Oregon .325 Spur Sprocket 100876X 7 Tooth – For Stihl 026, 027, MS260, MS270, MS280

Oregon spur sprocket. Check the sprocket regularly for wear. Grooves get worn into the drive teeth and over time these can become excessive which then leads to damage to the chain drive links. This then causes rapid widening of the guidebar groove. Sprockets are the most neglected wear item.
