Combines engine transplant

I also own a Dodge Cummins, I don't think the Cummins B(5.9) has enough long term guts to hold an N5. The Cummins C(8.3) will easily do the job, it starts at about 150hp and goes up from there. Notice that no tractor applications use the 5.9 above 150hp. Its a great engine, just not big enough for the bigger jobs. Remember the AC 670(426cid) was maxed out in the N5 and had lots of trouble in the early N6s. A good Cummins B might have some trade value for a good Cummins C for the N5.

We had the 5.9 cummins in our l4. It was rated at 177 and had plenty of power for that particular machine. We had a 24 ft header and it handled it fine. I don't know what kind of conditions you are operating it(hills, big bushels, etc.) All I know is that it was a good motor for that combine. My 2 cents.

No big or long hills, mostly flat ground with a few rolls. I don't do corn and seldom would I grow soys. Mostly small grains and flax.The engine is rated at 180 hp in my truck but could be cranked up a bit if needed. Did you put that engine in your l4 and if so what modifications did you makeIJ

No. It was the engine that came from the factory. The l4 was made only a year or two around 1990. It was a venture started after Deutz stopped the conventional line. It was manufactured in Mexico, and was not considered a success. We really liked it, but was just not big enough for our operation. I think the N5 is rated at 190, but the cummins should have more torque, and be able to handle it fine.

new development, just talked to a local shop with a good used DT 466 int.Was told rpms would not be an issue with this motor and would probably run around 225 HP, same as N6. Now, can I make it fit.

i beg to differ with you red the 5.9 liter onan_cummins was originally designated as a 300 hp 700lb_ft of torque log skidder engine there are people out there reliably running 470hp and 900lb_ft of torque from the 24valve 5.9 wouldnt be scared to transplant it not sure where this n5 is located, but you should be able to find a good motor_pulleys etc... from an n7 in a salvage yard cheap i recently paid $4,000 at auction for one with only 1800 engine hours august wieser rosholt, sd

Now if you make that work, we all need to see pictures of it! Imagine, a binder engine in a silver shed . . . .

I'm in northern Ontario. I've called a large wrecker in southern Ont. but he hasn't got any 670I worth selling. N7 wern't a big seller around here as they were to big for the size of operations. lots of N6 and N5 but just nothing availible. My other concern with the N7 engine is the much higher HP would maybe distroy the drive line of an N5. If it would stand up to the power, then I would certainly consider one as it would be much easier to install.

I have also been told by a Cummins technician that the 5.9l in a marine environment can be tuned up to around 650 hp. This sounds high to me, but he said that cooling was the issue at these horses. He said a boat with new cool water flowing continuously thru it from the lake was the only way to keep it cool. I came upon the topic while I was seeing if I could turn my Dodge up anymore. He said he has worked on more than one boat rated at this HP. We also have a White 145 with this engine in it and it dynos at 160HP. Should work fine for an N5 if it will fit.

Keep in mind the load is different marine vs combine.. The marine application would have absolutly no shock load and you probably will have some with the combine
