This chain link is a double-pitch connecting link for the gathering-chain assembly on a corn header. It joins two chain ends to form a continuous loop that drives the snapping rollers and gathering points. Wear in the link bores or side plates causes chain elongation, which leads to uneven roller timing and increased risk of chain jump or breakage. The link is manufactured to the original geometry so it maintains the correct pitch and clearance with the sprocket teeth. When replacing, inspect the sprockets for wear and confirm the chain tension is set to specification after installation.
