Yamaha Gear, Ring - Starter System Component - 67F-81891-00-00

Overview

When a Yamaha has trouble engaging during startup, the ring gear is one of those parts that can’t be overlooked. It’s what the starter gear grabs onto to turn the engine over, so if it’s worn or damaged, you’ll hear grinding or slipping right away. I’ve seen engines struggle to crank just because the teeth on this gear were worn down. When it’s in good condition, the starter engages clean and the engine fires up smoothly.
