interchangeable parts

[dieselmania]

Hey guys, wandering if anyone chould give me some info on interchanging parts on the 5.9 cummins and 5.9 John Deer i.e. fuel related. I work at a military maintenance facility, where I rebuild drive line parts i.e. 3116 & 3126 Cats, 5.9 cummins and 5.9 John Deer engines; 5 ton axles, hummer transfers; i've read in past mags about someone running John Deer injectors in a 12v cummins, I never even thought of changing parts till I read that. I can't do anything like that at work but was wandering if anyone has done this and can you enlighten me on that subject. Also I just read something about someone used the injector pump and injectors off a John Deer and put on a 5.9 12v cummins, not sure if they used it off a 5.9 John Deer or what, of course the ideal is more fuel/more power. Is this a hard change and how much more fuel? Why the change? Is it less costly? Or maybe it was lying around and someone said, "lets try this". What's up!!!!!!

I guy I know uses JD injectors in his Case pulling tractor. They have to get the head machined for them to work. The only reason they do it is because their pump guy only works on JD pumps and injectors.

I posted this on your other thread

well..... unfourtunatly there isnt too many parts pbetween the Cummins and Deere that are interchangable, the JD uses what the call a pencil style injector that is clamped down in the head with a small peice of steel where as the cummins has a thread in style injector. as for the injection pumps, you could probabaly swap them out with some fabriction, but by no means is it going to be easy, All 5.9L deeres run rotary pumps, whereas the cummins can have either an inline or a rotary pump. The injectors that the guy was running are from a larger deere engine E.I. 404-466ci+, then tap a 24V head out to the deeres threads on the injector, modify the valve cover, and your good to go..... hope this helps, Brad

thank you for that bit of info, didn't know that they were from a larger John Deer engine or that any mods were done to make it work but their must be something to it or else they wouldn't be doing it. Would like to know more and what advantages are their over the P-pump. I have read about several cummins owners with this mod but no explanation as to how or why.
