Gear Set Identification

^ The trademark shows the company logo, and identifies the location of the manufacturing facility.

^ CAUTION: Never mate a differential ring gear and pinion together that does not have the same matched set numbers. Always install a new matched set if discarding either the differential ring gear or the pinion.

A corresponding number marked on the differential ring gear and pinion identifies them as a matched set.
^ The manufacturer's date identifies the gear set's date of fabrication.
^ The tooth combination identifies the number of teeth on the pinion and the number of teeth on the differential ring gear. A tooth combination of 41-11, for example, would indicate that the pinion has 11 teeth and the ring gear has 41 teeth that results in a 3.73:1 ratio.
