Lycoming 13S19646 Crankshaft Gear is a precision-engineered engine timing component designed for use in compatible Lycoming aircraft piston engines. The crankshaft gear transfers rotational motion from the crankshaft to the engine timing system, ensuring proper synchronization of internal engine components.

The crankshaft gear is a critical part of the engine gear train, providing accurate timing coordination between the crankshaft and driven components such as the camshaft and accessory systems. Proper gear engagement is essential for maintaining valve timing accuracy, smooth engine operation, and reliable power production.

Manufactured to Lycoming specifications, the 13S19646 crankshaft gear is designed to withstand continuous mechanical loading, vibration, and the demanding operating conditions present within aircraft piston engines. Precision-machined gear teeth provide dependable engagement and long-term durability.

The crankshaft gear should be inspected during major engine overhaul or whenever the timing system is serviced. Inspection includes checking for gear tooth wear, pitting, cracks, abnormal wear patterns, or other conditions that may affect timing accuracy and engine reliability.
