I just bought an old spoke wheel running gear that I'm going to turn into a parade wagon. This is the first of about 12 running gears I have had that has cage bearings. All the others have had tapered roller bearings. I have no experience with cage bearings. How do I repack these bearings? There are 2 bearings in each wheel and they are separated by a spacer. Are the races replaceable? I've only taken one wheel off and it appears they are adjusted by shims. The shims are held in place with a facing plate that is held on with a solid pin that is about 1/4" diameter. I haven't yet looked on google for bearings and races but first want to determine if I should invest in this relic or sell it to someone who knows what to do with it. I like the look of the spoke wheels and all appear to be in good shape except for surface rust which I can get sandblasted. Can cage bearings be driven down the road like tapered bearings? I pulled it home, about 15 miles, at 40 mph and it followed me without difficulty. Thanks for any information you can give me.
