There's no divide key. There's a lever that goes to something I can't see

Yeah, that's the conclusion I'm coming to.
The only thing you can do is 'tread carefully;. My
guess, based on
simailar machines, is that they will break down into modules, but you may
have to remvoe other small parts first. You may have to remveo individau
lcams, and they may be adustable (try to mark their postionions bfore
taking them off, I guess the service manual would have the adjustment
procedure, but if oyu had tht you'd not be asking).
I will try not to move the cams, I do not want to have to re-align them...
My inability
to disassemble them is doubly problematic since parts of the
mechanism are buried behind so much other stuff that I can't see what
they're doing, and there are parts that I can't seem to get to move using
any combination of front panel inputs... there's one bit that I've found a
way to reset (subtracting) but not a way to set using normal inputs... and
Subtracting automatically (that is, not manually) could be part of a
division mechanism? It's almost imposisble to help you without seeign
the machines (and I
don't mean seeing pictures of them), but I had a mis-spent childhood
rpairing things (inclduing doing a full ASR33 strip and rebuild without
any manuals). The tricks are to keep notes of what goes where, maybe take
photos as you go along(if you have a digital camera), and to keep
associated parts togethter (so you know where sprigns go, etc). Don't
force anything.
My guess it that you're starting in the right place, and that the ribbon
drive comes off early on. Are you sure the linkage can't be separated?
The lever that moves the ribbon holder up&down has a C-shaped bit that's
hooked all the way through the ribbon holder... it might be removable if I
move the lever rather than the ribbon holder, but it is behind a whole
bunch of other stuff. I think I will try removing the motor next, it is
close to the outside and not obviously connected to anything but the main
drive shaft.
Any idea what sort of oil I want to re-lubricate with once I get it apart
and cleaned? Light silicone oil on axles and grease on cam surfaces?
