Description
Overview:
The Gear Housing 500mm for Stihl hedgetrimmers is a replacement outer casing that supports and protects the drive gears and shaft at the cutting end. Built with a robust metal construction for long service life, it keeps the gear train aligned to maintain smooth operation and clean cuts. It is designed for professional and domestic Stihl long‐reach hedgetrimmers, including HL 145 and HLA 135 models. The overall length is 500 mm (19.7 inches), matching the original specification so the cutting head and drive components sit correctly. This housing is suitable when the original casing is cracked, worn, or distorted after impact or heavy use. Identifying numbers include OEM ref. 4243 640 0513 and MPN 42436400513, helping you confirm compatibility before fitting.
