Description
Overview:
The Worm 3/8'' Picco 6T is a genuine Stihl drive component for compact professional and homeowner chainsaws, including the MS200T and MS200. It is a precision‐machined gear designed to transmit drive from the clutch area to the chain system for smooth, consistent chain movement under load. Built from durable, wear‐resistant metal, it stands up to regular cutting and frequent stop‐start use. With a 3/8 inch (9.53 mm) Picco pitch and a 6‐tooth profile, it provides the correct engagement and chain speed for saws specified for 3/8 P setups. This OEM part helps restore performance when the original gear shows wear, reduces the risk of slippage, and supports reliable cutting in pruning, arborist work, and general property maintenance.
