VIBRATION DAMPER
Inspect the vibration damper seal for damage and/or excess

Fit the complete final drive assembly to the wheel, turn the
rear chain sprocket manually in both directions and check
clearance between vibration damper seal and hub. Change
the vibration damper seal if you find exceeding clearance.

and replace the both sprockets and chain if exceedingly
worn, see (REMOVING THE FINAL DRIVE ASSEMBLY)
