Description
Overview:
The genuine Stihl annular buffer (OEM No. 1145 790 9903) is a moulded elastomer vibration damper used in the anti‐vibration system of Stihl chainsaws. Positioned between the engine unit and the handle assembly, it isolates engine vibrations to improve comfort, control and cut consistency during extended use. Made from durable, fuel‐ and oil‐resistant rubber, it withstands harsh site conditions and regular exposure to chain oil and sap. Designed for professional compact saws such as the MS 201 TC‐M and MS 201, it helps reduce transmitted vibration, protects surrounding components from fatigue and maintains the correct geometry of the saw's handle frame. As a direct replacement to Stihl's original specification, this Genuine Part restores factory damping performance and fits without modification for reliable, repeatable results.
Key Features:
- Genuine Stihl part (OEM 1145 790 9903) for assured compatibility and performance
- Tough, fuel‐ and oil‐resistant elastomer for long service life in demanding conditions
- Restores anti‐vibration system efficiency to help lower felt vibration at the handles
- Supports steadier control and cleaner cuts during pruning, limbing and felling work
- Helps maintain alignment of engine and handle assemblies, reducing stress on mounts and fasteners
- Consistent hardness to OEM spec for effective isolation without excessive movement
- Straightforward fit with standard workshop tools; no modifications required
- Ideal when existing buffers show cracking, softening, tearing or increased vibration
Typical Applications:
Used during routine maintenance or repairs when the saw shows increased vibration, handle buzz or visible damage to existing buffers. Common in arboriculture, landscaping and grounds maintenance for tasks such as pruning, crown reduction, dismantling, logging and snedding. Beneficial for operators who run MS 201‐series saws for long periods and need reliable vibration control.
