I'm starting the first hub. The knob would not turn to start. As I took pieces apart they all seem fine and spun, including the small rollers. In fact that spun real easy. That grease looked like a petroleum jelly color and looked good. I gave not taken all out yet but plan to. At one point during tear down I was able to get the know to move to the other position but now it won't move again. It's soaking over night and I'll see in the morning. But the 12 larger rollers all have vertical scores in them, which doesn't make sense to me as I assume they are supposed to spin. See pic below. What do you guys think?
