[Collins] Need help with 51J Gear box.

[Bill]

I am working on a 51j-2 gear box as a favour for a fellow ham.
If anyone is willing to part with the sun/orbital gear assembly 
 (gears on the assembly which provides the detent for the band change)
please let me know. Alternatively a complete gear box either 51j-2 or
j-3/j-4.

The ones on this fellows gear box are stripped. This is the 2nd time
I've seen this.
As a heads up for folks, if the tuning/band change mechanisms are overly
stiff, don't
force them. The gear teeth are quite soft will not take the stress.

Bill, ve3jhu
