Description
Overview:
This Genuine Stihl chain sprocket is a drive cog for compact petrol chainsaws such as the MS192C and MS170. It uses the 1/4 in (6.35 mm) Picco pitch with an 8-tooth profile to transfer power from the clutch to the guide bar and chain. Built from hardened steel, it is designed to withstand the abrasion and load cycles seen in everyday cutting. Replacing a worn sprocket helps keep chain motion smooth, reduces wear on the chain and bar, and maintains cutting performance. The form and tooth profile are engineered for a precise fit on compatible Stihl machines, making it a dependable service part for routine maintenance or repairs.
Key Features:
- Genuine Stihl part for assured fit, specification, and reliability
- 1/4 in (6.35 mm) Picco pitch with 8-tooth spur profile for steady chain feed
- Hardened steel construction for durability and wear resistance
- Precise machining helps maintain chain alignment and reduce vibration
- Supports efficient cutting and helps limit chain and bar wear
- Straightforward to fit during routine service with standard tools
- Suitable for a wide range of compact Stihl chainsaws (see model list)

Typical Applications:
Used during maintenance or overhaul when the existing sprocket shows hooked teeth, uneven wear, or chain jump.
