Oregon Replacement Sprocket Nose Kit 3/8" Pitch 11-Tooth for Power Match RN Bars, Includes Rivet

Oregon 30853 is a drop-in 3/8" pitch, 11-tooth replacement sprocket nose kit designed to restore the performance and extend the life of Oregon Power Match RN guide bars.

This replaceable sprocket nose is built for Oregon Power Match "RN" bars to take the brunt of wear and avoid replacing the entire guide bar. Compatible with .050", .058" and .063" gauge bars, the kit includes a hardened 11-tooth sprocket nose and the attachment rivet needed for installation. The longer nose profile on Power Match bars reduces stress on the bar body, while the replaceable design makes maintenance faster and more economical for regular users of chainsaws.

How will replacing the sprocket nose affect chain performance?

Installing a fresh sprocket nose reduces friction at the tip of the bar, helps maintain proper chain tracking, and prevents uneven wear along the rail. A new nose improves smoothness of rotation and can reduce heat build-up under load.

• 11 hardened teeth provide consistent chain engagement
• Smoother rotation lowers drag and improves cutting efficiency
• Fits Power Match RN bars to restore original geometry
• Includes rivet for secure attachment

Is this sprocket nose easy to install and what tools are required?

The kit is designed for do-it-yourself replacement with common tools, but it requires basic mechanical skill and attention to safety. You’ll remove the old nose, align the replacement, and install the included rivet—file or rivet-setting tools may be needed to finish the job correctly.

• Drop-in fit tailored for Oregon Power Match RN bars
• Includes attachment rivet to secure the nose
• Typical tools: punch, hammer, small anvil or rivet setter, file
• Follow manufacturer torque and safety guidance during reassembly
