The 629602 governor gear is an OEM Continental bevel gear used in the engine governor drive system. It transmits rotational power from the engine accessory gear train to the propeller governor, which regulates propeller blade pitch by controlling oil pressure to maintain constant RPM.

This gear is a precision-machined, hardened steel component designed for accurate meshing within the accessory case gear train. It is critical for stable governor operation, ensuring the propeller maintains commanded speed under varying engine load and flight conditions.

The part is commonly referenced as a “governor driven bevel gear” in Continental engine configurations, depending on engine model and accessory case design.
