has a 1800 with the PTO shaft 10 inches out. It will not come further. We
have turned and pulled for hours. I know it should eventually come out. My concern is
I think they have tried to force it and may have bunged up the ends of the splines. I
have not talked to the person who worked on it before. Two questions. Is 10 inches
about where the splinters get hung up? And is there a procedure to remove a bad shaft?

When I pulled the long PTO shaft out of my 2-105 it would only come out about 10 inches then no further. I had a ready rod threaded into the end of the shaft and used a slide hammer but no luck. Someone had mentioned, lock two nuts together on the end of the ready rod and use an impact wrench to jar the shaft so the splines would line up so it could be removed. I tried this and it worked almost at once. Seemed that some of the PTO gears weren't aligned for the splined shaft to slip through and just pulling or turning by hand wouldn't work. There is an O-Ring that had to be removed before trying to pull the shaft as well. Just inside the cast housing several inches behind the cover plate.

Hope no damage has occurred to the splines on the one you are working on. It is a pretty hard shaft so I would think it would take a lot to damage it but who knows. It's also not a cheap shaft if you have to replace it.

Hope this idea helps you out.

Good luck!

Wow! Did you remove the O-ring once you had the plug out. In the 50 series you have 2 sets of splines, in the 1800 you don't have that.

Yes John, On my 2-105 I removed the cover plate, (2 bolts) pulled the plug using the 1/2 inch threaded rod and then using a small hooked pick removed the O-Ring as the book indicated.

I then threaded the rod into the long shaft, but found the shaft would only come out about 10 inches or so. So after trying with a slide hammer on the rod (not too severely) as I didn't want to damage anything, I tried the impact method as outlined and it slipped right out. Before that, I turned and pulled the shaft without success by hand.

I am not familiar with other models such as the 1800 series but thought perhaps this might be worth a suggestion. From your comments it sounds like it should be an easier one to pull with only one set of splines.

Naturally you wouldn't spin it round and round to damage the shaft or gears but the vibration seemed to help in my case, as someone else had suggested it might.

Sounds like he is having a tough time to get it out. Hope something works for him.

Of all of them I've pulled,I never had to use an impact. Not saying for a minute not to or that it's wrong,but just using a 3/4 inch wrench while pulling against one was as extreme as I ever had to get with it.
I did have to use a slide hammer one time though when the splines that go in the hub in the flywheel were all bunged up.
