In this update, we'll show some photos of the cleanup that was needed on USA 8537 prior to getting started on the body preparation.

GE 45 tonners have a single traction motor on each truck coupled to one of the axles through an oil filled reduction gear box. The second axle is coupled via a chain drive or side rods similar to a steam locomotive. 8537 uses side rods. One of the items on the daily inspection during operation is greasing the rods. During operation, that grease tends to fly and smear everywhere. Many hours were spent by Bob A, Jim P, Sean M, Dave V, and Linda E removing that grease and cleaning the rods, counterweights, and sides of the truck frames.

The engines themselves, along with the floors of the engine compartments, received some attention as well. These engines are Cummins HBI inline 6 cylinder normally aspirated diesels rated at 150 horsepower each. This engine design is over 90 years old. We have five of them at the museum, two on the 8537, and three that run the power car in the Nebraska Zephyr. The #1 on the 8537 has the newer style PT fuel pump. The #2 engine still runs the original single disc fuel pump. It was interesting trying to get the mechanical throttle linkage adjusted to make the engines power curve synchronization be fairly close throughout the throttle range with those two very different pumps.
