Description
Overview:
This Chain Sprocket Cover is a genuine Stihl part designed for professional petrol chainsaws, including the MS651 and MS661. It forms the outer guard over the clutch and sprocket area, helping to protect critical drive components from knocks, sap, and debris while the saw is in use. The cover also clamps the guide bar securely to the powerhead using the existing bar studs and nuts on the saw. Built with a hard‐wearing, impact‐resistant construction and a clean white finish, it provides a precise OEM fit that helps maintain smooth chain running and reliable chip clearance. Supplied to Stihl specification under OEM No. 1144 640 1700, it is a direct replacement for worn, cracked, or damaged covers on MS651, MS661, and MS661C models.
