MAINTENANCE MANUAL
Always check the tooth contact patterns on the
drive side of the gear teeth. Figure 5.49.
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.
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. Ad-
justthebacklashofanoldgearsettotheset-
ting 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.

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
