[R-390] R-390A gear train

[Roger Ruszkowski]

Bob,
 
I think you are over thinking this problem.
 
Pull it all apart and have some fun and get it clean.
 
As you put it back together do not worry about alignment.
 
Worry about getting split gears properly loaded.
worry that gears run well in plane with each other and do not fall off the side of it mate.
worry that clamps are well centered.
 
 Then when you get it all back together and it runs end to end,
Center the zero adjust range first.
Then set the dial counter
Then do the mechanical alignment of the cams to the cam marks.
Then get the time-ing on the band switch gear set.
Then get the band switch well adjusted.
Then get the Osc deck switch well adjusted.
Then make sure you can get a spline driver into ever clamp in the gear 
train while it is setting at the mechanical alignment point.
Pick and choose where you put the spline bolts back in.
Put the best ones in the cam clamps.
Put the worn ones in the fixed gears.
Put the middle one sin the split gear clamps.

Now do a complete mechanical alignment of the gear train before
putting the cans and slug racks back in.

There is no need to mark everything as you pull it apart.
You are going to have to adjust and readjust it all as you put it back together.
It need not go back together tooth to tooth or even clamp to gear or cam.

You will want to rearrange some of the small parts to help with future maintenance.
