This lubricating line delivers grease or oil to the bearings and bushings within the threshing mechanism of the parent combine. It is routed from the central lubrication point to the specific rotating components that require periodic lubrication during operation. A restricted or broken line starves the bearing assembly, leading to overheating and premature failure. This original component is formed to the same routing path and end-fitting geometry as the original assembly, ensuring it clears adjacent moving parts without chafing.
