Oneway starter bearing is gone. It's actually called a Sprag Clutch, but it more common name is oneway bearing.

2003 Grizzly 660
30" s/w Maxxis Zilla's on Vision wheels (summer tires)
27" s/w Titan 589 on stock wheels (winter tires)
2.0 mm Primary Shim
Dalton Metallic Red Secondary Spring
High Strength Axles
Warn 2500 lbs winch
Grizzly 700 cam plate (no performance improvement, just better non-wearing slide design)

It's inside the engine cases. You will need to remove the pull cord assembly (if applicable), then remove flywheel cover/side engine cover. Then you will need to pull the flywheel. This requires a puller.

Go to any online Yamaha ATV parts website (I use parts nation). Click through to find your specific ATV year and model. Then click on starter clutch. You want item number 8, Starter One-Way Assy.
Part number: 1UY-15590-01-00
