So, lubrication fixes loosen gears? This is interesting... I don't have to worry myself anymore for that alignement and for those gears, isn't it?

No, lubrication does not fix loose gears. My advice was,

"If possible, let the motor run all the way down, then loosen the screw on the bronze gear (A) and move it slightly closer to gear B. Lubricate these gears with grease or Vaseline."

If all you did was lubricate, you might want to check the mesh of the gear teeth to be sure they're properly aligned.

Ok, George!

I'm satisfied now.
