@YYCHM and anyone else I missed.
I am home now.
The eccentric is on the outside not the inside. I bet that's an assembly issue because it's on the inside on other members saws and my manual says inside too.
There is no eccentric indexing. At first I thought there are no flats either. But they are there - just very hard to access. I had to make a thin wrench that was thin enough to fit between the bearing and the extension bar. The eccentric is a very tight friction fit.
After relieving the blade pinching force, the blade no longer pops off. Yippee!
Here is the drive
@Degen, and the top gear is after that. Hope it shows whatever you need. The blade looks like it's touching the drive, but it isn't.
