Description
Overview:
The End Cover (OEM No. 4140 121 0800) is a Genuine Stihl replacement part for the engine housing on a wide range of Stihl handheld machines. It is a robust, moulded polymer component designed to shield and close the engine end of the housing, helping to keep debris away from internal parts and sustain correct airflow around the engine assembly. This helps maintain reliable running and extends service life in day‐to‐day use. Purpose‐built for Stihl 2‐stroke equipment, it offers an accurate, secure fit with no modification required. Ideal for owners of popular brushcutters such as the FS 80 and FS 85, as well as many other Stihl trimmers, hedge trimmers, blowers, drills, Kombi engines and pole pruners listed below.
