[R-390] need help with intermittent gear aka Geneva gear

[Norman Ryan]

Hi, Phil,

It's safe to say we all feel your pain!  Have you verified that the Geneva gear has its single ball bearing inside?  There is just one of them in there.  

I don't recall if it is at all visible with or without the RF deck attached.  I would hate for you to have to take the Geneva gear apart to verify, but it likely will give peace of mind if the ball is there.  If it isn't -- well, you will know the story.

Without the ball bearing, the Geneva gear will not work right even if it and its mating gears are correctly placed.

Let us know what you find, OK?
