The 654741 Accessory Drive Gear is a precision-machined OEM gear used in Continental aircraft piston engine accessory drive systems. It is part of the engine’s accessory gear train, transmitting mechanical power from the crankshaft to various engine-driven accessories such as magnetos, oil pumps, and fuel system components. The gear is designed to maintain accurate timing, stable torque transfer, and long-term durability under continuous high-load aviation engine operation.

Key features include:

Genuine Continental OEM accessory drive gear
Hardened, precision-ground steel construction
Designed for accurate torque transmission in accessory gear train
Ensures synchronized operation of engine-driven accessories
High wear resistance under continuous cyclic loading
Optimized tooth geometry for smooth meshing and reduced backlash
Oil-lubricated operation for reduced friction and heat
FAA-certified component for Continental piston engine assemblies
Commonly used in engine accessory sections (oil pump / magneto / accessory drive systems depending on engine model)
Designed for long service life under high-RPM aviation conditions
