Description
Overview:
The Gear Housing for Stihl brushcutters is a genuine Stihl part that protects and supports the bevel gear set at the cutting head end of the machine. Built from hard‐wearing metal with a robust cast body and machined faces, it keeps the gears correctly aligned for smooth power transfer from the drive shaft to the cutting attachment. It is designed as a direct replacement on professional Stihl models such as the FS 360 and FS 420, restoring reliable operation when the original housing is worn, damaged or cracked. The housing helps maintain cutting performance, reduces vibration caused by misalignment, and extends the service life of the gear train. OEM reference 4116 640 0512 ensures correct fit and compatibility.
