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.

Key Features:
- Genuine Stihl OEM part for assured compatibility and fit (MPN 4237 640 5800)
- Strong metal construction for reliable protection of internal gears
- Direct replacement for the original cover to maintain correct alignment
- Helps preserve gearbox performance and extend service life of the tool
- Suitable for regular use in demanding garden and site conditions
- Straightforward installation using the machine's existing fixings
- Built to Stihl standards for durability and long-term reliability
- Supports smooth drive operation by keeping debris away from moving parts

Typical Applications:
Used when the existing gearbox cover is cracked, worn, or bent from impact. Ideal during routine servicing, rebuilds, or after heavy trimming work where the gear housing has taken knocks. Suitable for professional contractors, grounds teams, and homeowners maintaining hedges and shrubs, helping keep Stihl hedge trimmers running dependably between services.

Also known as:
Gearbox lid, gear housing cover, gear case cover.
