Description
Overview:
This Set of Spur Sprocket/Worm 1/4" Picco 8t is a genuine Stihl replacement for the chain drive and oil pump drive on compact pro saws such as the MS 201 and MS 201 C. It pairs a hardened steel spur drive sprocket (1/4 inch / 6.35 mm Picco, 8-tooth) with a durable polymer worm gear that drives the oil pump. Working together, they keep the chain correctly engaged and the bar reliably lubricated, supporting smooth cutting and helping to limit premature wear to the bar and chain. Built to Stihl's OEM specification, the set fits accurately on the clutch side for straightforward servicing and consistent performance. It's a practical choice for arborists, grounds teams, and homeowners maintaining MS 201-series saws.
Key Features:
- Genuine Stihl OEM component set for assured fit and compatibility
- 1/4" (6.35 mm) Picco 8-tooth spur drive for correct chain pitch engagement
- Matching worm gear restores positive oil pump drive and steady lubrication
- Robust steel sprocket and wear-resistant polymer worm for long service life

- Supplied as a matched pair to refresh both drive and pump functions in one service
Typical Applications:
