The LMO has a shaft with rings on it. The rings have stops that

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.
