Oregon Power Mate® Rim Sprocket System - .325" x 7 Tooth
The Oregon 41726XSF is a professional-grade drive system designed to provide smoother cutting and significantly reduce chain wear compared to standard spur sprockets. This two-piece system includes a high-durability splined drum and a free-floating rim that aligns itself with the guide bar groove, maximizing the life of your cutting equipment.
Cold-Forged Performance
Built using a cold-forged manufacturing process, this sprocket offers superior strength and heat resistance. The modular design allows you to replace the rim multiple times before needing to replace the entire drum unit. For peak performance, Oregon recommends replacing the rim every three chains.

🛠️ Mechanic's Tip:
This system is a popular upgrade for the Husqvarna 141 and Poulan 2900 series. When swapping from a standard spur sprocket to this rim system, always check your clutch drum needle bearing (H101310). A dry or worn bearing is the #1 cause of sprocket failure and crankshaft wear. Grease the bearing every time you have the drum off for a rim change.
