I have a '44 H with no suffix in the serial number. Often refered to as "Duel Fuel" or "All Fuel", I understood that these tractors could run on gas, distillate, or kersene.
So what is the difference in set up with an X3 (Kerosene) or X17 (Distillate) tractor? Why the need for the individual types if another tractor did it all, and what components made them different from each other?

I just looked on the CaseIH site. They list seven different heads for the H. That's why you need to pay attention to serial numbers and type of fuel. Check the part numbers on your tractor. I realize some parts may have been changed through the years so good luck. David.

This is where a parts book comes in handy. I jnow that there are different head assemblies for kero, distillate, and gas. Not sure there is anything more than that except for shutters on some models.

At the time your tractor was built, distillate fuel was the standard, kerosene was an option, as was gasoline. Because your tractor was a "standard issue" there did not need to be a suffix to identify the fuel type. Kerosene and distillate are not the same kind of fuel.

That explains X3 and X1, but then why X17?

Do you know the difference between set up? Was the carb different or something?

The compression ratio was also different for each; kerosene, distilate, and gasoline plus for altitude options.

I think the only difference in the carbs may have been the main metering stem and those are fully interchangeable. The other difference is that the distillate and kerosene carbs had a petcock drain in the fuel bowl and the gasoline carbs usually had a simple 1/8" pipe plug in the drain hole. I say usually, there is some evidence that a few of the gasoline carbs DID have the drain petcock.
