AllisChalmers motor construction

Things aren't exactly located correctly or to scale, but it still gives one an idea of what the components are.  #1. I assume represents the engine block (foundation of the engine) or the engine assembly. #2 represents the carburetor which mixes the gasoline (fuel) with air so the mixture can be ignited to make the engine run. #3. Is the air cleaner to filter out the dirt and dust in the air. Clean air then enters the carburetor to mix with the gasoline. #4. Engine oil filter (oil pump is located inside the engine...cannot be seen). #5. Is where the governor is located, which is the speed control for the engine. #6. Timing gear cover covers up the three internal gears that make the camshaft and governor operate. #7. I think this is to show an ignition system altho it isn't a six cylinder engine...it is a 4 cylinder.  #8. I think this is the starter altho not quite exactly where it should be. #9. Generator provides electric power for the lights and to charge the battery to operate the starter and ignition. #10. Crankshaft pulley which operates the fan and generator thru a belt, which is E12.  I imagine E11 is the water pump which circulates coolant thru the engine for cooling purposes.
