Original Note:
The shape of gear teeth is engineered and carefully controlled, therefore unlikely to be arrived at with hand-filing. Cast aluminum has inferior strength and wear properties (galling) compared with steel. The "repair" will be short-lived under load. https://en.wikipedia.org/wiki/Gear https://en.wikipedia.org/wiki/Galling
