Gear Housing - Stihl
Genuine Stihl gear housing for the gearbox of Stihl HS82R and HS87R hedge trimmers.
Gear Housing
Part No.
HGR1940
The Stihl Gear Housing (OEM 4237 640 0504) is a replacement housing for the gearbox on Stihl HS82R and HS87R hedge trimmers. It encloses and supports the gears that drive the cutting blades, keeping them correctly aligned and holding the lubricating grease in place.
The gear housing takes the full load of the drive and is exposed to vibration, knocks and debris during hedge cutting. A cracked, worn or damaged housing can let grease out and dirt in, leading to rapid gear wear, so replacing it helps restore smooth, reliable blade drive.

- Encloses and supports the hedge trimmer gearbox.
- Keeps the drive gears correctly aligned.
- Holds lubricating grease in and keeps dirt and debris out.
- Provides the mounting point for the cutting blade assembly.
- Replaces a cracked, worn or damaged gear housing.
