37-610 Half gear in front of variable capacitor slipped??
#1

I'm working on a 37-610 in a Tombstone style cabinet.   I finished all but two capacitors, I have to order more.  
I started looking over tuning and it stopped about half-way.  I look in the back and the  variable capacitor is in the right place but then I noticed this little half-gear has reached its end stop.   It shouldn't be stopping right there.   The shaft has serrations that hold this gear in place.   It's a double gear made from two then pieces of metal and there's some springs that hold them together.

So what goes here?   It must have been this way for sometime.   Considering the shaft condition it looks like should have never happened.  It was stiff, maybe someone tried to force it at one point and it skipped.
How do you properly realign this gear?
