This chain link is the connecting element for the drive chain on a self-propelled forage harvester. It joins the two ends of the chain to form a continuous loop that transmits power from the gearbox output to the feed rolls and cutterhead. A worn or stretched link causes chain slip, irregular feed-roll speed, and uneven chop length. This original part is manufactured to the same pin and roller dimensions as the factory assembly, so it maintains the correct chain pitch and seating in the sprocket teeth without requiring shimming or modification. On installation, ensure the link is fully seated and the retaining clip is oriented in the direction of travel.
