Spinneyhill Posted April 17, 2015 Share Posted April 17, 2015 (edited) I am overhauling the water pump in my 1930 Dodge DC-8. I have made a new shaft from silver steel and new bushes - outer is bronze, the inner is "oilite". Lubrication is by oil at both bushes. I am overhauling it because water was coming out of the rear bush oiler.There is a gland packing in front of the inner bush. What should be on the inside, between the impeller and the housing (which is flush with the inner end of the bush)? I believe it is called a "packless" seal and have seen references to carbon. I have also seen this diagram at http://airconditioningmanuals.tpub.com/TM-750-254/TM-750-2540026.htm showing a seal of some kind with a spring between it and the impeller.
