Stupid me, for a moment I thought I had to keep tightening till the gap closes 
Destruction is a likely scenario when you go to a dealer, in many cases the techs are as dumb as a box of rocks. I stay the f away. Even bought my own lift so I can...On the SC60 it's a single pinch bolt. A dealership destroyed the bolt threads right at that gap when they replaced the chain on my 2014.
