Key features include:

OEM Continental engine idler gear
Precision-machined hardened steel construction
Used as an intermediate gear in crankshaft-driven gear trains
Maintains correct gear timing and rotational direction between components
Designed for continuous high-RPM engine operation
High fatigue and wear resistance under oil-lubricated conditions
Installed in Continental IO/TSIO engine families depending on configuration
Critical for maintaining synchronized accessory drive operation
