Description
Overview:
This Set of Pinions for Stihl FS55 and FS55C brushcutters is a genuine Stihl component designed to restore smooth, reliable drive within the tool's gear mechanism. Manufactured from hard-wearing, precision‐moulded engineering polymer for low friction and long service life, the matched pinions help transfer drive efficiently from the power unit to the cutting head. When original gears become worn, chipped, or noisy, replacing them with this OEM set helps maintain performance, reduces vibration, and protects other drivetrain parts from avoidable wear. Purpose-built for Stihl straight‐shaft trimmers in the FS55 family, the set fits correctly without modification and supports consistent cutting in grass, weeds, and light brush. Genuine Stihl part 4140 640 7300 for assured compatibility and durability.
