Harvester Rim Drive Sprocket, .404 in. Pitch, 20mm Bore, 12-tooth, Type B

Oregon rim style harvester drive sprockets are made from high quality heat treated steel. These drive sprockets are specifically designed to fit the hydraulic motors on harvester machines. The new XL design comes complete with patented wear marks, so you know when the sprocket needs to be replaced. Chip ejection port design allows the sprocket to be mounted from either side. Oregon .404 pitch drive sprockets are designed to work with 18HX, and 19HX harvester chain, but they will fit any .404 pitch chain, and sprocket teeth slots accept both .063 1.6mm and .080 2.0mm gauge chain. Bore: .787 20mm, Diameter: 2-3/4 71mm, Width: 1/2 12mm. All harvester chain is intended for use on mechanized harvesting equipment only and should never be used on hand-held chainsaws.
