The Fabco sun gear, part number 478-30-5 or 478305, is a genuine Fabco drivetrain component designed for use in Fabco transfer case, PTO, and steerable drive axle assemblies. Sun gears occupy the center position in a planetary gear set, transmitting torque through the surrounding planet gears to drive the output. Fabco produces specialized transfer cases and steerable drive axle systems for heavy-duty vocational trucks, and replacement of worn or damaged internal gears with a genuine Fabco part helps maintain the integrity of those assemblies. Contact Pro Gear and Transmission to confirm this gear fits your specific Fabco unit before ordering.
