Description
This small piece of stamped metal plays a massive role in keeping your GV300S final drive safe. The front engine sprocket deals with huge amounts of pulling power and constant engine vibration. This tab washer acts as a solid mechanical lock to stop the main shaft nut from spinning itself loose. Whenever you put a fresh chain and sprocket kit on your bike, using a new lock washer is a smart, low-cost habit that avoids major gearbox damage on everyday roads.

🔧 Install Tips
- Use a Torque Wrench: Never guess how tight your sprocket nut is. Use a proper torque wrench and tighten the nut to the exact settings listed in your workshop manual.
- Fold the Edge: Once your sprocket nut is fully torqued home, use a flat screwdriver and a small mallet to gently bend one outer edge of the tab washer up and flat against a side face of the nut.
- Clean the Threads: Wipe away old sticky chain grease and road grit from the gearbox shaft threads before putting the new hardware on. This makes sure your wrench readings are accurate.
- Manufacturer Reference Cross-Match: Directly replaces original production factory record number 09167H20002JS.
