Yamaha - Drive Gear - Engine Drivetrain Component - 60R-E1536-00-00

Overview

This is one of those internal gears that keeps everything in sync when the engine is running. It’s constantly transferring motion and load, so it needs to stay tight and true under pressure. When it’s in good shape, the engine runs smooth and quiet. When it starts to wear, you’ll hear it or feel it pretty quickly, especially under load.
