Amateur Hour: TO-30 splitting

[FergusonTO20]

Hmm... the leak is so bad that it leaves a trail of closely spaced oil drops when it is in motion. The thing is, we replaced the oil seal on the engine side of the clutch section, and we are absolutely certain that we got it in correctly. For the moment, our best guess is that we somehow overfilled either the engine or the transmission. For now, the TO-30 is parked under a tarp. I'm hoping to find somebody who'll be willing to put it to good use. But for now, I have lots of winterizing tasks on my hands.

, one last detail that I expect will trigger some hilarity. I hold a master of science degree in physics, and I have been part of a NASA airborne scientific mission -- but I couldn't repair a tractor. So much for fancy degrees.

Don't feel bad
I was once called out by an nasa electronics engineer an a master electrician to diagnose an exaust fan running backwards.
I climbed the ladder to take a look
Asked them if I was being pranked
"Ummm no why?"
So i swapped the correct wires to reverse the rotation an climbed down
They had been trying to figure it out for hours.
Unit was brand new with a very legible wiring diagram in plane sight


We dont know what we dont know lol

If you drained all the sumps, tranny/diffy should take 6-gallons.

Unsure if there is a vent hole up high on transmission that would leak inside housing if way overfilled?

You could drain into a couple clean buckets and see what volume comes out .

Yes, my manuals said 6 gallons for the transmission, but this time we put the hydraulic oil in slowly. We started with just three gallons, then added another gallon when the dipstick showed nothing. I don't recall where we stopped, but it was just a bit less than 5 gallons, even though we had drained the transmission completely. We had a similar experience with the engine. We're hoping that, if the tractor stops leaking oil after some point, it will be fine, indicating that somehow it needs less oil.

There may be oil in the hydraulics that accounts for the other gallon. Not sure if lifting the 3-pt arms by hand a few times would drain that?

Good point. I'll give it a try.

I was asked to investigate a bad oil leak, after the owner had in his words "done an engine overhaul"still had the oil leak. After removing the flywheel....I noticed, the metal insert that was installed on the end of the engine block,that aligned with the CAMSHAFT bearing bore.BAD OIL LEAK....
Bob...

I think you nailed it. As a retired design engineer I agree with the previous comments of "har, har, har". I have no idea why anyone would design such a thin (0.071) flange begging to be sheared off. Luckily my ring gear seems properlly located, tight and true so I won't replace the flywheel.

I'm sorry I caught this thread at the end of your adventure in pain because I did that split for the sole reason the transmission end of the main shaft seal had failed and the hydraulic fluid was fouling out the starter. If you did NOT replace that seal and continue to run the tractor you may be having to replace your starter as well. Not for nuttin I replaced my clutch while I was in there and dont remember having to use a special tool to align...jus sayin
