John,
The engine is complete. The valves and rockers were all exposed and required oiling by hand. The Manzel oiler in the picture oils the cylinders. The crankcase is compartmentalized (sp?) meaning each cylinder has it's own oil supply. The 5 tubes you see coming out of the distributor (on the left) go to each of the 4 crankcase areas below the cylinders. The tube on the right is the supply from the pump. There is an oil pump driven off the cam which pumps oil into the distributor and then fed out the 4 tubes to each crankcase compartment. Make sense? The individual crankcases have an overflow cast in the block which feeds the oil pump.
Evidently this was their idea of making sure each piston and rod was sufficiently lubricated when operating on slopes.
The front of the engine carries the clutch. The rear has the red flywheel you see with holes for starting it with a bar. The face of the flywheel has 2 different sized flat belt pullies, one for driving the water pump and the other for driving the radiator fan. This particular engine was mounted atop the harvester with the radiator mounted to the side.
I'm not sure on all the engines sizes that were made, but the designation 45 means the horsepower. I know they made a 45, 60 and 75.
