Dave Henderson Posted March 9, 2010 Share Posted March 9, 2010 The pump appears to have been rebuilt at some time using a non-original steel packing nut. The fan is an aftermarket replacement for the original "propeller" type fan that all Model A's originally had. . Link to comment Share on other sites More sharing options...
Dandy Dave Posted March 9, 2010 Share Posted March 9, 2010 (edited) I agree, Model A Ford with an after market fan. Good catch on that packing nut. The originals were brass. The original fan was only two blades, and resembled an airplane prop. They were prone to cracking near the hub, and many were replaced. Also, the 4 bladed version moved a little more air. Dandy Dave!

Dave Henderson Posted March 9, 2010 Share Posted March 9, 2010 Dave, so true about the original fans cracking. Quite a few of them broke a blade off and it destroyed the radiator, or left a dent in the hood, or both. Sadly, this is still happening today to unsuspecting owners. Original fans are a must for judging, but can be risky for touring. '29 was the last year for the brass packing nut. Subsequent ones were of a zink alloy.

Dandy Dave Posted March 10, 2010 Share Posted March 10, 2010 Now that you mention it, I had a few of the pot metal ones myself. Thanks for the extra info. Dandy Dave! Link to comment Share on other sites More sharing options...
Dave Mellor NJ Posted March 10, 2010 Share Posted March 10, 2010 I still think it's a replacement packing nut, the originals had bigger spaced notches to tighten it with a spanner wrench. It was probably off a doodlebug to explain the red paint. Link to comment Share on other sites More sharing options...

406mac Posted March 11, 2010 Author Share Posted March 11, 2010 Thanks for information guys...OK, so what does the gear (aluminum?) on the shaft do? I have another pump that has coarser teeth on that gear..Is it some kind if accessory drive? Thanks again. Mac Link to comment Share on other sites More sharing options...
Dave Henderson Posted March 12, 2010 Share Posted March 12, 2010 That's the packing nut. It doesn't rotate with the shaft, it compresses graphite packing to seal the pump shaft. To take up for wear it is tightened in a clockwise direction. The other nut mentioned, with "coarser teeth", would be more like the original design.
