Yeah, Rob I respect your knowledge very much, but don't totally agree with this. I agree bearing crush is the one of the determining factors on a bearing spinning, as my previous post said.
But I have had the tangs hold them, prior to them spinning, when they have lost their crush.
The tangs are located opposite, on each half, and hit on the other half. I believe it is the metal losing it's properties, after losing its crush, that finally let the tangs release. The crush actually forces the tangs out into the slots in the rod.
After 45 years of dealing with this issue, I am not buying that article. I have torn down too many motors where the tangs were still holding bearings that have lost their crush.
I used to help with an alky aluminum rod motor, that had pins, that kept the bearing from spinning.
