YIKES!!!!!!

Well, I moved my recently aquired Super M out of the garage yesterday and parked it on a slight slope (front of the tractor lower than the rear) along my driveway. About four hours later I walked up to get it, and I noticed "RED" oil under the tractor on the grass and on the left tire and rim. I've now come to the conclusion that someone must have previously dumped some automotive "transmission fluid" in the SM transmission and differental, and it was thin enough to seep past the oil seal and leak out around the dust cover behind the "lift-all pump" while parked on the slope.

I'm wondering if the oil seal has been damaged by the automotive transmission fluid (no idea of how long it's been in there), or, if it will still hold 90# gear lube.

What do you folks think????

I'm certainly not looking forwards to replaceing the oil seal.

Thanks,
RoninKS

The landlord has a JD tractor [2630] which was sitting out in the sun at about 80 degrees after a cool morning of around 30 degrees. He found oil all over the scraper & tractor which had previously been clean. Turned out to be a hose blew out from pressure buildup due to the heat. Look around your tractor to see if anything like this could have happened.

By any chance is that tire loaded with beet juice and leaking ?? The tires on my compact diesel are loaded with beet juice. When there is beet juice on the ground it could look like ATF, don"t ask how I know.

Unlikely it built up enough pressure to spray or pop seals. The gear shift lever isn't sealed and will serve as a vent.
Open the check plug, a small, maybe half inch or so square head plug just above and forward of the clutch pedal. see if what comes out matches what you see on the groud. If the oil lever isn't high enough to run out on a slight forward slope (that whould be low) open the fill plug (inch and a half or so) in the deck sort of between the brake pedals and the gear shift. Stick a clean stick in to pull a little sample.
Good luck, Wm

Are you sure this wasn't an "outside" job with some prankster having come along and pouring some AFT on it? Sounds to me like that could have been the case.

I don't know why you would think an oil seal would be damaged by ATF. How you you think they keep that stuff in slushboxes.... with OIL SEALS!

As I mentioned, fluid was also sprayed on the rear tire and rim.
I can only guess that the sun shining on the tractor warmed things up and built up enough pressure to "spray" the fluid about 3 feet sideways past the dust cover.

It's difficult to tell from my IT book, but it looks to me as though the flange on the oil seal is towards the rear of the tractor,.... but if I'm looking at the picture wrong, and it is actually towards the front of the tractor, could pressure have possibly "unseated" the seal in some way?

I wasn't there to see it, but the ground and tire almost looked as though a small red-oil "bomb" had exploded. I wouldn't have thought too much about it "if" the wind had been blowing, but it wasn't.

I can't think of any other reason besides "heat" (from the sun) for such a leak, I had only driven the tractor about 100' from the garage when I parked it. This was the first time the tractor had been moved since I topped off the lube-level (2 days before) with 90# gear lube.

The temp here got up in the upper-80's the day this happened.

Anyway, I thought this was pretty weird and was wondering if you guys had some ideas. Due to my health, I'm not looking forwards to tearing into the transmission on this tractor just to check things out.

Thanks, RoninKS

Ron,
The precursor stocks that ATF are made from are more parafin based than the mineral oil that is common to motor oil and Gear lube. There may also be seal conditioners and ingredients in it not found in other oils. However it is not prone to causing seal deterioration in any drastic sense.
At about the same time (to keep the experiment controlled), take a sample of the "mess" oil and put it on clean printer paper. Next to its spot put samples of the other oils from the tractor. Watch for time to spread, color, and smell. If no match, not your oil! JimN

Fellas, I took the plug out and checked the oil level, it is down about 1/2". The oil in the transmission matchs the stuff on the ground and on the tire. All hoses are brand new, and the tires are "unloaded".

I guess I'll just wait for another warm day and drain the transmission and differential, then replace with new 90#.

I hope the same thing doesn't happen agin after I replace with new gear lube.

Thanks for all the ideas,
RoninKS
