Husqvarna OEM Spur Sprocket (.325" x 7 Tooth) for 40, 45, 49 Chainsaws 503159802

OEM Spur Sprocket from Husqvarna. Spur chain sprockets are durable, economical, simple to use, and very popular. The chain driving portion of the sprocket and the clutch cup are fused together, so when it wears out, you need to replace the whole component. The economic design makes it popular for consumer chainsaws. Spur sprockets do not come with bearings, and we recommend replacing the bearing for every two spur sprocket replacements.
