New aluminum fan blade problem

[Richard Knight]

A further comment. The modern leakless pumps often have a larger diameter to the cast nose of the pump due to the ball bearing installed in that location. As mentioned by Kieth often the casting is not concentric with the shaft. Some folks fail to see the big picture. With 5 million As produced and at one time countless producers of spare parts I can imagine maybe 20 million pumps being produced or more. Anyone who thinks they are all the same is not being realistic. Grinding the cast iron nose has been going on since the cast aluminum fans became available. It is a small price to pay versus having to buy a new radiator, hood, or having an unexpected lobotomy.

I say bill the mfg. for your work, trying to make the crap they are putting out fit right. Of course they won't return your calls....

Takes the 'fun' out of owning a Model A.
