Description
Overview:
The Fan Housing (MPN 1139 080 1803) is a genuine Stihl OEM cover designed for compact Stihl chainsaws, including the MS 181 C and MS 211 C. Moulded from high‐impact, heat‐resistant polymer, it encloses the flywheel area and directs cooling air across the cylinder and muffler, helping the engine maintain the correct operating temperature. It also shields internal components from chips, dust and accidental knocks during everyday cutting work. A sound housing is important for safe operation and reliable cooling, especially on saws that see regular use. This genuine part matches factory mounting points for a straightforward replacement using the existing fixings, making it well suited for routine maintenance or to replace a cracked, warped or missing housing.
Key Features:
- Genuine Stihl OEM part for assured compatibility and fit
- Durable, impact‐ and heat‐resistant polymer construction for long service life
- Helps maintain correct airflow to prevent overheating and performance loss
- Shields the flywheel and adjacent components from debris and minor impacts
- Accurate moulding aligns with factory vents and mounting bosses

- Stihl reference: 1139 080 1803 for easy identification and ordering
Typical Applications:
Replacement during servicing or repairs on Stihl chainsaws that show cracked plastics, broken vents, heat damage or poor cooling performance. Useful after impacts, heavy forestry or landscaping work, and when restoring saws to safe working condition. Suitable for routine maintenance to keep airflow paths clear for consistent engine temperature and reliability in domestic, trade and hire fleet settings.
