Hoffco Comet Sprocket Clutch 1" Bore 2.5-8Hp Engine 1/4"Keyway 255-059

Stens sprockets are made with exacting specifications for direct-fit applications on chainsaws. These sprockets work in coordination with the clutch drum and motor to drive the chain with power, speed and efficiency. A new Stens sprocket provides smooth motion without any erratic movement or drag that can occur with a worn sprocket. These sprockets improve operational efficiency to ensure better cutting performance. Worn sprockets can also lead to premature wear on other chainsaw components, including the chain and bar. To prevent this avoidable wear, it’s recommended to change the sprocket after two to three chain replacements. Sprockets are moving parts that wear and need periodic replacement. Stens uses premium-quality materials and craftmanship in the manufacture of its sprockets to offer longer service life.
