OREGON RIM SPROCKET 3/8-7 SMALL HOLE 7 18720

This Genuine Oregon 3/8-7 SM7 drive sprocket (MPN 18720) is a steel clutch-drum sprocket designed for small-mount chainsaws. It drives the chain at a consistent speed and keeps it aligned on the bar, helping to maintain clean cuts and reduce wear on the chain and guide bar. With a 3/8 in pitch (9.53 mm) and 7-tooth configuration, it is a direct replacement for worn or damaged sprockets on many popular machines, including the Husqvarna 154 and 254. Built from durable steel with a plain metal finish, it offers reliable performance for routine servicing. Suitable for both trade and home use, it restores smooth chain movement and efficient power transfer.
