If you have the PTO removed, perhaps you could take a photo of the end of the transmission shaft and post it.

Quick Links, top left of page, select the Cub Service Manual, section 6. Section 6 has a drawing of the transmission/differential including the PTO.

go here and go to drive train, and then look at transmission and at belt pulley-power take off.

Thinking the original poster is suggesting that the gap between the PTO shaft and the main transmission shaft is a shaft break.

Other things in the PTO/transmission will break before the PTO shaft or the main transmission shaft, such as the transmission gears or the PTO clutch.

Hi,
Please explain to us more of what work you have done to the Cub, if you have taken it apart.

Below are more pics from TM Tractor of the clutch shaft, the 1st pic shows the bearing that is tight on the shaft, it holds the shaft in position in the trans case.
The 2nd pic shows what the rear end of the shaft should look like, where the PTO shaft meets it. The flat shiny place is where it runs in the bearing that is in the trans case.

To remove the shaft, you have to split the Cub in front of the trans, and remove the shifter cover. There are 2 trans gears that are on the shaft, the small one can fall down in the trans, I think, as you pull the shaft out to the front.

You could remove the trans oil drain plug then and change the oil, and wash the trans out with solvent and a brush, if it is dirty inside.
The trans oil, and the 2 final drive gear case oils should all be checked, or changed, even if you don't take anything apart. They are 3 separate gear cases, with 3 separate oil levels to check.

That is what it looks like. I just bought the cub last month I needed a log splitter and it has one set up on the back they just put a pulley on the end of the PTO shaft to run the splitter hydraulic pump so yes when you take that PTO shaft out you can see the end of the shaft coming out of the trans is broke on the end it did have metal shavings still attached I was hoping there was a way to add a sleeve or something to extend the shaft far enough to reach the PTO to get me by until I can tear apart. I do not know how to post pics using my phone as I am away from my computer at the moment thank you for all the help and suggestions I am trying to learn as I go

Thanks, yeah that's the shaft in the top picture that is broke I just talk to parts manager at a case store and he said they don't manufacture that shaft any longer I did find a salvage yard by Pittsburgh that has one but I have to tear the whole transmission off to fix it the case manager I spoke to suggested welding it concluding the fact it's junk and is just short I may try that to get by . Yes I have taking the PTO off and would be able to see through the filler hole. I had found that manual that was suggested and it has been very helpful the motor was knocking but after changing spark plugs wires and the cap knocking stop I also run highest octane fuel and I believe that helps. I believe it's a pretty decent tractor all in all and just need some TLC I'm sure if I take care of it it will take care of me thanks for everything guys!

Thank you! I'm going to go ahead and try to weld it solid for now.

IMO, welding the shaft is not an option. Since you're going to have to split the tractor to remove the transmission, whichever option you choose, I would opt for a new shaft from TM Tractor Parts.

The seal and probably the bearing will also need replacement.

The way it looks to me, that shaft didn't break. The pilot bushing between it and the PTO shaft went out. Subsequent movement between the shafts chewed up the end of the shaft. I can't tell from the picture whether the hole in the end of the shaft (where the bushing belongs) has worn too far to hold a new bushing or not. The end of the splines on the shaft look good. If it will hold a bushing, the shaft is good. I assume the front end of the PTO shaft is also chewed up beyond use. If you can clean up the ends of both shafts and use a bushing with appropriately oversized OD and undersize ID, you might be able to save them. Otherwise, you probably need 2 new shafts.

Only the one shaft was damaged and the PTO shaft still seats in the end of the damaged shaft but the sliding clutch is JUST a little short. The pulley actually spins if there is no pressure that's how close it is that is how close it is
