Overview
The **Lycoming Crankshaft Propeller Governor Drive Bushing (P/N LW-16354)** is a precision-machined component integral to the front section of the engine's crankshaft assembly. This vital bushing serves as a critical bearing surface for the propeller governor drive shaft, which transmits rotational energy from the crankshaft to the propeller governor. Its primary role is to ensure proper alignment, reduce friction, and provide a wear-resistant interface, thereby protecting the more expensive crankshaft from direct wear and supporting the reliable operation of the constant-speed propeller system.Specifications
