Looks good, but I don't see a jam nut on the turnbuckle. What's to keep it from self adjusting through vibration?-Todd

I had jam nuts on mine. You can see them in the first pic. I also used washers underneath. Sadly, I forgot to tighten them and found after IDK somewhere around 25,000 miles *when I was putting the IC in* that they were loose. I never had to readjust the alt though. I snugged up those jam nuts and ran it until the engine blew right at 40,000 total miles, again with no adjustment to the turnbuckle.
Yes, I had them, but I forgot to tighten them. I saw my washers sitting there with no nut on them and got to thinking back almost a year and remembered then I was going to and never did. It did not only not loosen in 25,000 I did tighten them up without retensioning the turnbuckle and it went to 40,000 when the engine ate the precup.
Loosen.-Todd
I've got a couple of hundred miles on it and it's doing fine. Belt hasn't loosened and no flops. One good way to tell if your belt tension is tight enough is: the fan should not be able to be turned by hand relative to the pulley. If it turns, it is slipping.When I started this project, I started grinding both the alternator and the AC bracket (on my spare Eco engine) for mock-up. Now that I am done, I now realize that no grinding is necessary unless you want to use the stock 13 x 947 AC belt (which I am not sure if it is possible without taking too much metal off). Just use a longer belt!Fatmobile, what was your reason to do all that grinding?

I used a gates 13x965 I think those gates belts are beastly I doubt one would ever wear out one of these setups if it was always tightened up and kept up with.
