Overview
The Lycoming Crankshaft Gear Bolt (P/N LW-14733) is a critical fastening component within the engine's power transmission system. This specialized bolt is engineered to securely attach the crankshaft gear to the crankshaft, forming an integral link in the engine's timing mechanism. The crankshaft gear is responsible for driving the camshaft, which in turn operates the valve train, and also provides the drive for various engine accessories such as magnetos, the oil pump, and the fuel pump. The integrity of the P/N LW-14733 bolt is paramount for maintaining precise engine timing and reliable operation, as its failure could lead to catastrophic engine damage.Specifications
