I am in the process of going thru my steering gear box on my 47 8N. Just received my parts from YT and I noticed a hard felt material on the bottom side of the bearing that is not on the bearing I took out. This is the bearing on the end of the tube right below the steering wheel. Does anybody know what this is for? It looks like it was intended to be there but I do not know the purpose. It is right on the end of the "cup" or the portion of the bearing that gets pressed into the tube and just above this ring that looks like it holds the bearing together. The diameter of it is smaller than the "cup". If this is some kind of seal, what is it sealing? Any feed back would be greatly appreciated.
