Now I have come as long that I can do the first test.
One thing I found is that the RA and DEC shaft doesn't revolve as smooth that I has thought. It's much better than earlier but still, when revolve a turn I can feel that about 1/3 it makes a little bit more resistence. And it doesn't rotate by itself, but I can easily rotate it by my finger tip. The gap between the scale ring and chassis is enough all the way around, at least 0.1 mm.
The big 6 roller bearings felt perfect to me, only resitance I could felt was the gasket. Even the two conical bearings felt ok. Didn't replace them, only the 4 small roller bearings to the worm drive.
How low is the friction in your EQ6 mount that you have regreased?
