Hallicrafters SX-28 owners may be interested in this article about restoring the SX-28 tuning gearbox: http://antiqueradio.org/SX-28Gearbox.htm Thanks to Doug Moore for writing this detailed saga, and to Hallicrafters Collectors International for giving permission to mirror it on my website. Excellent article......I hope I never have to actually do this! Incidentally, I've discovered a pretty good way to remove those C rings. There are several of them on the gear train of a direlict Hammarlund SP-600 I'm restoring now. Description follows: Get two pairs of small needlenose pliers. Ideally, these should be the kind that are somewhat flat on the ends rather than pointy. Orient the C ring so that each end of the "C" is pointed towards the bottom (like an inverted U) Position the first pair of needlenose so that one tip is resting on the end of the shaft, toward the top, and the other tip is resting on the left end of the C ring. Position the second pair of needlenose so that one tip is resting on the end of the shaft, toward the top, and the other tip is resting on the right end of the C ring. Now, carefully apply a gentle squeezing to the handles of both pairs of needlenose pliers simultaneously, and the C ring will begin to spread. When it is about halfway off, you can then insert a small screwdriver and gently pry the C ring the rest of the way off. Be careful not to score the shaft. To re-install a C ring you have removed, simply place the spread-open C ring back on the shaft, and then take a pair of long nose pliers and squeeze the edges of the ring until it closes as much as it can on the shaft.
