Today sucked a lot less than yesterday.\u00a0 I got the oil cooler attached to the engine mount, which is a significant milestone.\u00a0 I also learned that you can attach anything at any angle using this One Weird Trick, which I’ll describe later.<\/p>\n

The oil cooler itself doesn’t weigh all that much, and there are no significant loads placed on it.\u00a0 The attachment method is Adel clamps, which serve to isolate it from some of the engine’s vibration.\u00a0 Given that, it seems that the beef I put into the brackets is unnecessary and an example of overengineering.\u00a0 That said, it’s really, really important to me that the oil cooler stays firmly attached and that it retains its structural integrity until the end of time.<\/p>\n

\"Forward

Forward Bracket – Oil Cooler<\/p><\/div>\n

The\u00a0 Weird Trick I mentioned earlier is shown below.\u00a0 On the right of frame, there is a large-ish piece of angle connected to another angle bolted to the cooler.\u00a0 The way this works is that there’s enough span on the opposite side to cover the distance needed\u00a0 by two Adel clamps when the angle is laid up alongside the tube and the adjacent side lines up with the angle connected to the cooler.\u00a0 This made for a much easier test-fitting, and the same technique is in use on the bracket shown above.<\/p>\n

\"\"<\/p>\n

So it’s come to this.\u00a0 The oil cooler is suspended where it needs to be to get air to it from the big hole in the baffle. At this point, the whole setup will take nearly my full weight, so I’m not terribly concerned about the parts failing.\u00a0 At this point, the weakest parts are the flanges of the oil cooler itself, and they can be reinforced with angle or bent sheet.<\/p>\n

\"\"<\/p>\n

This is the best fit possible for access, airflow, clearance from other important things (fuel line, for example).\u00a0 There should also be enough room to get a\u00a0 fiberglass intake plenum between the cooler and the middle engine mount tube.\u00a0 I measured.\u00a0 But “best fit” means the least hideous compromise.\u00a0 \u00a0Now for shaping the\u00a0 plenum.\u00a0 Yay, fiberglass.<\/p>\n

Happy New Year.<\/p>\n","protected":false},"excerpt":{"rendered":"
