Oregon Power Mate® Rim Sprocket System - .325" x 7 Tooth (Husqvarna)
The Oregon 29175XSF is a high-performance Power Mate® Rim System engineered for professional and frequent woodcutters. This two-piece system features a splined drum and a replaceable free-floating rim. By allowing the rim to move side-to-side on the spline, the chain remains perfectly aligned with the guide bar groove, providing a smoother cut and significantly reducing wear on both the chain and the bar.
Durability & Operational Value
Constructed using a cold-forged manufacturing process, this sprocket system is built to withstand high heat and friction. The modular design is more economical over time: you can replace the rim multiple times before the entire drum unit needs to be retired. For optimal performance, Oregon recommends replacing the rim after every three chains used.

🛠️ Mechanic's Tip:
The 29175XSF is the standard professional upgrade for the Husqvarna 55 Rancher. Because this system does not include the needle bearing, always inspect your old bearing for wear or flat spots. If it feels "gritty" when turned, replace it with Part #H131613 to prevent crankshaft damage.
