Stihl 41407917207 Attachment Sleeve

The Stihl 41407917207 attachment sleeve serves as a critical interface component within the Stihl Kombi System, securing the connection between the drive tube shaft and interchangeable attachments such as trimmers, brushcutters, hedge trimmers, and edgers. Manufactured from high-strength engineering plastic (polyamide), it ensures precise alignment and secure locking of the attachment to the powerhead drive spline. This sleeve replaces Stihl OEM part numbers 4140-791-7207, 41407917201, and 4140-791-7201, and cross-references to aftermarket number 390-791. It features a 1-inch (25.4 mm) flange outer diameter, 0.75-inch (19 mm) inner diameter, 0.875-inch (22.2 mm) outer diameter, and an overall length of approximately 2.1875 inches (55.5 mm). The component is designed for 2-stroke engine powered equipment across the FS and KM model ranges. Regular inspection and replacement are recommended to prevent attachment wobble or disengagement during operation.
