Description
Overview:
The Quick Tensioning Worm Gear is a genuine Stihl OEM part that drives the quick chain tensioner mechanism on compatible Stihl chainsaws and electric/cordless saws, such as the MS 170 and MS 250. Built for longevity, it uses a durable polymer gear body with a metal insert to withstand repeated adjustments under load. Its job is to engage the tensioning mechanism so you can set accurate chain tension without tools on models with Stihl's quick tensioning system. Consistent chain tension helps reduce premature wear on the bar and chain and supports safe, efficient cutting. This replacement worm gear restores smooth, precise operation when the original gear is worn, making it suitable for both professional users and DIY owners who maintain their own saws.
Key Features:
- Genuine Stihl part for dependable fit and function
- Robust polymer gear with metal insert for durability
- Provides smooth, precise quick chain tension adjustment
- Helps maintain correct chain tension for safe cutting
- Supports bar and chain life by preventing slack or over‐tightening
- Straightforward like-for-like replacement on compatible models
- Stable engagement with the adjuster for repeatable results
- Suitable for petrol, electric, and cordless Stihl models listed
Typical Applications:
Replacing a worn or stripped quick tensioning drive gear during routine maintenance or repair. Useful when chain adjustment becomes rough, inconsistent, or slips. Ideal for workshops, arborists, landscapers, and homeowners who need reliable chain tension on Stihl saws used for pruning, firewood cutting, storm clearance, site preparation, and general property maintenance.
