Stuck PTO shaft

old · Aug 27, 2018

So I have this 3 sided PTO shaft that is stuck and it is stuck real good. Tried to get it to move yesterday by hooking it up to the loader bucket and then rolling to bucket out so it pulled on each end of the shaft. All I did was bend the top of the bucket which I have been needing to do any how. Tried heating it up just a little bit ago but I only have cutting tips so not sure I can get it hot enough. Was going to heat it yesterday but found out I was out of Oxygen due to forgetting to shut the tanks off one time. Thinking about hooking it up to the draw bar of the Allis C and pulling the other end with the 3 ton chain hoist and let it hang that way. I'm planning to barrow a rose bud tip Wednesday but figure it will not hurt a thing to put a load on it for a few days who knows maybe it will free up.

I know you have been soaking it real good with atf/acetone or some such.
Maybe, if you have one, rattle the female sides with an air chisel.

Probably has what amounts to a slight but permanent twist to it. Good luck but probably going to have to replace it.

Old is a post hole digger a 3 or 4 sided shaft?

I have a shaft that had a bad U joints and I just bought a new shaft for PHD. Old shaft is in garage.

I don't remember how many sides it has.

I think if you put a good pull on it, and hit it with a large hammer, being careful not to dent it. I had one stuck one time, and found the shaft to be twisted, causing a jam. I managed to brake a 4 ft pipe wrench jaw trying to untwist it. Just be careful. Stan

Last one I has stuck I chained it to my loader beside and parallel to a lift cylinder. Came right apart, if a loader lift cylinder won't unstick it I would throw it away and get a new one.

All that stuff, if they are a long class 6 or 8 they don?t like to come apart.

Buy a new one.

I'm with the others,,it's got a twist in it and it won't ever be right so skip the idea of yanking it apart and replace it..when or if it comes apart under a hard pull it will become a missile...and could take your head off at the shoulders...

I bought an old auger a few years ago and had the same thing. I hooked it between 2 trees with nylon rope and a come-a-long, I like to use rope because it has stretch to it. I put about a ton of tension on it and started heating and tapping, pretty soon it popped apart!

If it is an old one likely to be square if newer triangle. I have the Allis C hanging on it right now. May pull the C out and bring in the Ford 841S since I need to work on it any how and hang the ford up and see if it will pop it free

To start with I know better then to get in line with something like that while having pressure on it not my first rodeo and have done many of these but this one so far has been the worst one yet. Have an Allis C hanging on it right now and think I'll switch to the ford since I need to work on it any how. I hate to let something beat me

How about a little back ground? Is it something that you were using and you just noticed that it was not sliding? Or is it something that has been out in the weeds in the weather for five years?

Triangular shafting is Bondioli&Pavesi, or reverse engineered copy thereof. Genuine Bondioli has the shafting PINNED into the yokes, Comer and others weld the shafts to the yoke. The lemon shaped stuff is Walterscheid. Those European shafts have tighter tolerances than the old US stuff, antiseize and Moly grease are your friend. Lots of heat over a wide area, do you have one of the old gasoline blow torches around?

All I know about it was it was given to me as is. Now that I have a finish mower rebuilt and on the Allis C I need a longer shaft and have this one so figured I would try to free it up When I fist got it I would put ATF on it once in a while and it has sat In the shop for I do not know how long. It has all the right sizes to work just need to free it up.

Not sure what you mean by lemon shaped but this it is the triangle sort of with the humps at the points of the triangle. I have no ide how much is stuck in but looks like it could be 2-3 foot. Been thinking about trying the press and press it closed a bit more then try to pull it out again. I figure at this point I have nothing to loose. Have the rear end of the Allis C hanging up on it right now with the finish mower I need to shaft for on it also. Rear tires are 4 or so inch off the ground

way back in the olden days when i worked for the township highway dept, we used to straighten the cutting edge on the loader buckets. dug a shallow trench and started a charcoal fire. when you got a good bed of coals, we heated the bucket edge in there. worked like a home made forge. you can get some air on it to get the heat up. we used some water pipe, half or 3/4 with some holes drilled in it . lay that down first before starting the fire. its kind of cave man, but it works in a pinch.

Old, I have done it,hook it between two tractors pull it tight, then hit the shaft with a good 2# hammer. The last one I did came out like it was shot out from a gun.

Danny Prosser · Aug 28, 2018

Mr. Old I had one like that that stuck. I put it in a big vise so I could spray penetrating oil in the tube where it would seep down into it. I did that everyday and hit the yoke that was hanging next to the floor with a 5lb sledge. After a couple of days it started moving. After that ordeal I put a little grease on mine every year.

That's a good one Glennster - I'm gonna remember that idea. I've seen times when that trick would have helped me out. I'll bet a leaf blower plumbed into a pipe like that would really make a hot fire.
