Sure wish one of the big three would pick up John Deere as their diesel manufacturer. That would be great. JD makes a 6.8L inline 6 that would work well. I'd prefer Ford mostly, and would love to see them dump the V8 Navistar and go to a sturdier, more powerfull inline 6.

I've had the oppertunity to run a lot of different brands of diesel engines and I personally have found the JD's to be one of the best. Here on the ranch we have 2 JD motors, one Ford diesel, one Cat, two Cummins, one International, and two Detroits....all in different farm equipment we use. The JD's are darned good engines, and powerfull compared to our other engines that are nearly the same HP rating.

Yeah, they do make great motors. But I think that they, like Cat, just dont need the light truck market, nor have any interest in it.

Yeah, you're probably right. I have a 6-8L'ish JD inline 6 thats in a basically junk combine that I am debating trying to put it in something. I've got an Ford F600 service truck that weighs 10,500lbs full of tools and supplies and the stock 370 V8 pretty much sucks. That JD motor I have that is around 200HP would drag my F600 around easy. Thinking...... I've never seen a green motor under anything but a JD piece of equipment before....it would be pretty original.

You do know that the throttle/pump/governor behavior is totally different for off-road diesels right? Not exactly ideal for on-road applications from what I hear. Not sure the details or what it takes to change it, but it's a warning I've been seeing a lot in the 4BT market...

I've got a lovely '78 Chevy that might be a nice candidate. :D

Until the weight snaps the dana 60 in half :rolleyes:

Details, details :rolleyes:

Thats why I'm considering it in a 2.5ton truck. ( I think thats the rating of an F600?) Regardless, I doubt the motor is really all that much heavier than the 5.9 Cummins. The ISB weighs right at 1K, a Cat C7 weighs 1,150lbs, and I bet my JD engine is close. I would think it would work over a D60, a lot of Dodge guys have big steel bumpers and winches which probably adds 200lbs? Roughly of course.

You do know that the throttle/pump/governor behavior is totally different for off-road diesels right? I don't follow. A lot of our tractors and miscelanious equipment has both hand and foot throttles. Most of the smaller inline 6 JD motors are governed at about 2400 RPM's. With the JD injection pumps, you can turn up the engine speed with a screw driver. How far I don't know but regardless, I'd use a nice 6 spd transmission behind it with tall gears in the rear end. 2400RPM's would probably be enough anyway. The 12v cummins in the early Dodges were governed at 2500RPM's, and some came with 3 spd autos! The JD motor would not have a problem with tall gears at all anyway, it's low RPM torque makes the Cummins ISB look like a Ford Navistar. ;)

The only thing that has me bothered is the smoke level that it might put out while under acceleration. Older JD's pour the smoke, but probably could be regulated by a steady, easy throttling.
