Guest Bob Call Posted October 4, 2008 Share Posted October 4, 2008 Sounds like your packing is worn out if tightening the packing nut doesn't stop the leak. Get new packing from a supplier like Macs or Snyders and try that. Link to comment Share on other sites More sharing options...
A by the sea Posted October 4, 2008 Share Posted October 4, 2008 The Model A water pump has a compression packing. You have to occasionally (decades in time if you drive a little each year) add more. When you get a drip you use a screw driver to crank it down until it stops.Now you want to first back the nut out and make sure your shaft looks good. The shaft should be smooth. If it is all pitted up then you need to put a new shaft on or you will be having more problems soon after. Also check the bushings and bearing. Check for vertical play. There should not be much play.

Manuel Posted October 5, 2008 Share Posted October 5, 2008 They are remaking the Model A pump now with a modern bearing/seal that doesn't need any packing.I think it is called "Leakless".HTHManuel in Oz 1 Link to comment Share on other sites More sharing options...
Guest kakenk Posted October 5, 2008 Share Posted October 5, 2008 I had the same problem with my 1930 Model A. I tried tightening the packing, replacing the packing and using a "modern" bushing and packing. Nothing worked. Finally, I replaced the pump with modern style pump from Snyder's and that ended the problem. Link to comment Share on other sites More sharing options...
Guest BOBS A2 Posted June 19, 2012 Share Posted June 19, 2012 how do you change the packing? i'm trying to change the packing on my 1930 Model A. Do you just loosen off the star nut (i don't know what it's called) and then take off the old lead packing to put the new one one? Link to comment Share on other sites More sharing options...
Guest carlnut50 Posted June 20, 2012 Share Posted June 20, 2012 I use spigot packing from the hardware store. It is rope with graphite and don't cost much. Don't tighten it any more than you have to to stop the leak. Any more just wears out the shaft and packing. Those old pumps are really supposed to have a controlled leak, instead of no leak at all ever. Our culture is different today than it used to be. One drop and people get all bent out of shape.

Owen_Dyneto Posted June 20, 2012 Share Posted June 20, 2012 Agreeing totally with carlnut50. I can't quite understand all this desire to convert these old pumps to modern seals. It's only a gravity cooling system to there is no pressure to speak of on the seal. I repacked my 34 Packard with graphited cord packing about 40 years ago and in over 40,000 miles of driving have only had to adjust the packing nut 3 or 4 times. And yes, the tension of the packing nut is correct when you get the occasional drip - that's what lubricates the shaft and packing. In addition to the graphited cord packing, you can also buy preformed split rings of the same type material from several of the hobby suppliers.

FRANK 1 Posted August 7, 2019 Share Posted August 7, 2019 Can I put new packing in waterpump with out taking the pump apart Link to comment Share on other sites More sharing options...
JFranklin Posted August 7, 2019 Share Posted August 7, 2019 22 minutes ago, FRANK 1 said: Can I put new packing in waterpump with out taking the pump apart Yes, and it is best to use the packing sold by the model A vendors, Ford said not to use string faucet packing. Original packing is lead and graphite only. 1 Link to comment Share on other sites More sharing options...
