Detroit in a 4020

My 'boss' has a 4020 power shift with a blown engine. Put a valve though a piston,destroyed the head.... He has a 6V71 Detroit in an old JD hay cuber.I know there are 5020s with 8V71. Can we do this? It would be so cool! The tractor also has 26x32 rear tires.Be an awesome puller.
 
Kinze did conversion for them. Check this out:

AS you can see, the engine is too wide to fit nicely. The hood was cut to fit the thermostat housings. I have seen many 4020 with Cummins 555 and they look much nicer, even if the Cummins 555 have poor reputation (at least on the internet).

Funny thing to watch in the 4020 Hycrop movie is the tach. Tractor sounds like 5600 rpm at 1700 rpm.
 
A little off-topic but since we are in day dream mode I think it would be interesting if someone either adapted common rail injection to an old piece of iron or transplanted a complete common rail engine.

Similar concept to what that fella did with his compound turbo 720......

Not at all practical but if money were no object, why not? LOL
 
Kinze could do about anything.There were a few 4520/4620/5020s in our area with Detroits and you definitely needed hearing protectors.The Cummings worked better in the larger tractors and they just sold a very nice Kinze repowered 8850 with Cummings and it brought $35K which was what it cost to convert it. I thought about a repower of an 8650 but decided to sell it and buy a Steiger C-IH with factory installed N-14
 
I am not a Detroit Diesel fan,one of the shortest lived diesel ever made, but they were still building them at the factory, when i was last there,guess who buys them, the military !
 
Have some sense of humor when I ask "Do you hate that 4020?" Plenty of Deere combine motors that would slip in with minimal alteration. Also, I do see 4020 blocks and heads advertised periodically. If you just want to be different I would put a Cummins 5.9 in.
 
Back a few years ago when I was still teaching school there was a fellow east of Toledo with a5010 or 20 with an 8 V 71 and he also had a 4010 or 4020 with a 6 V 71. We had a plow customer that had a 5020 with an *V 71 which he really liked.
 
There are also plenty of 4020s to go around. Enough for the purists and enough for the guys who want to play around with something different. I'd say go for it Delta.
 
The Deere 955 cid V-8 was a clone of the CUMMINS (no G) 903 if there ever was one. The 8850 used the 955 and I bet the 903 bolted right in! Think it was the 870 Excavator used the 955 too.

Kinze made a lot of money putting Cummins engines in equipment.

Shortest lived ? Least have some actual evidence rather than hearsay.
 
Why would anyone copy a 903? lol They are still being built everyday though, The military loves them!

Glen,
Transplanting a complete Waterloo Deere common rail engine into another Waterloo tractor would be fairly easy if you take a 'pre-emission' engine, and you do not choose a power setting that oblige to have a big air to air cooler.
The wiring harness that needs to connect to the engine is very simple. More or less, you only need to provide to the ECU to start:
- +
- -
- key on signal
- throttle signal (basic variable resistor connected to current lnkage)
- Starter on signal

Then on top you have gages and other stuff in the ECU that are not totally required to have on your tractor (I mean, the ECU needs to know the temp so you need the temp gage connected to the ECU , but you can put a regular mecanical temp gage on your tractor).

Please look at See wiring diagram p130. - It is much simpler that many people think.

I have always tought that a 8.1 (496) out of a 7710 or 7810 would be an awesome repower option for a 45-4620, or to repower a gutless 8430/8450. That would be a torque monster then. Let's wait few more years and those would be cheap engines...
Some newer engines are missing threaded holes on the frame rear mounting pad. The 12.5 to 13.5L have issues with the oil filter interfering with the frame.
 
Agreed.

Preferably a common rail powerplant that is pre DPF / DEF. EGR delete if needed.

Minimalistic to keep things neat & tidy.

Power settings best kept below the requirement for a large intercooler or there'll likely be drivetrain pieces that try to escape anyway....... LOL

Maybe the president will return Off Road emissions back to Tier II ?
 
Kinze sold conversion kits around 1970, those might be expensive to buy now. What is the budget, over $10,000 without the tractor or engine?
