I am even more confused now.
I found a Russian video on how to change the strength of the secondary by moving the spring, and this has nothing to do with me, but what I found interesting is that they don't seem to mind that the secondary is spinning at idle.
Yet, in this one, this guy CLEARLY has the same blown-out bearing like what I'm dealing with. When he starts, the secondary is spinning and when he's done replacing it, it's not. Unfortunately I can't tell which direction this guy is installing his bearing.
