Eaton 133761 is a side pinion with 9 teeth, a 1.077 hole diameter and a 3.545 gear diameter. Our parts manual lists it as 'Pinion, Spider' in the Forward Axle and Rear Axle additional diagrams of the Dana Spicer DS404 / RS404 Tandem Drive Axle (item 18 forward, item 17 rear) and in the same two diagrams of the Dana Spicer DS405 Tandem Drive Axle. Inside a differential, the pinion meshes with the side gears so the two wheels on an axle can turn at different speeds. A genuine Eaton part from Pro Gear and Transmission.
