[R-390] Removing Megacycle Change shaft

[rochep at comcast.net]

Thank you all so much, this is the gear I am talking about (I am holding it); doesn’t quite make it into the bushing when meshed with rear small gear of gear assembly #42. I will study Jacques pictures tonight. Yes, the document is great to show you where to put things.

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.
