Description
Overview:
The Gear Box Assembly 6340 640 0122 is a genuine Stihl part for self‐propelled walk‐behind lawnmowers. It transfers drive from the mower's powertrain to the wheels, helping the machine maintain steady forward motion under load.

This replacement unit restores smooth, efficient drive when the original gearbox is worn or damaged. It is intended for Stihl models such as MB 545.0 VR and MB 545.1 VR, and equivalent RM variants. Being an OEM component, it matches the original mounting points and pulley alignment for straightforward replacement and consistent performance.
