LEM #8 grinder question

I am guessing since I don't have an #8 that its the plastic wear bushing that installs on the end of the auger. If it is, its a replacement. They plastic is designed as an inexpensive wear point. All movable equipment must have one. Some are very expensive like tapered stainless steel roller bearing that are lubricated and sealed, some are inexpensive plastic or bronze wear bushings which simply wear down and are replaced as they become sloppy.

When you remove the auger assembly check the end of the shaft where the tines fit into the female end. Thats where mine goes. If its in the box, its probably like mine and a future replacement part.
