3408 HEUI engine..? Have fun....
Can't be bad, I see them with 40k hours all the time. Just had new injectors put in it .

The D9R is basically a good tractor. Our ones were given a life of 65k hours and by then the frame was getting to the point where it wasn't economic to repair any more. Bolt-on components can be changed ad infinitum so long as the frame holds up.
The problem IMO is with the engine. The 3400-Series HEUI was a bad design when it was first introduced in the mid-1990's (who ever came up with the idea of running a hydraulic system on dirty engine oil.?) and it hasn't improved much since, if at all. I had sleepless nights with 3412 HEUI engines in D10R's for a number of years and the only way they got completely fixed was when the D10T came out with a C27 in it. For any machine working in a 24/7 operation reliability is a critical factor, maybe not so much for a contractor machine that might only work 40-50 hours a week, by comparison our tractors clock close to 7k hours a year. A turd can be polished as much as anyone likes but at the end of the day it's still a turd.

The old Ford Powerstroke 7.3 seems to do pretty well. But we are talking different life cycles also. 7,000 hours on one of those is pretty much a lifetime. Maybe HEUI was better suited for something like that that doesn't run so much. They did not seem to have the troubles in our area as when the 3126/C7 came along. Those things had problems with every part. The 7.3 were extensively used in ambulances here and everybody remembers those days fondly, after that came the sick.0 and now it is a mishmash of all kinds of things. We didn't realize how good we had it back then.

Different animal Birken. The only thing that the Powerstroke engines and the 3400 Series have in common is the HEUI acronym after the engine model.............
We were tossing a set of injectors in our tractor HEUI engines about every 6 months on average.

My point is that on the smaller engines they still used filthy black engine oil as hydraulic fluid, and it seemed to work. So I wonder what about 3408 injectors they could not make work.

D9N is fitted with a mechanical injection 3408 engine. It is completely non-electronic and nothing like the 3408E HEUI engine fitted to the D9R.

If you don’t mind me asking what did you get it for?
I paid 49,500 with auction fees. Gotta do a little work to the blade face and replace the hydro cooler cell, it leaking otherthan that, it runs and works perfect.
6 hours of hot water washing on this side. Doesn't look to bad for the original look.
Thinking about possibly getting it tip top and flipping it and getting a 6r maybe .
What do you think it's worth brand new undercarriage and 5800 hours.

Is this the machine?
CAT D9R, Serial Number: 7TL01393
Enclosed Cab, Air Conditioner, Heater, 14’ Wide Semi-U Blade w/ Single Cylinder Tilt, Differential Steering, 30" Single Grouser Track Shoes, Counterweight
Price: USD $44,500
Auction: Thu, March 14, 2019
Condition: Used ROPS: Enclosed Iron Planet Ecorse, Michigan
Last time I ran numbers on a complete undercarriage for one of these it ran about $90,000. Auction and asking prices are all over the boards for these machines. It is a great core for rebuild but only a few places attempt them at this point in time. Fix the leaks, change fluids and filters, remove the pans and clean everything out and finally put a paint job on it. You could probably ask $150K and give your self a year or so with moderate marketing expenses.
You could also lease or rent it and get a continuing payment and probably make more. But then again you will have operational risks that go along with that type of income.

It sounds like you got a great buy! Maybe other bidders were worried about the engine problems?

So, am I the only one wondering why someone would spend the money on an undercarriage and then give it away at an auction??

Government agency?
Machine just went through full rebuild 5800 hours ago and it has a brand new undercarriage .
