Ford 4000 Gas, Change To Diesel

KCTractors,
Please help others help you. Describe this tractor better.
There are 2 models of Ford 4000. Early 4 Cyl red tiger engine. Later 3 Cyl.
There were also changes in the 3 cyl model over the years.

More info Please!
 
There are changes to be made... fuel lines, throttle rods, etc., etc., but it can be done. A 172 4-cylinder diesel is a bolt-in replacement for a 172 4-cylinder gas, and a 201 3-cylinder diesel is a bolt-in replacement for a 192 or 201 3-cylinder gas.
 
As others have said a 3 cylinder diesel engine will bolt right up to the transmission and front bolster, so no fears on that, but you will also have to source a diesel fuel tank, as the gasoline tanks don't have the fitting on the filler neck for the return line that the diesels have, plus you'll have to add the fuel filters, fuel lines, reroute the air intake line from the air filter, or replace the dry air filter with an oil bath type and then cut a hole in the panel above the radiator. Probably a number of small things I missed as well.
 
Starter and ring gear are different too.
As is the battery tray.
This has been discussed here before.
If i were to do it I would do a little measuring.
Use the intake manifold from the gasser. Block off the water inlets and outlets in it.
Use the diesel thermostat housing.
Then...
Cut the bottom of the gas intake manifold off where the carb bolts on and weld on a close elbow there.
Then I 'think' you might get by using the gas air filter. You would also have to modify the air tube from the air filter to the manifold. You might have to move the diesel fuel filter too.
It would be easy enough to solder a small fitting on the gas tank for the return line.
I think it could be done that way easier than welding the brackets into the nose for the deisel air filter.
 
If mine, I would rebuild the gasoline engine or find a diesel donor tractor and swap everything needed.

Real life experience putting a 1983 201D in a 1970 4000 gasser. Some of this has been covered, some is different than other's ideas.
Use the diesel intake, ring gear, starter. Use the original flywheel, or one from a Diesel tractor having the same transmission as yours. I kept the dry element air cleaner in its original position and custom plumbed to the diesel intake.
Modified the gas battery tray to accept a BCI Group 65 battery. Install a Diesel key switch and run a dedicated wire from it to the thermostart unit. Rremove the start relay and wire the NSS directly to the diesel start solenoid. Drill a hole in the fuel tank neck, gun drill a 1/4"x 1-1/2 bolt with the head cut off, install 'nipple' in the filler neck using two jam nuts, one in and one out. Connect diesel return tube. Replace choke cable with a properly marked fuel shutoff cable.

Did this a few years back, that's all I recall right now.
 
Fuel filter and lines, throttle linkage, yeah those, too. Add a diesel upper radiator hose.
 

I converted my 69 4000 from gas to diesel many years ago, I did have a complete diesel fuel system, head and most of the air filtration system before I started.
I drilled a hole in the gas tank neck and soldered in a tube for the return line.
It was easier to convert the engine than it was to convert the tractor chassis.
Lots of small differences between a gas and diesel chassis
A 4000SU uses the smaller 3000 fuel tank if you decide to change it.
 
The deal fell through, I bought the tractor over the phone, he said I couldn't pic it up till today (Saturday). It was mine. I got the trailer and truck ready for a 350 mile round trip. I called him to till that I was ready to leave, like he wanted me to do so he could meet me at his property. He tells me he sold it to a friend. This is the third time this happened to me. One time I went 175 miles to pick one up and I waited and waited, nobody around, no tractor around, nobody would answer his cell phone, finally a neighbor come over and asked me what I was after, he started laughing and said that he sold it yesterday. Boy, was I p---ed!
