This genuine Stihl chain sprocket cover (OEM No. 1142 640 1705) is designed for the Stihl MS 500i chainsaw. It helps shield the drive sprocket and chain area from impact, debris, and everyday wear while providing a precise OEM fit. The cover supports proper alignment of the guide bar, chain, and chain tensioning components and is designed to interface correctly with the saw's existing chain brake system. Built for regular exposure to oil, wood chips, and cleaning, this genuine Stihl replacement part is well suited for demanding forestry, arborist, and general outdoor applications.
