The Eaton Fuller Thrust Washer, part number 20620, is a manual transmission internal component sold one per unit. It fits within the Manual Transmission Gear group and cross-references four OEM part numbers across two major commercial truck platforms: Mack 3088-20620 and 4333-1651333C1, and Navistar 1651333 and 1651333C1. That cross-reference coverage indicates shared Eaton Fuller manual transmission configurations across those platforms. Pro Gear and Transmission carries this as a genuine Eaton Fuller part.
