Default GE Super Radio III Tuner Re-Thread?

Hi -

Does anyone have any pictures or diagrams of how to re-thread the GE
Super Radio III vernier? The Service Manual doesn't discuss it.

I knocked mine loose while fixing my radio. I had a problem last year
at this time where after a half hour of use, the radio would slowly
tune tself across the band like an invisible hand was turning the dial.

I tried to diagnose it, but the problem went away and didn't return
after hit the tuning pot at R2 with freeze spray.

I was OK for about a year, until it re-occurred this summer. I hit R2
with the freeze spray again, and the problem would only go away
momentarily. I looked at the bottom of the circuit board and it
appeared quite dirty with flux. I theorized that in humid weather the
rosin was affecting the circuit. I cleaned the PCB around R2,
accidentally knocking off the tuning wheel. Now the problem seems
fixed but I can't get everything back together as I didn't take notes,
never intending to remove the tuning wheel and thread.

I think the string threads around spools 1,2,3,Loop Capstan Twice?,4,5
and then I can't quite figure out how to thread from 5 to the spring or
hook on the wheel and from the spring or hook eventually to spool 6.

1 ------------------ Vernier ----------------------------- 2

6 ------------- Spring \ 3
Wheel "D" slot at R2 \ |
Hook \ Capstan Loops?

I'd be grateful if anyone with a GE Super Radio III and a hand mirror
could describe or show how to re-thread the vernier through the spools,
capstan, and tuning wheel.
