Cute but no. Helical gears that have chips can be sanded/grinded if there are no hairline cracks. You essentially just round that part over and smooth it out taking care not sand on the face of the tooth itself using a die grinder with a 2” twist lock sanding disc. Depending entirely if any other teeth were damaged by the metal debris and if the pinion is ok. Which it sounds like It’s likely trashed. But helical gears have more than one tooth of engagement and especially being where that chip is on the inner side it’ll just roll over it.
What brand gears, still under warranty?
