Description
Overview:
The Chain Sprocket 3/8" Picco 7Z is a genuine Stihl drive component for compact petrol chainsaws such as the MS 192 C and MS 192 T. Made from hardened steel, it transmits engine power to the chain with consistent accuracy. The 3/8 inch (9.53 mm) Picco pitch and 7-tooth profile match low‐profile cutting chains for smooth running and clean drive engagement. As a routine wear part, a fresh sprocket restores cutting efficiency, helps prevent chain skip, and reduces premature wear on the bar and chain. Built to Stihl specifications, it fits correctly and runs true, supporting reliable performance in pruning, limbing, and general property maintenance.
