NWP worm gears are an economical replacement option for your Husqvarna chainsaws. Worm gears (also known as pinion gears) are one of those wear items that get little attention until they quit working.

We recommend having a couple of spares around. This worm gear fits rim style (large spline) drive sprockets.
