Talking about engines here. Am in the process of rolling in rod and main bearings in a 7F, 3306. The other day, laying underneath the old pig, and just marveling still at the simplicity and beauty of the bottom end of that inline six. Then got to thinking that when it's turning and burning, it is truly mathematics in motion. This journal is measured and built to thousandths of tolerance, as are most all of the parts and gears. This gear must be this diameter with this many teeth, to do this job at this time. This piston must fit this bore, and travel this far to create this much compression, and this much fuel must be fed to this much air at this time to create this much power. Mathematics to build it, mathematics in motion running. A collection of metal, that all together, make a living, breathing being. Must have air, must have nourishment. Has vital pressures and fluids. Running, they fart continuously and like us, some stink really bad and others, well, not so much... Sister engines, on the same assembly line, and they will run, or sound slightly different, and have slightly different personality's. Have rebuilt many over these many years, though not on the scale of guys like Truck Shop, or Vetech, or TC Tractors, or a thousand others of you. But still marvel, and am slightly amazed, when that collection of different parts lights off, and it's blood pressure comes up, and the temp rises, and it LIVES. Then, in a personal moment, I'm kinda proud. I did that. I gave it my blood usually, and sweat, and skin....a part of me one way or another. Yeah, maybe I'm sentimental, or maybe just mental the Wife says, but I think another Mechanic will understand. Engines, like so many other things we deal with aren't really magic, but when we fix either them or a thousand other things and problems, sometimes others think we are magicians. I always get a laugh out of that, and I always share this quote with them. "When you know what the Magician knows, it's not Magic anymore...." Have a good afternoon my Friends, and the best New Year you can. Chuck
