I am restoring an antique radio that has a motor driven selector. The selector mates with the variable tuning capacitor. The radio can be tuned remotely via the motor /cam assembly or manually like any other radio. The motor will drive the cams and tune the radio, however the selector mechanism is so tight the manual tuning will not operate the selector with the selector cam assembly attached. I have tries penetrating oil and lubricating the shaft of the selector mechanism with no improvement. The shaft has a gear pinned on one end and a hub pinned on the other end. I am told the pins are tapered, but I can't tell which is the smaller end to attempt to drive them out. I considered attempting to drill out, but clearances are too small for anything but a very long drill, and I'm not sure how to make sure I am drilling on the pin. The shaft is 3/8" brass, the pins appear to be steel. No one on various radio forums that I have contacted has come up with a solution. I was hopping aI might find some one on this forum who could help. If pictures coulee help, I could post some of them. Thanks for any suggestions.
