The 629588 governor bevel gear is an OEM accessory drive gear used in Continental piston aircraft engines. It transfers rotation from the accessory gear train to the propeller governor, which then controls propeller pitch to maintain selected engine RPM in constant-speed propeller systems.

It is a hardened, precision-machined bevel gear designed to mesh accurately within the accessory case gear train and operate under continuous load and lubrication.

Key features include:

OEM Continental bevel governor drive gear
Hardened steel construction
Precision-cut bevel gear teeth for stable meshing
Drives propeller governor in constant-speed systems
Maintains engine RPM via propeller pitch control
Designed for continuous-duty aviation operation
Oil-lubricated for wear and heat reduction
Installed in accessory gear train systems (model-dependent)
Used in Continental piston engine overhaul and maintenance
