John Deere 4039T swap into a pickup truck....

Hello All,
I am a new member in North FL. I'd like to to find out if anyone here had done a similar engine swap with this oil burner.

I have acquired a John Deere 4 cylinder 4039T diesel engine from a government surplus generator. It seems to be similar in size and weight to a Cummins BT4.

Has anyone here put on of these 4039T into a 1/2 ton pickup? I was leaning towards a Ram 1500, however a Ford F150, Chevy or Toyota Tundra would certainly be a potential receiver of this motor.

It's only around 100HP so I can't see installing it into a 3/4 ton truck.

Anyone interested in providing some info or suggestions? I am all ears and really appreciate your feedback.

Thanks in advance,
Dale

I remember seeing a guy on youtube that was doing some swaps with john deere engines. I believe he was claiming some pretty high mileage numbers but did not really show any under hood shots.

I would suspect the major headache would be tying the engine and transmission together.

I am not sure how the injection pump is set up but I have also heard some of those industrial applications were more for constant RPM. They are not set up for constant up and down that you get with driving in traffic.

The IP will be a stanadyne. , but being from a genset will be governed to 1800 rpm. You will likely need to have an injection shop modify the pump for variable speed operation and raising the governor. You probably won’t want to spin it more than 2400-2500 rpm though.

As far as transmissions go, it should have a standard SAE type bell housing pattern. Lookup “SAE bell housing dimensions” , grab a tape measure and figure out what size you have. From there you can start looking for transmissions and or adapters. For direct bolt on transmissions you are going to be looking at something out of a medium duty truck. They will be big and heavy. Otherwise there are several companies that make SAE to automotive type adapters, just google it. Going that route would probably net you the most streetable ride. Just try to keep in mind the narrow RPM range as you plan out this project.

Could be wrong, appears to be a typical db2/4 design pump, so I'm sure it can be modded.
Looks like some were rated to 2500 rpm.

Man I was thinking the other day… how cool it would be to put a 6068t in a pickup. 6.8 liters vs the Cummins 6.7. I think it could be fit in a superduty or an obs ford fairly easily. Find a pump shop to get an injection pump built for 175-200cc and make 350 crank horsepower pretty reliably. You see them all the time with 10-15 k hours all the time. In a pickup (not being ran wot all the time) I bet it would be dead nuts reliable. I mean the bottom end is as stout as they come.
A DT 360 would also be cool but you get more displacement with the John Deere 6068 and they are about the same size.
47.4 inches from bell housing to front of the fan, 23 inches wide and 38.7 tall. I think it could be done and it would be super unique. We have a John Deere dealer right up the road from the house so parts availability would be a nonissue.
Tell me what you think??
