Description
Overview:
This Gear Housing is a genuine Stihl OEM replacement for petrol hedge trimmers, designed to protect and support the drive gears at the cutter head. Built from robust metal alloy for strength and good heat dissipation, it keeps the gear train correctly aligned and shielded from impact and debris, helping your machine run smoothly and cut cleanly. It is made for Stihl hedge trimmers, including the HS81T and HS86T, and matches OEM No. 4237 640 0500 for straightforward identification. A sound housing reduces vibration, supports bearings and seals, and extends the life of the pinion and cutter gears during regular trimming work. Suitable for professional users and homeowners, it is a practical replacement when the original casing is worn, cracked, or corroded.

- Genuine Stihl part for assured compatibility and fit (OEM No. 4237 640 0500).
