This pin is a locating and pivot component within the drive system of a self-propelled forage harvester. It connects and positions a mechanical linkage or sub-assembly that transmits motion from the drive line to the working components. Wear on the pin’s contact surface introduces play in the linkage, which can cause misalignment and premature wear of the surrounding bushings or clevis. The pin is machined to the original shaft tolerance, so it fits the bore without requiring shimming or reaming during installation.
