Nah, not in over my head, just made one mistake b/c I didn't know Growler's procedure. :-0
I tried smacking the hub. A lot, over the course of a day. Did nothing except gouge up the hub. Turns out there was a little bit of rust on the cam, which may have been making the hub stick. When the puller tool finally released it, the "bang" was pretty dramatic.
I put a little antiseize on the new one.
Well, torsion is still at -2.0 to -2.5 on a warm engine. What say ye ... adjust it? I don't have an MFC, so I'm not really sure if there's a mileage impact. I do notice a minor loss of performance, however.
I'm slightly concerned that my tension setting didn't "stick". The needle was in the window when I finished installing the belt. Tensioner was torqued correctly. When I got close to wrapping up the job the next day, I checked it again with a mirror and the needle was now at the low edge of the window. (Belt stretch? Temperature change? Both?) I really hope I don't need to tear the car down that far again!
