Description
Overview:
The Worm Wheel for Husqvarna 266 and 268 chainsaws is a genuine Husqvarna drive component that transfers motion to the chain oiler for consistent lubrication. Made from a durable, wear-resistant polymer with a helical gear profile, it is engineered for smooth engagement and long service life in demanding cutting conditions. This worm wheel replaces worn or damaged originals to restore reliable oil delivery and help protect the bar and chain from premature wear. Precision moulding and tight tolerances ensure correct fit and operation on compatible saws. It is suitable for professional and domestic users maintaining Husqvarna models in regular use, and is an ideal choice when carrying out routine clutch and oil pump servicing.
Key Features:
- Genuine Husqvarna part for assured compatibility and performance
- Drives the automatic oil pump for steady bar and chain lubrication
- Durable polymer construction resists wear, heat, and oil exposure
- Accurate gear form for smooth, low-noise operation
- Designed to fit correctly with the clutch drum and pump drive
- Helps prevent chain and bar damage caused by poor lubrication
- Easy to fit during routine maintenance with basic workshop tools
- Replaces worn parts to reduce downtime and keep cutting performance consistent
Typical Applications:
Used during clutch or oil pump servicing to restore the oiler drive on Husqvarna chainsaws. Ideal when the original gear is worn, stripped, or heat-damaged, causing poor or intermittent chain lubrication. Suitable for forestry, tree surgery, landscaping, and firewood work where reliable oil delivery is essential for safe, efficient cutting.
Also known as:
Oil pump drive gear, oiler worm gear, worm gear, pump drive wheel, pump pinion, lubrication drive gear for chainsaws. These terms are commonly used to describe the same component that transmits drive from the clutch area to the automatic chain oiling system.
