Oregon 3/4" Pitch Harvester Pin Sprocket (14 Tooth Spline) for Fabtek 503866
Oregon 3/4" pitch pin drive sprockets for harvester machines. These sprockets are made of heat treated steel for maximum longevity. Pin sprockets works just like a chainsaw rim, supporting the chain around the circumference of the sprocket. This allows your chain to last longer, and will not wear your drivers as quickly as the spur style drive sprockets do. Simply replace pins and retainer ring when they become worn.
