This component is a grease fitting, angled at 45 degrees, used to deliver lubricant to a pivot point or bearing in a harvesting machine. It is installed in the lubrication port of the assembly, directing grease into the joint to reduce friction and wear. A blocked or damaged fitting prevents grease from reaching the bearing, leading to accelerated wear and eventual seizure of the pivot. The original part matches the thread and seating profile of the factory-installed port, ensuring a proper seal and reliable lubrication delivery.
