PART NUMBER Examples The following are part numbers for generoid gear sets. • 36786-K or 36786-K2 for the ring gear • 36787-K or 36787-K2 for the drive pinion In the following procedures, movement of the contact pattern along the length of the tooth is indicated as toward the heel or toe of the ring gear. Figure 5.48. TALÓN PART NUMBER OPTION Always check the tooth contact patterns on the drive side of the gear teeth. Figure 5.49. MAINTENANCE MANUAL TIP PART NUMBER Figure 5.47 Figure 5.48 Assembly and Installation DRIVE SIDE CONVEX Figure 5.49 1.Adjust the backlash of a new gear set to either 0.012-inch (0.305 mm) or 0.015-inch (0.380 mm) depending on the size of the ring gear. Adjust the backlash of an old gear set to the setting that was measured before the differential was disassembled. See the procedure in this section. 2. Apply a marking compound in approximately 12 gear teeth of the ring gear. Rotate the ring gear so that the 12 gear teeth are next to the drive pinion. Figure 5.50. Figure 5.50 3. Rotate the ring gear forward and backward so that the 12 gear teeth go past the drive pinion six times to get the contact pattern. Repeat, if needed, to get a more clear pattern 59
Assembly and Installation 4. Look at the contact patterns on the ring gear teeth. Compare the patterns to Figure 5.51, Figure 5.52 and Figure 5.53. The location of a good hand-rolled contact pattern for a new gear set is toward the toe of the gear tooth and in the center between the top and bottom of the tooth When the differential is operated, a good pattern will extend approximately the full length of the gear tooth. The top of the pattern will be near the top of the gear tooth. Figure5.54. The location of a good hand-rolled contact pattern for an old gear set must match the wear pattern in the ring gear. The new contact pattern will be smaller in area than the old wear pattern. A high contact pattern indicates that the drive pinion was not installed deep enough. A low contact pattern indicates that the drive pinion was installed too deep in the differential case. • If the contact pattern requires adjustment, continue by following Step 5 to move the contact patterns between the top and bottom of the gear teeth. • If the contact patterns are in the center of the gear teeth: Continue by following Step 6.
