Description
Overview:
The Gearbox Cover for Stihl HS81R and HS81RC is a genuine Stihl spare part, MPN 4237 640 5800. It is a durable metal housing that shields and supports the hedge trimmer's gearbox, helping to keep moving parts protected from impact, debris, and abrasion. Designed for Stihl professional and domestic hedge trimmers, it restores correct enclosure of the gear drive after wear or damage. As a direct-fit OEM component, it matches the original cover for alignment and sealing surfaces, maintaining smooth operation and reducing unnecessary strain on the drive system. This is a practical replacement when refurbishing high-use machines or after accidental knocks that compromise the original casing.
