21130919 is a Mack ring and pinion gear set for the CRD 150 front differential assembly and the CRD 151 rear differential assembly. The factory parts list shows it as item 35 in the CRD 150 and item 46 in the CRD 151, where it is listed as a 15/23 T set covering 4.50, 4.80, 5.04, 5.31 and 5.66 ratios. In a drive axle the ring gear and pinion carry driveline rotation into the axle, and the differential then lets the wheels turn at different speeds through corners.
