It gives you five turns of the shaft. Each stop engages the next ring and is, in turn, engaged by the previous. I can't quite visualize how that simple mechanism could be defective. Visualize what happens when two or more of the range limiting disks get frozen together by gummed up grease. I just spun an LMO from lock to lock, 521 kHz on the dial. How do you get from that to his 432? I have an LMO in my parts bin. Lemme see.... Ah-HAH! There are 6 tabs, not 5. Each ring is about 86 kHz. 521 434 347 260 173 86 The width of the tab must be about 14 kHz... seems too wide but maybe. If two of the rings are locked together, they will move as a unit and reduce the travel by one turn. Your test shows that the LMO moves about 432-434 kHz in four turns. I bet the problem is purely mechanical. Frozen ring or some such. 73 de Jim, N2EY |
