to dam hot & humid to work on this today but had a thought and wanted an opinion on it.
If I use a grease zerk for the breather plug on the bottom side of the cylinder ... would it let too much air in and not allow it out fast enough? I think I'm gonna try this route unless someone can give me a good reason not to.

Take the fitting out and look in the hole, there is probably a retaining wire/spring on the end of the rod, pop it off the rod and then pull it out. Maybe

I like that "maybe" you put at the end. LOL
Not sure I'd have the ability to put the retainer back on, if it's there. I'm starting to think, easiest to try the homemade breather first. and if that doesn't work then investigate further before buying a new cylinder.

I had this idea in mind....... a brass wire breather plug or a mesh breather plug. The part I had in mind that would work is JD part #AE38448 or something similar. Tap a hole in your cylinder and clean out the shavings, then find a coupler that the breather can thread into. Weld the coupler to the cylinder so the breather doesn't protrude into the cyl bore and then leave the breather assy on the cylinder from there on out. If more oil needs to escape it can and the breather will keep crap from going in.

guru, I like how you think. No foreign objects intruding inward. Welding a coupler on the outside seems like an easy solution for a breather install. Just gotta keep the heat down enough to eliminate warping the tube -- maybe weld a bit, cool, and repeat, not like its gonna have any pressure on it and I suppose it wouldn't really matter if it had a pinhole -- it's supposed to leak air.
much appreciation to ya!

you're welcome Angus. Be sure to take a pic of the final product so you can send it to the geniuses at kuhn to show them how it shoulda been done in the first place.

Angus, I believe Rick is onto something. The marker cylinder on my jd 7000 series planter was like that. You took one of the fittings out to access the snap ring for lack of a better term. You push or pulled one way to access the ring and pull it out and did opposite to reinstall. Hope this isnt to confusing.

I would think there almost would have to be a breather of some sort, i cant belive there isnt, air has to b able to enter and exit as the cylynder strokes i would think. Usless there is sopossed to be a vacumm inside?

Hillbilly, after you and Rick are saying mostly the same thing, I'll look inside for anything resembling a retainer before I do any modifications. I've just been busier than a long tailed cat in a roomful of rocking chairs the past few days and haven't had either the need or the time to look at the tedder yet.
2+2, I agree that it's a wierd setup. Don't know but what the compressed air (when it's folded up) might be to help push the cylinder out when unfolding. This is the first one-way cylinder I've seen without a breather. I'm sorta puzzled at how they assembled the damned thing to begin with. Maybe when I actually get around to looking at it, I'll get an education along with some experience. ;D

Maybe when I actually get around to looking at it, I'll get an education along with some experience. ;D Angus I was going to reply pertaining to this thought..... after thinking about it, I bet the captive side does trap pressure to help kick the outer spinner wing down. Adding a breather might make it where it needs a push to get gravity to help bring the wing down. I looked at a new kuhn today and the wing cyl's have a small accumulator bulb on the deadside of the cylinder so help trap and release that pressure. I still think a bung to drain it would be a good idea, but you might have to install a plug so it can trap air pressure so it will unfold without being a PITA. jd

I have never ran across a cylinder that couldn't be taken apart, but then I haven't seen yours and I'm only a farmer with not near the experience of some on here. Keep lookin for a clue. Would it have a small rectangular slot in the side of the barrel at the top ?

Would it have a small rectangular slot in the side of the barrel at the top ? I agree 100% that there is the potential for this cylinder to be taken apart -- my uncertainty lies in my ability to get it back together in a useful form. ;D ;D ;D I've seen the slot which you're referring to on other cylinders, but not this one. It almost has to be like RickNCMD & the Hillbilly are talking about with some sort of internal keeper, which brings to light my limited abilities to put this sort of stuff back together once it's apart. That's a pretty small fitting hole to get the keeper out of, let alone put it back like it's supposed to be. At least for my tools and skill set. eta: I've been keeping busy the past few days anyway. Mowing and baling while the sun shines. 409 bales the past 2 days and prolly 175 more for tomorrow. Might end up being a pretty good week if you don't take into account the HOT temps. Would like to maybe finish the main part of haying by the end of the week, but will have to slow down a little to take it easy on my 69 yr. old rake man -- who insists on raking with a 4020 w/o a cab. Too much tech on the cab tractors, refuses to do much more than move one down the road.

Nah, they're probably right. It should only take a small screwdriver/pick to start the square wire-shaped keeper towards the port hole . . . So as you rotate the ram, it will feed itself right on out. Going back together will be even easier since you will have seen it come apart. If Rick & Hillbilly are right, you'll have one of those "Huh !" moments when you see how simple it is. Good Luck !

Can you get a picture of the ram end? I've rebuilt some pretty bizzare cylinders.

Can you get a picture of the ram end? I've rebuilt some pretty bizzare cylinders. here's a pic for ya. Prolly not even do any more to this the rest of this week, since the heat index is around 110 AND the forecast was just updated to include a chance of rain again for tomorrow night and thursday night. Might need to use this damned thing again before I get the cylinder fixed.
