💡 RECOMMENDED PAIRING:
Don’t use a rounded or rusted nut with a brand new washer. Ensure the best grip and easiest future maintenance by grabbing the matching nut. View the Engine Sprocket Nut here.

🔧 Install Tips

Clean the Splines: Before fitting, wipe the output shaft splines to ensure the washer sits perfectly flush against the sprocket.
Bend the Tab: Once the sprocket nut is torqued to spec, use a flat-head screwdriver or pliers to fold one side of the washer firmly against the flat side of the nut.
Check Slack: Always aim for 20–30mm of chain slack; a chain that is too tight puts unnecessary pressure on this washer and your gearbox bearings.
