The 655422 is an engine camshaft drive gear used in Continental aircraft piston engines. It transmits rotational motion from the engine gear train to the camshaft, ensuring correct valve timing for intake and exhaust cycles.

Key features include:

OEM Continental camshaft drive gear
Precision-cut hardened steel gear construction
Synchronizes crankshaft rotation with camshaft timing
Controls valve opening/closing events via camshaft actuation
Designed for continuous high-RPM engine operation
Oil-lubricated gear interface for reduced wear
High fatigue resistance under cyclic engine loads
Used in Continental IO/TSIO engine families (application-dependent IPC configuration)
FAA-certified engine timing system component
