Description
Overview:
This genuine Oregon rim sprocket is a replaceable drive rim for petrol chainsaws that run a .325-inch (8.26 mm) chain. Made from hardened steel for long service life, it sits on a 7‐spline clutch drum to transmit power smoothly from the clutch to the chain. It restores efficient cutting performance when the original rim is worn or hooked, helping to protect the bar and chain and maintain consistent chain speed. Suitable for a wide range of saws including Stihl 017 and MS 250, it is a direct-fit service part that supports reliable everyday use. Genuine Part, OEM 11892.
Key Features:
- Genuine Oregon part (OEM 11892) for assured compatibility and reliability
- .325-inch (8.26 mm) pitch to match standard .325 chains and guide bars
- 7‐spline drive interface for a secure fit on compatible clutch drums
- Hardened steel construction resists wear under continuous cutting loads
- Precision-machined rim for smooth chain drive and reduced vibration
- Direct replacement for worn rims to restore cutting efficiency
- Helps protect the clutch drum by using a replaceable sacrificial rim
- Straightforward installation with standard workshop tools
- Suitable for both professional and domestic chainsaw maintenance
Typical Applications:
Routine chainsaw servicing and repair, replacing a worn or damaged drive rim to maintain smooth chain motion and accurate cutting. Ideal for forestry, arborist work, landscaping, grounds maintenance, and firewood processing where .325-inch (8.26 mm) chain systems are used.
