One New Aftermarket Replacement Worm-Circle Drive Gear Fits Caterpillar (Fits CAT) Motor Graders
This aftermarket replacement worm-circle drive gear (also cataloged as a gear worm) is a key component of the circle drive system on Fits Caterpillar motor graders. The worm gear meshes with the internal ring gear of the circle assembly, allowing the operator to rotate the moldboard and adjust blade angle during grading operations. This is a wear component in the circle drive -- Fits Caterpillar service documentation notes that the circle worm drive and worm gear should be replaced as a set when worn.
