As I mentioned in my email, if there is that much slop between the 5/8 in bolt and the 16 mm hole then those holes in the knuckle have obviously been elongated somehow. 16 mm converts to 0.6299 in, which is only 0.005 in (or 0.125 mm) bigger than the 5/8 (0.625) in bolt. This is the first time in almost 20 cars worth of kits that I've heard of this issue. How thick were the walls of the liners you had to put in? If you didn't have to drill out the holes in the knuckle, then theoretically the difference in the ID and OD of the liner will tell you how elongated the holes were. Also as I mentioned, buying a metric rod end wouldn't help because the metric thread on the body wouldn't mate up to the threaded hole in the link body. Quote:
Looking at the stress on that bolt, the minor diameter of a 5/8-11 external thread is 0.5168 in (as listed in the Machinery's Handbook). Putting that in double shear means the link would have to see an axial force of 62,832 lb to break the bolt. If that amount of force was exerted on a single link, I don't believe the bolt would be the biggest issue. And even the above is a conservative estimate since in reality only one side of the application will have threads in shear. Assuming a double shear condition with only one side being threaded (more likely real world) I'm calculating a force of 77,430 lb would be necessary to break that bolt. |
