[R-390] Removing Megacycle Change shaft

[Jacques Fortin]

Hi Barry, Paul,
Not that simple from the Y2K-3a Chapter 10.
It make things easier to have another R-390A properly assembled nearby...
I already sent some pics to Paul, if he still experiencing assembly problems, I can take more pictures from my spare (properly assembled) RF deck.

There is a document in the archives that outlines exactly how to assemble the gear train.
