This 38.4-V chain link connects the sprocket segments in the header and threshing mechanism drives of the host combine. It transmits tensile load across the chain loop, maintaining the pitch length that keeps the sprocket teeth in correct engagement. A worn or stretched link causes chain skip and uneven power delivery to the intake and separating components. This replacement link is manufactured by Rollon to match the original pin and roller dimensions, so the chain pitch and clearance remain within specification. On installation, inspect the adjacent links and sprocket teeth for wear; replace any damaged components to avoid accelerated chain wear.
