Description
Overview:
This Rim Sprocket Kit 0.404 inch (10.26 mm) 7T is a genuine Stihl replacement for the chain drive system on high‐power Stihl chainsaws such as the MS 650 and 064. Made from hardened steel for wear resistance, the 7‐tooth rim is engineered to transmit power smoothly from the clutch to the saw chain. It helps maintain consistent chain speed, reduces vibration, and supports clean, efficient cutting. Designed for professional forestry, arborist, and heavy‐duty cutting tasks, it fits selected large Stihl models that run 0.404 inch pitch chain. The kit includes a precision 7‐tooth rim sprocket that sits on the clutch drum hub. Built to OEM specification for fit and alignment, it is suitable for routine maintenance or replacing a worn or hooked drive rim.
