Upgrade or restore the drive system of your mid-range professional chainsaw with this Comprehensive Rim Sprocket Conversion Kit. Specifically designed for the legendary STIHL MS 340, MS 360, 034, and 036 series, this kit provides a superior alternative to standard spur sprockets. By utilizing a floating rim system, the sprocket aligns itself perfectly with the guide bar groove, significantly reducing friction, vibration, and premature wear on your bar and chain.
This all-in-one kit includes everything needed for a complete overhaul or conversion: a high-durability splined clutch drum, a replaceable rim sprocket, a precision needle bearing for smooth idling, and the necessary clutch washer and e-clip for secure installation. Moving to a rim system not only improves cutting performance but also simplifies future maintenance—once installed, you can replace just the worn rim instead of the entire drum assembly, saving you time and money in the field.
Professional Maintenance Advantage: Using a fresh needle bearing and new hardware ensures your clutch assembly remains balanced and responsive, preventing crankshaft stress and improving the overall longevity of your powerhead.
What’s Included in the Kit
- Splined Clutch Drum: The foundation for the floating rim system, engineered for high-torque professional use.
- 7-Tooth Rim Sprocket: Provides optimal chain speed and alignment for standard 3/8" pitch chains.
- Precision Needle Bearing: Ensures the drum spins freely during idling to prevent chain creep and clutch wear.
- Clutch Washer & E-Clip: Essential factory-spec hardware for a secure and safe installation.
