Oil & Fuel YM2500 Pushing Coolant Out the Radiator

Well that number doesn't match anything.

Yes, it does. The number on the transmission.

Per the Fredricks UTDA agreement with Yanmar, they serialize the tractors on an ID plate riveted to the hood. I see the auction had S/N 2642. Are you saying you now own 2642 then.

Here is mine, 3661
View attachment 3830059

I now wonder even more. Your machine has a lower S/N than mine. Did Fredricks do a buy back or help a customer trade up to another machine and took the YM2500 as a trade-in?

So much speculation on this S/N 2642 . . .

2,642 is the Hours on the hour meter of the tractor at the time of the auction, not the tractor’s Serial Number.

Here is a better picture of the numbers on the Transmission, and the Serial Number used in the auction on TractorHouse, which is an exact match of 02864.

The UTDA “Fredricks Importing” Tag Serial Number attached to the hood is 4465, but is difficult to see in the picture.

I wouldn't have described the black smoke as soot, but that's me. The engine sounds a trifle uneven to me, but it picked right up when the throttle was tapped. In my experience, one, two, and three cylinder engines are never going to be as smooth or even as a four cylinder, much less an older engine vs one that has been through noise and vibration analysis with counter rotating balance shafts. I will admit to a soft spot for the old Lister one cylinder lug-lug diesels, but yes, they worked best when bolted to the continent, or a large boat.eah

I think that it is hard to armchair quarterback things from a distance. I am impressed at what Frederick's is doing for you.

All the best,

Peter

Yeah - tractor idling for goodness knows how long, then throttle blipped & a puff of black smoke is pretty normal I'd say. Try that with the average Lister & you'd be coughing for a week!

***UPDATE 07-29-2025 Tuesday***
Positive News!

I received a text from my local tractor mechanic yesterday. He got the cylinder head back from the machine shop yesterday.

I asked what they told him about it and he stated, “It took a light pass to clean up 3 to 5 thousand.”

I asked him if that was good or bad and he stated, “Good”.
He has everything he needs now to put the Engine back together and everything needed to repair the Throttle Shaft Assembly.

It’ll probably be sometime next week before I’ll be able to pickup the tractor.
