Yamaha - Starting Motor Gear Assembly Starter System Component 6CE-81807-00-00. Overview. When a Yamaha doesn't start clean, one of the first places I look is the starter gear setup. This gear assembly is what connects the starter motor to the engine, and if it's worn, you'll hear it-grinding, slipping, or just not engaging right. I've replaced a few of these where the motor struggled to turn over, and the fix made an immediate difference. When it's working right, the engine fires up smooth and without hesitation.. Key Features. • Reliable Starter Engagement - Connects the starter motor to the engine for consistent startup.• Precision Gear Alignment - Ensures smooth meshing to reduce noise and wear during operation.• Durable Gear Construction - Built to handle repeated start cycles without premature failure.• Consistent Cranking Performance - Supports steady engine turnover for reliable starting.• Factory-Spec Fitment - Designed to match Yamaha starter systems for proper installation..
