For many years Gilson Brothers company built fine snowblowers that featured oil impregnated bronze liner bearings in the belt tensioning idler rollers. As an upgrade to improve reliability they developed a sealed bearing upgrade kit #89400. The OEM price of this kit has skyrocketed but we have been able to control the cost of our duplicate kit that we offer direct to you. All components are new and professionally produce. Installation instructions are included.
