The existing rod assembly eye can fail on certain 631G and 637G Wheel Tractor Scrapers. If the existing rod assembly fails, the apron will not work. The new rod eye design will provide a longer shank and a larger o.d. with an increased transitional radius. This will provide more material thickness for the amount of axial load that passes through the eye around the pin. |
