Yamaha - Transfer Drive Gear - Engine Gear Component - 6BH-17586-00-00

Overview

When power moves through the drivetrain, every gear has to stay in sync, and this transfer drive gear plays a key role in that process. It helps carry rotational force from one section of the system to another, and when it starts to wear, you’ll feel it in noise or rough operation. I’ve seen small gear wear turn into bigger internal issues if it’s left too long. Keeping this gear in good shape helps everything run smooth and dependable.

Key Features

• Power Transfer Function – Moves rotational force efficiently through the drivetrain.

• Precision Gear Teeth – Designed for smooth engagement and reduced internal wear.

• OEM Fit Accuracy – Matches Yamaha factory specs for proper alignment and function.
