I read this three times before it finally dawned on me what the problem was. The nut you are trying to use to "lever" with is not the one you should be messing with. The big one (19mm) in the center of the tensioner assy is the one that has to be loosened for any adjusting to take place. If you don't loosen this fella first, you're gonna break the whole thing into junkland. Sounds like you ought to replace the whole tensioner assy and start over..BTW, the pointer for the tensioner adjustment is not on the pulley, it's on the front of the tensioner body behind that big bolt..
