Pulling the affected gear out is a breeze. Just remove the brass spacer sleeve outfirst BEFORE pulling the smallgear apart from the larger gear. A 2 part epoxy is much more cleanerway ofgluing than CA. Sand both sides, apply the epoxy to both gears and press the gear back in. Once it's set, re-install the spacer from the small gear side and then place back into the elevation unit.

Easy peasy, lemon squeezie.
