Hesse Hornet Info Wanted

• CATEGORIES: Features, Industrial-Welder-Generator, wanted This site contains affiliate links for which I may be compensated.

The Hesse Hornet was an air compressor manufactured by the Hess Manufacturing Company in the late 1940s(?).  The compressor used a CJ-2A engine to run, but only pistons 1 & 4.  The middle two pistons were used to compress air.  Keith recently bought one of these and was going to part it out, but changed his mind and now wants to restore it.  However, there isn’t much online about it.  Below are the links we know about it so far.  If you know of any additional info, please add it to the comments.

Here is a link to Keith’s pics:

    I have one of these units, the Engine/compressor had had a fresh rebuild then set up for several years.
    I got it running fairly well (carb likely dried out), didn’t get the governor set exact, but that sucker can really pump some air and quick.
    I would like to sell it or at lease get the necessary components to convert it back to a working 4cyl engine.
    The 4cyl engine is worth more to me than the air compressor

    Hey guys , Im posting on this old post to see if anyone has any parts for one of these Hesse Hornet Units. Im looking specifically for a Head Gasket for one and anything else someone might have. Any help would be greatly appreciated, you can reach me at
    Thanks for any leads in advance

    Ted, the last I’ve heard which has been a while but they do not make them anymore. I have heard that you can use a regular jead gasket but maybe someone can chime in and clarify. Hope this helps. I don’t have are know of anyone having any parts. I have been looking for the dipstick which is a shorter version than for a stock jeep engine because of the shallower oil pan. Feel free to email me if you need any info and I’ll be glad to share anything I have. Keith G.
