Description
Overview:
The Gear Housing 4230 640 0501 is a genuine Stihl OEM casing for the gear head on long‐reach hedge trimmers. Built from robust, corrosion‐resistant cast aluminium with steel fastener points, it holds the internal gears, bearings and seals in correct alignment and protects them in use. This helps maintain smooth drive to the cutter bar and reduces wear from vibration and impact. It is designed for Stihl hedge trimmers such as the HL75 and HL75K, and fits a wide range of compatible long‐reach and Kombi models. Use it to replace cracked, worn or leaking housings and to restore factory performance after heavy use or accidental damage. A direct-fit part, it supports quick, tidy maintenance using standard hand tools.
Key Features:
- Genuine Stihl part for assured compatibility and correct fit
- Durable cast aluminium body for strength with low weight
- Protects bevel gears, bearings and seals to extend service life
- Keeps gear alignment true for smooth, efficient operation
- Corrosion‐resistant finish suitable for outdoor conditions
- OEM mounting points and screw bosses for straightforward installation
- Helps reduce vibration and noise caused by a damaged housing
- Suitable for routine overhaul and like‐for‐like replacement to minimise downtime
Typical Applications:
Replacement of a cracked, stripped, corroded or oil‐leaking gear head housing on Stihl long‐reach hedge trimmers. Used during scheduled servicing, after impact damage, or when excessive play, noise or heat suggests housing wear. Suitable for professional grounds teams, landscaping contractors, estate maintenance and domestic users maintaining tall or wide hedges.
