Sintz Engine

As this issue is being compiled in late February, this writer at least, has a longing for some warm southerly winds to herald the beginning of warmer weather. For those of us who don't keep the shop heated all the time, the winter months slow up any engine and tractor restoration projects. Cold hands and cold feet sure diminish one's enthusiasm.

We find it interesting indeed that our previous mention of a Junkers diesel engine in our stable is still generating letters and even a few phone calls. Just to clear up one point, this single-cylinder engine is of two-cycle design. The two pistons travel toward each other, toward the center of the cylinder where the injector is located. Just as soon as we get warm weather, we'll take some photos of this engine. Our sincere thanks to all who have called and written us about this engine.

A final note regarding the Junkers engine-Hobart Welder Company bought three diesels at a Trade Fair in Europe during the early 1930s. One was the single cylinder engine we have, and the other two were of two-cylinder, opposed piston design. These were tested for possible use with Hobart welding generators, but were never adapted on a production basis. So far as is known, these were the only three Junkers diesels imported into the United States, although a few may have gone to Canada. No doubt due to deteriorating relations with Germany in the late 1930s, no further work was done in this regard, and after World War Two, the design was apparently discontinued entirely. In fact, we have been told that the Junkers factory was destroyed by Allied bombing missions.

We talked with Mr. Bill Starkey over at Starbolt Engine Supplies the other day. Bill continues to express his concern over safety or the lack thereof at engine shows. Especially during the past year or so, we've published several 'horror stories' that were real life experiences for a few of our collectors. At the risk of sounding like Casper Milquetoast personified-folks, we need to be careful about this old iron, whether it is engines, tractors or whatever! We can all have a lot of fun with our hobby, and we certainly are doing the right thing in showing our gems at the shows. Almost anything can happen with these relics, especially since most were designed with almost no thought of safety for the operator, much less for spectators. Mr. Starkey speaks of a valid concern we believe, in that if we do not police ourselves and exercise safe practices, the day will come when some politician or some bureaucrat will decide to do it for us. If somebody grinds up a finger in the timing gears of your engine- perish the thought! And one other thing-why not carry a fire extinguisher in the box with the oil can and water pail?

Our questions this month begin with:

24/5/1 Crawler tractor Q. See the photo of this little crawler tractor. Can you identify the model, the proper colors, etc.? Forrest Greene, Rt 10, Box 472, Lenoir, NC 28645.
