Rounded Fan Hole

Michael McKelveyAnn Arbor Supporting Member

I am replacing my alternator backing plate and I discovered my fan hole is rounded.

It seems like this would only happen if the nut is loose but I had to use an impact wrench to get the nut off.

Other than torquing the nut to the proper value, is there anything else I can do to prevent this?

My welded and balanced fan came from Berg. Is that still the best source?
