The extreme temperatures on roads here in Chicago are legendary. We were working with a piece of equipment that rode low to the asphalt during these extreme temperatures. We began losing the gear-boxes that sat closest to the road. The oil inside was cooking and the boxes were burning out. Leahy-Wolf actually put this on the drawing board and brought us a “best-value” solution. They innovated a silicone lubricant that not only does the trick and keeps our pavers in business, but it’s completely price competitive.
