Maintain the health of your bar and chain with the Genuine Husqvarna Oil Pump Pinion. Also known as the worm gear, this precision-engineered component drives the oil pump to ensure consistent lubrication during high-RPM operation. As an OEM Husqvarna part, it offers the exact fit and heat resistance required for professional-grade timber harvesting and heavy-duty bucking.
This pinion gear is designed specifically for the Husqvarna 365 and 372 XP families, including the modern X-TORQ models. It is also the direct factory replacement for Jonsered and RedMax equivalents. Replacing a worn or stripped worm gear is essential to prevent oiler failure, which can lead to catastrophic damage to your guide bar and saw engine.
