Leaking SUDT out mid PTO...BX2660

amg280 - I'm the OP of the other thread that Chris and EE Bota referred to. If you figure out how the vent (called breather in the parts manual) works, please post back so I know. If I figure it out first, I'll post back here.

I'm really suprised that no one has posted on how it actually works or how it's removed to be checked. It appears to be the same part number for many different models of tractors and RTV's.

Here is a link to the thread.
BX24 HST Dip Stick Blew Out - Page 3 - TractorByNet.com

I just tried to offer advice to make up for my bum advice to Thavil. I think the vent can be tested by making it do its job...vent! It vents based on changes in temperature but MOSTLY based on cylinders being extended (a vacuum) or retracted (a pressure)
A man ought to be able to raise the boom and the 3pt, pull then replace the dipstick, then lower all quickly....and there will be a pressure if the vent is clogged.

A man could pull the stick...understand how hard that is. Raise the boom, curl down the bucket, raise the 3pt, then repull the dipstick. Was it harder to pull due to vacuum? Replace the stick. Lower and uncurl everything...repull the stick. Was it easier to pull due to pressure?

Well I finally got around to putting the new rear mid pto seal in last night. It was very easy. The old one looked fine. Tractor leaves spots everywhere I park it. I ran it till the fluid got warm last night and then parked it in a dry spot in my barn. When I checked it this morning, to my dismay, there was another little puddle right under the mid pto shaft :(.

Im not sure if I didnt clean it properly from the fluid spewing from the change, or what, but it really upset me. Im going to get some cans of brake clean and really make it spotless underthere, and then run it for a bit and see what we got. I really hope it fixed it but it doesnt look good. Now that mean it has to go to the dealer and they will probably have it for another month :(.

Cant kubota give me a lawn mower or something while mine is in the shop? It only has 160 hours on it. My lawn grows like wildfire. Im going to have to buy goats.

When you changed out the seal what shape was the shaft in? Sometimes they get worn and the seal can't apply enough pressure to it. If you have a bearing store they should be able to set you up with a fix if the shaft is the problem. I think they are called Speedy Sleeves (or something like that). A simple thin sheet metal ring (looks like a top hat) that slides onto the shaft and creates a new sealing surface.

You know, if you decide to send it to the dealer, ask them if they have a used mower of some sort you can use to mow until yours is returned. Since it did not take you long, it likely would not take them long either. Either way, they should be more than willing to either be fast, or loan.

I had a similar thing with my front hubs. I did a repair in the area that rotates during steering, but still got leaks. I was bummed. I thought I did a great job, but I didn't like the sealant I used for the hubs. It was a brown and smelly permatex sealant, but the book called for Tri-bond 1234, and there is no such thing made, as best I could tell.

I took wipes and cleaned very well where I hoped the leaks were coming from, the sealant area, not the seals. Then as a final check, I took a shop paper towel, and made sure I could not pick up oil.

Next, I drove it all around to get the front axle oil hot, and then I checked the area again with a clean paper towel. I did not wipe, I only pressed the towel firmly against different areas, and examined the towel for wetness. Much to my relief, it was leaking exactly where I thought. New and better sealant was needed on the hubs, I did not have to replace the seals over again.

Try that method perhaps. I worked for me.

As a final check, I checked the transmission section of my tractor manual, which is similar to yours, to see if there is anything that would be easy to miss. I saw nothing obvious. It did not explicitly mention the PTO shaft seal replacement, but for the axle seal replacement, it said put a little grease on the rubber seal lip, but do not put anything on the outer circumference, keep it clean, and the tractor mating surface clean.

I wish you the best of luck. It very well could be residual oil, and that is frequently the case. I would not be in a big hurry to mess with it, since sometimes, but I admit, rarely, a new seal will have a slight imperfection that will quickly wear away, leaving a good seal.

Are you sure its not the tranny filter? make sure its tight. It would leak in the same spot on floor as MMM pto shaft. You could have a bad gasket on the filter.

Or maybe grease from the PTO shaft? I removed the SUDT from my mmm and installed Amsoil's best gear fluid. The deck is removed in the fall, stored vertical and no leaks. No messing with the belt etc. This is odd.

Well I found the leak! Its not coming from the Mid PTO, but from where the casing bolts to the tranny. Look at my crude diagram. Sorry im not good with photoshop. After hours of brake clean and driving, and sitting, etc. Had a friend come over with a sharp eye. We both got under there with a high powered light and inspected. Its leaking through the casing seal, well one of them. Please see pic. Is this a big job?

p.s. will try to attach pic in next post having a problem...

Thanks for the follow-up picture, the discussion and the responses. I don't have this problem, but who knows about tomorrow?

I don't know how big a job it will be, since I don't know anything other than what I see in the picture.

I wonder if there is something that could be painted on to seal the area without taking things apart. The miracle of modern chemistry sure would be handy about now.
