For sure, measuring in that area is sketchy at best, but if the measurements are close, it looks like the gap is now .06mm bigger than it was after I first installed the pulley, and again, as you said, it appears to have "shrunk" .04mm from the initial installation.
Like you said, measurements that incremental are of little consequence, but I did it because I didnt like having the gap being smaller than Code 3's spec's after the pulley "settled in". I assume there cant be a gap of less than .2mm because of heat expansion, or pulley spring fatigue, whether the SC clutch spins freely or not.
As I said, my SC clutch DID spin nicely when the car was off, and even with the shorter gap, I could stop the SC clutch with my bare hand
**when the engine was running**.
(
**NOTE!!**-- I DO NOT recommended trying to stop the SC clutch while the engine is running with a bare hand!!
I should NOT have tried doing that!!).
