Starting the rebuild of the 6400. First are brakes and springs. Both top leaves of the front springs were broken but my local shop was able to fabricate replacements. Three of four brake drums are turned and all the brake shoes have new linings riveted on with a thin shim between the lining and the shoe to make them just a bit . Looks great. But one of the rear drums wobbled too much to turn. The hub itself turns about a half inch within the drum. Wheel studs are not loose at all but I found that the hub and hub flange (held on by the pressed-in wheel studs) has slipped between themselves. Looks like the hub is welded to the hub flange on the inside. Look down outside between the wheel studs, in the area between the hub flange and the drum face and you can see a triangular break in each inside weld. The other wheel has none of these little triangle break-out spots. I'm going to press out all ten wheel studs and see if it can be repaired by welding the hub flange back onto the hub, and then reinstall into the drum with new studs. Anybody seen this before? Is it repairable? Anybody know where I can source a replacement wheel and hub, just in case.
