Original paint and only three owners, including the U.S. Government. On the day we saw it at the Portland Tri-State Engine and Tractor show, it was showing 89.9 original hours, just 20 more than when purchased, and Mike kept it running most of the three days of the event. The radiator is made up of bolted-in segments, with segment on the right being a massive oil cooler. The unit bears serial number 197 and the manual lists this unit as primarily being designated for use with the Signal Corp SCR- 615 A or B portable radar installation which required a detachment of 54 men to operate around the clock.
The Cummins H-Series diesel debuted in 1931 and it’s derivatives are still produced today in some parts of the world. The Model H was inarguably the foundation of Cummins’ success. This is an HI industrial series engine with direct electric starting. It used a Cummins designed and built single disc injection pump. The oil pan holds 12 gallons of oil and combined with a 24 gallon cooling system, plus a huge oil cooler, this unit was designed to run for days or weeks at a stretch at a full load. Your 1943 tax dollars at work! Mike has the covers off the back of the generator head and exciter for inspection and cleaning.
The engine control panel is fully operational, though Mike has not yet figured out how to use the “Flame Thrower” (see lower right). This was a cold starting device to heat up the intake manifold for cold weather starting.
