Product information & specifications
STIHL Fan Housing for MS 200, MS 200 T, 020 and 020 T Chainsaws - 1129 080 1806
The STIHL Fan Housing (part number 1129 080 1806) is a genuine OEM moulded plastic cooling shroud for the STIHL MS 200, MS 200 T, 020 and 020 T chainsaws. The fan housing surrounds the flywheel and directs cooling air across the cylinder and associated engine components during operation, maintaining correct engine temperature and helping prevent overheating under sustained cutting loads. It also provides mechanical protection around the flywheel and ignition area, shielding components from sawdust, wood chips and accidental contact. A direct replacement for cracked, warped, impact-damaged or missing housings, it aligns with the original factory mounting points for a precise, rattle-free fit.
This is the fan housing shell only — part 1129 080 1806. It does not include the rewind starter assembly. If you require the complete fan housing with rewind starter, the correct part is 1129 080 2105. Always confirm which component you need before ordering.
Key Features
- Genuine STIHL OEM fan housing — manufactured to original specification for correct fit, airflow geometry and mounting alignment
- Part number 1129 080 1806
- Housing shell only — does not include the rewind starter assembly; for the complete unit see part 1129 080 2105
- Directs cooling airflow across the cylinder — maintains correct engine operating temperature under sustained full-load cutting
- Protects flywheel and ignition area — shields components from sawdust, chips and accidental contact during cutting work
- Durable impact-resistant moulded plastic — built to withstand vibration, oil and fuel exposure, and outdoor working conditions
- Fits MS 200, MS 200 T, 020 and 020 T — covers both top-handle arborist and rear-handle variants in this STIHL platform

| Brand | STIHL |
|---|---|
| Product Type | Fan Housing / Cooling Shroud |
| Manufacturer Part Number | 1129 080 1806 |
| Material | Impact-resistant moulded plastic |
| Scope of Supply | Fan housing shell only. Rewind starter assembly not included (see part 1129 080 2105 for complete unit). |

Why the Fan Housing Matters - and Why Fit Genuine STIHL?
The fan housing does more than cosmetic work. On a small-displacement two-stroke engine like the MS 200 range — running at high RPM under sustained arborist and grounds maintenance loads — the cooling airflow path is fundamental to engine temperature management. A cracked, warped or missing housing breaks the designed airflow circuit, allowing hot air to recirculate around the cylinder rather than being expelled, increasing the risk of overheating and accelerating piston and cylinder wear. STIHL manufactures genuine OEM housings to match the original airflow specification, ensuring the designed cooling performance is maintained for the service life of the part.
Also Known As
The STIHL fan housing is also referred to as a cooling shroud, blower shroud, air shroud, flywheel cover, fan cover, engine side cover and cooling cover.
Often Replaced Alongside
- Rewind spring (1129 190 0601) — inspect for fatigue or breakage when the fan housing is removed
- Fan housing with rewind starter complete assembly (1129 080 2105) — if the rewind starter mechanism is also damaged
- Spark plug (NGK BPMR7A) — replace at standard service intervals

FAQs
Is this the complete fan housing and rewind starter assembly?
No. Part 1129 080 1806 is the fan housing shell only. If you require the complete fan housing with rewind starter included, the correct part is 1129 080 2105.
Which STIHL models does this fan housing fit?
The STIHL MS 200, MS 200 T, 020 and 020 T chainsaws. The 020 and 020 T are the predecessor models to the MS 200 and MS 200 T — same platform, renamed when STIHL transitioned to the MS series designation.
What does the fan housing do on a chainsaw?
It channels cooling air from the flywheel fan across the cylinder fins during engine operation, maintaining the designed airflow circuit and physically shielding the flywheel and ignition components.
When should the fan housing be replaced?
Replace if the housing is cracked, warped, impact-damaged or missing.
