Dual fuel H

luv2wrench · Oct 5, 2010

I just bought an 1943 H. Has small starting tank. Is this somewhat rare? Somebody said my manifold is a dual one too. I have seen two different manifolds for the dual fuel H. Mine has a smaller 'block' in the center then a Super H dual fuel i saw. I cant load pictures just quite yet. How rare is this set up? tanks.

Nearly ALL Hs up to maybe '46 or '47 had the small tank and the distillate manifold. It is somewhat unusual to find one today, but it is not rare. The distillate manifold has a lever coming out of the side, and also has a sheet metal "heat shield" fastened to it. If your manifold does not meet that description, it is a common, gasoline only manifold

Much more common in H's and M's prior to World War II. Straight gasoline with high compression heads pretty much from 1944 till end of production. Most kerosene tractors were adapted over as they received overhauls or the manifolds ate out. I have got a 1941 kerosene M with the original manifold shot and flat top pistons. I hate to change it but I can not afford 1000 dollars for a used original manifold. At some point we will pull it down and see what pistons are compatible with the existing head (for gas operation) even though the current ones are good.

You can run it on straight gas if you want to to if it isn't already. I've noticed thats a frequently asked question with the dual fuels. I have a 46 H dual fuel that has never run on the kerosene distilate

I have heard that quite a few came with the kerosene tank, but that many people afterward converted to straight gas. Thus not too many are seen this way. For the past couple of years I have looked at many International tractors on craigs list, in my area, and I have probably only seen perhaps 2 or 3, with the kerosene tank.

Dual fuel is a JD term. IH had different engines for distillate, kerosene, and gasoline. Since H production declined in later years my guess is that the distillate or kerosene engines out numbered the gasoline engine. The gasoline engines pretty well took over after WW II.

Kerosene is different than distallate and it wasn't held in the little tank. You put good gas in the little tank to get it started and then ran crap gas in the big tank for doing the work.
I would say that an H that was gas from the factory is more rare than one that is dist in SE WI. It is rare to see one that has a funcitoning dist setup ie heat valve, heat shield, shutters, etc

As stated already, it's not "rare", per say. However, very few people have them still set up to run with multiple fuels. The issue is that the heat box valve in the manifold rusts in place because farmers stopped using distillate years ago, so the valve didn't get moved.

I have a '44 that I'm restoring back to an original look. It won't work for multiple fuels because of the manifold, but it will look like it can. It will be a Parade King (not queen... his name is Oscar after my Grandfather), so I'll be using it for "showing" purposes.

Put up pics! Let's see what you got! If you need help getting pics set up, let us know.

I did not realize that. I guess I have heard faulty information. Sorry for the confusion. Thanks for the correction.

Not to mention the fact that you couldn't find much distallate now days :lol:

It's all good. A lot of people don't know a ton about the big tank, little tank thing. It is kind of like filling the fuel tank up with coolant on a 4020 :shock:
