D4 5t

Seems like you already have it figured out.....make one good one out of the two.
Your choice of which one but the narrow gage that already has the blade would probably be the most useful. All the parts are interchangeable between these two models as well as most parts on the 7J and 2T models. J model D2's will have some interchangeable pony motor parts as well. Try advertising in the classified section here for parts you need. Good luck with your project and welcome😊 😊

dratt,

Depending on where you live, there are a number of scrapping/ dismantling yards around the country. I'd be checking with the nearest one for the parts you need, plus on the BB here. One of us might live close to you, and quite a few of us have parts for trade or sale.

Just an idea. .good luck and have fun with the restoration of whichever one you decide on. Keep us posted. .

Thanks for the heads up.
I live in Necedah, Wisconsin. (54646)
Both machines are in Alma center Wi. as of right now. I need to move them to Necedah when it warms up. I am guessing these machines to weight 11,000 each. I am hoping to move them with a trailer that has two 7,000 lbs axels on it. One at a time of course. I am trying to do as much research on these as I can before I tear into it.
I will post some photos of this as I go along. You will be able to see the whole thing come together. (I hope 😊 )
Does anyone have any books, blue prints, parts manuals for these machines? It would be best for me if it was in a .pdf format or an online file that I could review.
I agree with old magnet on which one to restore. (Narrow gauge D4) this one ran last and has the blade.
Something that is a bit confusing to me was that the direct electric start they were installing was being mounted on the operators side of the clutch housing. The information that I see for doing this shows to mount it on the other side.
Any suggestions on the first thing you should do with these when starting this project? (like precautions) or when we first go to move them?

I am getting closer to moving the 2 D4 dozers to thier new home. I am looking for information on where to get service manuals, parts books, operator instructions ect...
I am green as they come when it comes to these dozers. I have never worked on one or even driven one.

I have been watching pasochis and his project and am inspired by his determination on the D8!!
It will be awhile before the D4's come home as the wind chills here in Wisconsin were at -65 this morning

I'm a little confused on the wide gauge - narrow gauge. The 5T is the wide gauge and isn't the 2T the narrow Gauge. My narrow gauge D4 has different S/N's, the Rear S/N is a 2T corresponding to the narrow gauge and the engine S/N is a newer 5T. One different between the original 2T engine and the 5T engine I have is the hood over the engine is about 4 inches longer, I have been told most the lenght difference is in the radiator brackets?

For my work the narrow gauge is peaches and cream. Clay

Both 2T and 5T came in standard and wide gauge versions. Wide gauge is identified by a W at the end of the serial number. Seperate serial number series for standard and wide gauge D4 did not start until the U series, 6u being standard and 7U wide.

OCB,
Don't know about that hood😕
I show 7J3332 - 7J9999, 2T1 - 2T9999 and 5T1 - up as using the same (standard tractor) hood #7B5348.

OM, the parts book shows up to 7J3331 a 3B7800 hood and then on up shows a 7B5348 but by the picture only it shows a small cover on the top right rear section of the early hood where the later one is blank so maybe they both would fit I don,t know. The orchard models show different hoods yet.
