PTO engagement

[staninlowerAL]

Here a post by Dale Finch where a drill bit was used to make a replacement pin:

There have been others as I recall. Good Luck.

Thanks very interesting

Yes it looks somewhat like that as best as I can tell. How do I change that?
Thanks

The assembly can be purchased from TM or Hamilton Bob's, both site sponsors, or attempt the "drill bit repair" that was noted.
To remove, with the PTO shaft out and the PTO guide removed, it's pretty straight forward. Push the PTO engagement lever down, remove the key at the bottom of the rod. Slide the shifter rod out, remove the collar and the assembly will slide out the inside of the transmission case. You will be able to inspect all potential culprits now.

Good luck,

And while you're in there, be sure to inspect the PTO pilot bushing, it can cause you a lot of the same grief.

Thank everyone started to remove the PTO yesterday, will finish this weekend and see what all needs to be done.
Thanks again
What a great site and people!!!!!!

The collar/"clutch" that you are joining two shafts with when engaging the p.t.o. , means the shafts need to be aligned straight and level.
you already know the splines need to line up , thus the slight release of the transmissions clutch to turn it's shaft sometimes.

Wear (?) means with my belly mounted brush hog I sometimes have to lower it completely to take tension off somewhere to make it easier to engage the p.t.o..
Maybe the belt tension on p.t.o. pulley pulling the rear of the shaft downward. And that is after the p.t.o. shaft has been out and serviced before.

Well look what I found
Thanks everyone

P.S Don McCombs I even figured out on posting pictures lol

I think that’s what we all were expecting that you’d find. Congrats on the photo posting.

Make sure you check the other things, though, because one of the other possible problems caused that shifter to move such that the pin was rubbing the edge of the clutch channel.

I suggest you go ahead and disassemble the PTO, replace the seal, remove the grease cover over the bearing, clean and check the bearing. Determine if you have the staked bearing, and if there is any movement of it away from the rear shoulder on the shaft. If there is, reseat it & try restaking it.

If the bearing is completely seated, make sure it is good, regrease it, check the grease zerk fitting is still there (push-in type), and reassemble.

The clutch set screw needs to be tight enough to keep it in that cutaway slot on the shaft, but loose enough to allow it to slide.

Hi,
Below is a listing at TM Tractor for a new PTO shifter shaft, you can look at the pics.
The lower pin in the pics is round.

If the splines on the end of the clutch shaft, or the splines in the PTO clutch (the round part that slides on the PTO shaft), are damaged, the parts may need replacing.

Below are pics from TM Tractor.
The 1st pic shows the bearing has to be on the shaft as far as it goes, the shaft is bigger to the left of the bearing, than on the right of the bearing.
The 2nd pic shows the staking used on the older shafts to hold the bearing in position. There are 3 stakes equally spaced around the shaft.

If the shaft has moved to the rear, it can cause too much space between the clutch shaft, and the PTO shaft, and the PTO can slip out of engaged.

Below is a listing for a new PTO pilot bushing, it goes in the rear end of the clutch shaft.

Below is TM Tractor's page of PTO parts.

If you take the PTO apart and replace the seal, clean the old grease out of the PTO seal retainer, and when you put it together again, I grease it through the grease fitting, before putting the unit in the transmission, then I can see grease come out at the bearing.
It takes some grease to fill the area.
The new PTO seals are usually thinner than the original seals were.
The seal lip has to face ahead, drive the seal in until it is flush with the outside of the retainer.
Don't hammer directly on a new oil seal, put clean, flat metal on it to hammer on.
Oil the seal rubber, and shaft where the seal runs before putting the shaft into the new seal.

Sometimes to get the PTO out or in again, I have to remove the bolt on the corner of the transmission that holds the PTO shifter guide, for the PTO lever, so the lever can go farther ahead. Then the pin on the shifter shaft can go to the rear farther.

Thanks

Okay I've been studying my cub service manual and looks to me that the PTO shifter rod lever inside is facing down, in other words pin inside is towards the bottom of the case and not up. Is this correct or am I reading it wrong, if it's facing up it may not let the coupler move ahead far enough. I installed a new shifter lever and I am still having the problem I also have a new shifter clutch to install now, but I found in the manual that I may have the level 90deg off.

Thanks everyone for your more than generous support given me on the PTO
I have replaced the shift rod and collar and it now works as it should.
Again thanks everyone, this is one nice information place with kind and understanding people.
