Description
Overview:
This Worm Gear .325" for Husqvarna chainsaws is a genuine Husqvarna component engineered to drive the oil pump and keep your saw running smoothly. Built from hard‐wearing polymer for low friction and long service life, it transfers rotation reliably from the clutch assembly to the oiler mechanism. The .325 in pitch (approximately 8.25 mm) matches saws set up for .325‐pitch cutting systems. Designed for a precise fit in the Husqvarna 350 and 340 series, it maintains correct alignment and efficient power transfer inside the clutch side of the saw. As an OEM part, it supports consistent chain lubrication, reduces wear on mating parts, and helps restore performance when the original gear is worn, glazed, or stripped.
Key Features:
- Genuine Husqvarna part for assured compatibility and performance
- Matches .325 in pitch (about 8.25 mm) systems used on compatible models
