Description
Overview:
This Set of Spur Sprocket/Worm 3/8" Picco 7T is a genuine Stihl replacement set for compact professional chainsaws, including the MS200T and MS200. It combines a spur sprocket drum with a 7-tooth profile and a matching worm gear that drives the oil pump, ensuring smooth chain drive and consistent lubrication. The sprocket drum is engineered from durable steel for wear resistance, while the worm gear is a hard-wearing polymer for reliable meshing and low friction. With OEM Part No. 1129 640 2050, it restores correct power transmission from the clutch to the chain and oil pump. The 3/8" Picco pitch (3/8 in = 9.53 mm) suits low-profile chains commonly used on these saws, helping maintain cutting efficiency and extending bar and chain life.
