[Boatanchors] Disassembly of Vernier Drive Used in Ranger and Valiant Transmitters

[Roger Shultz]

Hi Mike,

I had a couple of those with the same exact problem and in one case I did
disassemble it, cleaned it, then re-lubed it but with no improvement.

As I recall, the large brass nut unscrews from the brass body but my memory
is too vague otherwise to provide more specifics. 

I was never able to determine why the "flatness" occurred even after
inspecting the balls and the channels they rode in. I hope you have better
luck.

How do I disassemble the vernier drive assembly from a Ranger/Valiant 
transmitter?

I have two of these drives and both are very stiff and I can feel 
"detents" caused by the (dry?) ball bearings inside the unit.  I'd like 
to take them apart, clean and re-lube them, but I haven't figured out 
how to get them open.

Thanks!
