Hey guys,

I have been spending quite a while looking at different diesel engine options, outside of the 'normal' 4bt and isuzu 4bdt.

Its a JD (John Deere) model 5030, 3.0 L straight 5 turbo.

99 HP@2800 rpm, with 253 ft/lb@1700 rpm.

Weighs in at 633lb, overall size is comparable to a cummins, slighty shorter overall height.

SAE #3 mounting surface, with other options available.

I spoke with the local rep, he said each motor is spec'd for the application and engineered to fit the criteria needed (bolt pattern, governer, de-tuning, etc.). Its pretty much a drop and bolt in application, the engine comes with everything besides a cooling system. Its 12 v, with a 24v option and overall lb/hp-hr fuel consumption is very similiar to a 4bt. They are supposed to be very smooth and apparently quite.

Brand new engine in the crate for approx. $4500, seems like a steel when used 4bt's are going for $2500.

You can check it out here, http://jdpsesc.deere.com/ESComp/servlet/com.deere.enginedb.servlet.model2.EngineSearchServlet
For engine type pick 'industrial'
For engine model pick '5030'

I dont know the difficulties of mating a OD tranny to it, but it has to be possible.
 
The link does not say what the maximum revs the motor is capable of unless I missed something. It may be too low reving with a big flywheel for vehicle use, I think you would need to check this out.cheers

There is a power curve graph showing max revs at 2800. I spoke to the dealer rep about this and he confirmed the 2800. Not high by any means, but within 'acceptable' range IMO-
 
Its a tidy looking engine Nick. Have you checked the height? It looks to me as if the oil pan might be at its deepest where the front diff is.
With the high perched alternator and the depth of the oil pan you made need a hefty suspension lift.


That single,does everything belt must be 8 ft long:eek::D So Im guessing it must be a non interference motor;)

Rosco,
I thought it looked tall to, but at 31.5" its right at 4bt height. The alternator is a good inch above the rest of the motor. I am sure the alt. could be located in a lower position without much difficulty.

For the record:

JD5030-
Height, 31.5"
Width, 22.3"
Length, 31.5"

4bt-
Height, 30.6"
Width, 22.9"
Lenght, 30.1"

You lost me on "non interference motor":confused:
 
the sae #3 bellhousing has a lot of folk lore around it. I googled it and found some say a chev tranny will mount, others say it will not.

How abouts you buy the engine and we find out :)

I will split it with you, I will take the first 200,000 miles, you can have the last 200,000:D

When I had the rep on the phone, he felt confident that they could work with whatever tranny I had.

Maybe somebody else can chime in that knows more about this than me, but can't a sae#3 can interface any chevy tranny...with possible issues with the input shafts?
 
do a google search. I found a bit of info. But they also talked about none of the holes lining up. And it had to be drilled.

Not being able to go over 2800 rpm is pretty limiting. It makes picking gear ratios very important.

Find out the market for these engines. If you bought it and found out it would not work, how hard is it to sell it? Is there farmers all over who buy this thing?

What kind of machine does it run in? Those questions should be answered before buying.

Last 200k miles, no fair. No deal. All this fuss it better run for 600k miles or more.
 
I searched a bit on sae3 since I was planning to put a mercedes truck engine in my 80 series.

I found out that sae#3 does not bolt on to anything that is not sae#3, no chevy, no dodge, it seems that isuzu uses the same diameter on some of their backing plates but the bolt pattern is different.

You may want to contact High Impact Transmissions http://www.high-impact.net

I contacted them and they emailed me a telephone number for someone that was developing a sae#3 adapter. Unfortunately I deleted the email when I decided against the Mercedes engine so I do not have the phone number or the name of the guy but I am sure you can get information from high impact.

Not trying to put you off... but definately NOT an engine I'd be fitting in a Cruiser!

We've had some experience with them in some "green" products (4020 and 5025 tractors), not inspiring at all and not built like any other JD engine.

They run individual injection pumps for each cylinder, run off the cam, all mechanically linked by a rack and plastic governor gear. Also no cylinder liners.

I think with the limited revs and not having masses of torque and horsepower the performance would be pretty dismal. just like the tractor motor it will probably running in 30 years time.:D :beer: :beer: http://www.off-road.com/tlc/faq/engine.html#HD_NM_21
