Description
Overview:
This genuine Stihl chain sprocket cover with quick tensioner (OEM Part No. 1123 640 1700) is a protective side cover for the bar and chain on Stihl petrol chainsaws. Made from tough, impact‐resistant polymer with a precision quick‐adjust mechanism, it shields the drive sprocket area from debris while allowing fast, tool‐free chain tensioning. It is engineered for the 1123 series chassis and provides a reliable fit and correct alignment on supported models, helping the saw run smoothly and safely. Ideal as a like‐for‐like replacement on well‐used machines or when a damaged cover needs changing, it restores proper retention of the guide bar and consistent chain tension. Suitable for everyday cutting tasks on popular saws such as the Stihl MS170 and MS180.
Key Features:
- Genuine Stihl part for assured compatibility and performance (OEM 1123 640 1700).
- Integrated quick tensioner for tool‐free, on‐the‐spot chain adjustments.
- Durable, impact‐resistant polymer construction for long service life.
- Accurate fit helps maintain correct bar clamping and chain tracking.

- Suitable for professional, agricultural, estate, and domestic use where frequent adjustments are needed.
Typical Applications:
Used during routine maintenance, chain swaps, and bar changes to protect the sprocket and contain debris. Ideal for jobs that need frequent chain tension adjustments, such as pruning, firewood, fencing, and light to medium timber work. Also appropriate as a direct replacement when the original cover has cracked, warped, or lost its adjustment function.
