This metal-rubber bushing mounts in the straw-walker assembly of a combine harvester. It acts as a vibration-damping pivot point between the walker frame and the drive linkage, reducing metal-to-metal wear and noise. A worn bushing allows excessive play in the walker motion, which can lead to uneven crop separation and increased stress on the drive components. This original part is manufactured to the same material bond and dimensional tolerance as the factory-installed bushing, so it seats correctly in the walker bore without modification. On replacement, ensure the bore is clean and free of debris before pressing the bushing into place.
