Description
Overview:
This genuine Stihl chain sprocket is a direct replacement for worn or damaged sprockets on mid-range Stihl chainsaws, including the MS 250 and MS 250 C. Made from durable, wear-resistant steel, it transfers power from the clutch to the saw chain, keeping chain movement smooth and cutting performance consistent. The sprocket has a 0.325 inch (8.26 mm) pitch with 7 teeth, matching Stihl chains of the same pitch for correct engagement and reduced wear on the bar and chain. Built to Stihl's OEM specification (1123 640 2074), it offers an accurate fit and reliable operation for regular maintenance or refurbishment. Suitable for professional users and DIY owners alike, it helps restore cutting efficiency and extends the service life of your saw when paired with a correctly matched chain.
