Description
Overview:
The Spur Gear for Stihl HL90K and HL95 hedge trimmers is a genuine Stihl replacement part designed to keep the gear head running smoothly. Made from precision‐machined metal, this gear sits within the drive system to transmit power reliably to the cutting mechanism, helping maintain clean, consistent trimming performance. As an OEM component, it matches the original specification for fit and function and is identified by MPN 4230 640 7503. Replacing a worn or damaged spur gear helps reduce noise, vibration, and premature wear elsewhere in the gearbox. Suitable for a wide range of Stihl long‐reach and KombiSystem hedge trimmer heads, it is a practical choice for routine maintenance and repairs in professional and domestic settings.
Key Features:
- Genuine Stihl OEM part for assured compatibility and performance
- Precision‐cut metal construction for strength and long service life
- Correct tooth profile to ensure smooth, quiet meshing and efficient power transfer
- Restores drive integrity in the gear head to support clean, accurate cutting

- Clearly identified by Stihl MPN 4230 640 7503 for easy cross‐checking
Typical Applications:
