Hercules Engine

 

This huge rare Hercules 4 cylinder ca. 136 HP model TXO - 6 3/8" x 7" engine was purchased in Canada in July of 1994, and trucked to Carrollton Ohio, where it has been kept ever since. The previous owner noted that he had run the engine, but I never tried to start it up. This engine was used on the largest Star Drilling Machines back in the late 1920s and during the 1930s. It was the largest 4-cylinder industrial-type engine made by Hercules at that time. The Star Drilling Machine Company name is prominently cast into the rear control panel. The engine weighs ca. 3400 pounds according to the specifications. I hoped to restore the engine to original, but at 85 years old I realize I'll never get it done. Note that in the control panel there is an oil gauge, but the other instruments are lacking.

 

Look at all photographs to see the present condition. When restored and painted, with its cast aluminum oil pan, cast aluminum and polished water outlet manifold on top of the engine, polished brass priming caps, etc, it can be an excellent attraction at a show, mounted on its own trailer. There was never an electric starter on the engine. You start it with the starting crank which they note that "it looks big enough to be a connecting rod, but you can turn it over easily".

 

The Hercules TXO is stored in Carrollton Ohio and must be picked up there. It is too large and too heavy for a pickup truck.
