This chain half link is a single-pitch section used to repair or extend the feeder-house conveyor chain on a combine harvester. It connects two ends of the chain to form a closed loop, allowing the chain to be shortened or lengthened without replacing the entire assembly. The link is an original manufacturer component, so its pin and roller diameters match the factory chain’s pitch geometry, ensuring proper engagement with the drive sprocket and idler wheels. A worn or stretched chain causes slapping and uneven feeding of crop material into the threshing drum; replacing the damaged section with a half link restores correct chain tension and alignment. When installing, ensure the link’s side plates seat fully in the chain’s outer plates and that the retaining clip is oriented to face the direction of travel.
