This metal-rubber bushing serves as the pivot point for the threshing-unit rocker arm on a combine harvester. It sits at the hinge joint of the rocker arm, allowing the threshing mechanism to oscillate while dampening vibration transmitted through the linkage. The rubber layer bonded between the inner and outer metal sleeves absorbs shock loads from the threshing drum and prevents metal-to-metal wear at the pivot. When the rubber deteriorates or the bushing becomes oval from fatigue, the rocker arm develops free play, which leads to uneven threshing clearance and increased stress on the adjacent bearings. As an original-spec replacement from Bepco, this bushing is manufactured to the same interference fit and rubber durometer as the factory component, so it seats correctly in the rocker arm bore without requiring shimming or reaming. On installation, ensure the bushing is pressed squarely into the bore and that the rocker arm pivots freely before final assembly.
