Just looking at the last video it would appear to me that the gap is larger than the .016 to .020 gap that is specified. A large gap puts too much load on the three dog bone springs.
A measurement of the shaft would be a good idea.
im confused "There is no need for an interference fit on the inside diameter as it is clamped to the shaft with the washer".
The interference fit would refer to the inside diameter and the washer clamps the bearing thickness, two different situations.
i know nothing about this but is it possible the washer is worn out? Seems to me there is a lot of guessing here and the owner and mechanic would be better off and money ahead if they would get an inperson / hands on second opinion. Videos and telephone calls from different states are noway to actually diagnose any mechanical problem of this sort.

wouldnt the inside diameter be where it slides onto the shaft? If thats the case and no need for an interference fit then why check the shaft? Again i know nothing about this just questions
RED DOG was right about this one!
But I'll give this one more try. It seems that the mechanic friend here is tripping on the minor difference in the gap when he spins the pulley around. Yes, perhaps he either needs to add or remove shims to get it closer to spec., but my experience is that the gap will vary slightly. Unless the pulley clutch plate on the pulley is warped out of flat, there is no need to "trip" on it. What's important is that it clamps down flat with no gap when it is energized(no space for feeler gauge anywhere all the way around), that will let you know if the plate is warped. The electromagnet is energized and clamps down the pulley clutch plate at around 2k rpm, or sooner depending on the engine load. So the insignificant imbalance of the pulley clutch plate never gets to the high SC speed, because the minor imbalance disappears when it clamps down to the electromagnet. If all this is true, you can put the belt back on and drive it.

Bob, you can see in one of the videos he had wrapped the shaft with foil and the sc pulley still went on with destroying the foil the shaft is worn out and egg shaped .

Unrelated to this quote, I have pictures from the ordered blower and my blower. The shaft difference is pretty insane.
I do want to thank onehundred80, you have been the most spot on for this post. I will be doing what you suggested with my prior shaft, and using this other blower for parts incase something happens again.
My car should be up and running by weeks end if I'm lucky
To confirm:
The shaft was worn from use, and the pictures will demonstrate that with a measurement tool.
Thank you EVERYONE for all of your input, I did document this as well as I could, I did not record my initial issue, but hopefully this thread may answer some questions in the near future!

Egg shaped is hard for us to imagine. How could that happen?

There is more to this story than we or the OP know. The whole area was rusty looking with rust powder where you would not expect to find it.
The feeler gages used look a lot thicker than the correct size of .015” to .020”.
I guess it is conceivable that at one time an after market pulley was used with the wrong bearing or spacer and this caused damage to the spindle.
