John Deere 3020 239T Engine Swap

The kinda sorta before photo, I forgot to take pictures before I started tearing into it. Yes, those are IH weights, I guess they used what they had.



4030 adapter plate in place.

 
Engine installed with front pump mount off 4030.



Mocked up with hood and other sheet metal on. So far this is as far as I got, no time since the plants started growing.

 
cobroller, your eyes do not deceive you, that fan is a pusher, the pump sits too high anyway, so I need to find a different one.

Jim,
It's hard to see in the picture, but there is a plate at the back of the frame rails bolted to the adapter and welded to the frame. For the front ones there is a spacer welded in. I did have to mill out a little bit of the bottom of the frame rail where it hits the pump support.
 
Anything off a 410 backhoe, 2030, 2440, ect... that has the ports for the oil cooler. That engine is out of a street sweeper, had a 4 speed trans behind it on an SAE bell housing.
 
2520 uses the same pump that the tractors I listed do. I just need to get one and the thermostat/outlet housing too.
 
Update: I have successfully solved the flywheel issue.





I had to machine a custom spacer to move the bolt surface back a half an inch (the difference between the crank surface plane from the orginal engine to the replacement) and convert the crank from piloting on the OD to pilot on the hub and hold the pilot bearing. The flywheel bolt holes were machined to mate with the 239's pattern, not even half a hole, the center of the flywheel was machined to mate with the adapters hub and sent off to get balanced and surfaced. A stiffener plated was also fabricated to spread the clamped load around the bolt pattern.

The clutch was then installed and adjusted like any 3020.
 
Here's an update for everyone following.


Here's the water pump and thermostat housing installed. Standard water pump for a 2510 as well as many other models, backplate is 2510, thermostat housing is 2510, but is used on many other models.


I ended up having to use a hydraulic pump drive off a 4230 I have sitting to clear the bottom of the radiator.


Onto the next challenge, in the next post and series of pictures I'll show how I adapted the exhaust manifold.
 
Ok, onto the turbocharger challenge, if this was a side console tractor or had single hydraulics I wouldn't have to do this, but alas this is not the case.


I took a manifold that had a 45 degree exhaust outlet, cut it squared with the manifold, fabricated a plate to bolt the turbo charger to and keep it under the hood. The extra real estate is in case I have to bolt an exhaust elbow to get out the hood.


These pieces are the front pieces that channel the exhaust up through the top plate's opening.


Welding the pieces together, 1/8" diameter MG210 welding rod was used to attach the mild steel plates to the cast manifold. Prior to welding the pieces were preheated in an oven, welds were peened between passes to relieve stress. The cover plate was welding to the mild steel pieces using 7018. After welding the manifold was placed back into the oven to normalize and begin a slow cooldown.


Manifold on the engine, TO4B off a 4430 for mockup, there isn't enough room for the intake hookup with the dual hydraulics, but the GT turbo in the next picture has enough room.




This is a GT28 off a 4.4L JCB engine, I'm using it because I have it and it should work really well. There's enough room to get a cobra head type rubber hose to hook up the air cleaner. The next challenge will be getting the oil drain hooked up, fabricating the tubing around the manifold and drilling and tapping the oil pan.
 
For those that are anxiously awaiting an update. It is finally alive, I drove it to my dads shop across the street, aside from a few small leaks, everything works as it should, trans sounds good and shifts even better so it looks like it's worth finishing. I have a question for the masses, keep the factory wide front and set it narrower or swap it for a roll a matic? Dad wants to keep the wide front, I'm still undecided about it.

My email is open so you could also send me pictures to my email. I am very interested in this build.
