This STIHL 00009581022 is a genuine OEM sprocket washer (27 mm) used in the chain drive/clutch sprocket assembly on many STIHL petrol chainsaws. It provides precise spacing and support between the sprocket, clutch drum and related components, helping to maintain correct chain alignment and smooth rotation of the drive system. Replacing a worn or missing washer ensures reliable operation and prevents premature wear of adjacent parts.
