Description
Overview:
The Worm (Later Type) for Stihl chainsaws is a genuine Stihl drive gear that transfers motion from the clutch to the oil pump, helping to keep the bar and chain correctly lubricated during cutting. Made from a hard‐wearing polymer designed for long service life, it replaces worn or stripped worm gears to restore smooth, reliable oil delivery. This later-type worm is built for precise fitment in Stihl professional and homeowner saws and is a direct replacement on models including the MS240 and MS261. Correct lubrication reduces chain wear and overheating, so keeping this part in good condition is important for safe operation, cutting performance, and extending the life of your saw's bar and chain.
Key Features:
- Genuine OEM Stihl part for assured compatibility and performance
- Later-type design for the correct fit on specified models
- Durable polymer construction resists wear from everyday use
- Restores reliable oil pump drive to maintain bar and chain lubrication
- Helps prevent premature bar and chain wear and overheating
- Precise dimensions for easy, accurate installation
- Suitable for routine servicing and cost‐effective repairs
- Supports consistent cutting performance and tool longevity
Typical Applications:
Used during servicing or repair when the chainsaw's bar and chain are not oiling correctly, when the original worm gear shows wear, or after clutch and oil pump maintenance. Suitable for professional forestry, arborist work, landscaping, and DIY tasks where reliable chain lubrication is essential for efficient cutting and reduced component wear.
