This bushing fits inside the hydraulic cylinder assembly on a grain harvester header. It acts as a bearing surface between the cylinder rod and its mounting lug, allowing smooth pivoting during header height and tilt adjustments. A worn bushing creates play in the linkage, which can cause uneven header float and increased stress on the cylinder seals. This component is machined to match the original bore and shaft clearances, so no reaming or shimming is required during replacement.
