199497C1 \/ 176278C2 Driven Sprocket \u2014 Corn Head Gathering Chain Replacement for Case-IH 800\u20131000 Series<\/h2>\n


\n<\/p>\n

<\/p>\n

This aftermarket driven sprocket<\/strong> (OEM reference 199497C1 \/ 176278C2) is engineered as a direct replacement for the front gathering chain sprocket on Case-IH and International corn heads in the 800, 900, and 1000 series. With a 10-tooth profile<\/strong>, 1.0-inch keyway bore, and heat-treated steel construction, it restores gathering chain tension and timing so your row units keep pulling stalks cleanly into the snapping rolls \u2014 harvest after harvest. Each kit ships with the sprocket, nut, and washer, giving you everything needed to complete the swap at the row unit.<\/p>\n

What a Driven Sprocket Does in a Corn Head Row Unit<\/h2>\n

In a corn head row unit, the gathering chain system consists of two sprockets working as a pair: the drive sprocket<\/strong> at the rear (powered by the row unit gearbox) and the driven sprocket<\/strong> at the front (the idler end that maintains chain tension and guides the chain as it returns). The driven sprocket sits at the leading tip of the row unit \u2014 the first mechanical component to contact incoming stalks. Its position directly controls how aggressively the gathering chain paddles engage the crop.<\/p>\n

When the teeth on this sprocket wear down or the bore becomes loose on the shaft, the gathering chain loses consistent tension. A slack chain skips teeth, allows stalks to escape sideways, and causes uneven wear on paddles and chain links \u2014 all of which add up to crop loss and higher per-acre repair costs. Replacing a worn driven sprocket restores the precise chain path that channels stalks reliably into the deck plates and snapping rolls.<\/p>\n

Positioned forward of the deck plates, this sprocket also acts as the first point of contact for downed or lodged corn. A correctly fitted, dimensionally accurate replacement sprocket improves your header’s ability to lift and guide those fallen stalks rather than pushing over them \u2014 reducing field losses on difficult harvest days.<\/p>\n

Why Choose Our Heavy-Duty Gathering Chain Sprockets?<\/h2>\n

OEM sprockets carry a price premium that is hard to justify on a part that wears on every acre. Our aftermarket gathering chain driven sprockets close that gap without cutting corners on the dimensions or material that matter.<\/p>\n
