400/2510/2020 & 2520? & maybe others?

So a few years ago i bought a little 400 industrial with a FEL, gasser. i got it cheap enough, but never really messed with it. Now i am in a spot that a small little mower tractor like that would be great. So i thought, why not put a diesel in it?

So what i am finding is JD says that the 400 and 2020 have the same 3.3L/202 ci engine, and that a 2020 & 2510 have the same engine, The cross search didnt seem to work out well for me, but does the 2520 have the same engine?

It also showed no other applications that the 202/3.3L went in, but i also dont know the lineage of the 202/3.3L. Is there another engine that could bolt in?

This is becoming a "i hope to have it done by spring" project, so i have time to hit junk yards and what not. Just trying to get a better idea of what i machines i need to look for.

Thanks!

Any 4 cylinders will fit from 1965 until now, except 3020.

really?? that seems WAY to easy....what are you not telling me? HAHAH

Ditto any JD 4 cyl engines built '65 & after will fit your model 400

so i am coming up with:

3.3L
3.6L
3.9L
4.5L

that seems like a wide range of power plants and there shouldnt be a lot of trouble putting one in huh? This may work out better than i think!

If you have any other suggestions throw them out there, but thanks fellas!

You might have to switch front and rear housings.

The JD guys will get this straight if I mess it up.
2510 had 180 gas, 202 diesel. 2520 had 202 gas, 219 diesel.
Many utility tractors, dozers, log skidders, and other manufacturers used a version of that engine series.

A good running low hour diesel will run you $1500-$3500 depending on hours/condition. While most 4
cylinder engines will "fit",some of the industrial or power plant engines may not be machined and tapped
for the hydraulic pump mounting bolts. Also some of the industrial engines may have a cylinder block
with thinner webs which may not hold up to heavier loader use. Most of the thinner webbed engines are
used as power plants in air compressors, pumps and generators.Some of these do not have the tachometer
drive either requiring an adapter plate change. Try to find one that came out of a tractor, it will be
easier to make the swap, just some injector pump linkage changes, a hot wire for the shut off solenoid
and an oil pan swap and a line for the fuel return to the tank.
These engines are prone to liner cavitation if the coolant hasn't been changed regularly or have been
run with plain water.So there is a chance that it could end up with coolant in the oil.If you buy a used
engine with unknown hours,I would suggest pulling the head and having it redone, valve protrusion is
critical on these engines both for performance and cold starting. You can also see the wear on the
liners.If they look good, roll in new set of bearings and go back together with it. It should last many
thousand of trouble free hours with regular maintenance. If this seems cost prohibitive,consider tuning
up the gasser, you can buy an alot of gas for the cost of a diesel replacement.....

Unless the gas engine is in bad shape I'd run it ! Gas is sure a lot less money to buy then diesel right now.

An industrial front end loader is very difficult to remove and remount, will block your vision and will be a heavy duty battering ram that extend a long ways in front of a mower tractor especially when turning (think broken off fence posts, broken tree limbs, dented vehicles and machinery, caved in building sides, etc.). You might be ahead to: permanently remove the industrial loader; get a different tractor that is more maneuverable for mowing; or trade for a tractor with a quick-tach loader.

Gas engines are better suited for loader tractors than for mower tractors.

Also I think some irrigation engines had the balancers
left out. they ran slower and still had a lot of vibration.

Loader tractors are usually heavily weighted on the rear axle to maintain traction with a loader bucket. You tractor could weight 8000 pounds or more as it sits with the loader. Would you need to remove some of that weight for mowing?

ss55,

i didnt include much of the details about what i plan on mowing because its not pertinent to the question of repowering a 400 industrial. I only included that it had a FEL loader because it was on it when i bought it. I have skid steers, backhoes, excavators, and heavy pettibone loaders. So I dont need a loader on it however, for where i plan on running it i may leave it on because the ground its going to work is rough....very rough....and is not laid out in a fashion that something like a 2510 or 3020 could even work, and since i dont have all the money in the world i am not going to go buy a 20000 dollar oversized lawn mower from deere or kabota to do this work, i buy cheap john deeres when i can and do something with them, but this is not my first rodeo.

Do you agree with the original questions and answers as far as what engines will fit in the 400 industrial, or have any advice on swapping engines? Other than dont. haha

If you are looking for a project, go for it, it will work.

If you want to have a useful mowing tractor, it may be a disappointment no matter which engine it has. I would try mowing with it as-is for a few days or a full season and then decide how well it is suited for mowing before sticking a lot of extra money into the tractor.
