ASSEMBLY - CONTINUED
59.
Attach dial indicator on mounting flange of differential carrier (1) so plunger is against tooth surface on drive side of
ring gear (2). Adjust dial indicator to zero.
NOTE
Move ring gear only when adjusting backlash.
60.
While holding drive pinion (3) in position, rotate ring gear (2) slightly in both directions against drive pinion teeth. Note
measurement.
NOTE
•
If same ring gear and drive pinion has been installed, adjust backlash to setting recorded in disassembly
step 5.
•
If new ring gear and drive pinion has been installed, adjust backlash to 0.01 in (0.25 mm).
61.
If backlash measurement is less than specified, loosen adjusting ring (48) on back surface of ring gear (2) and equally
tighten adjusting ring on tooth side of ring gear. Repeat step 60.
62.
If backlash measurement is more than specified, loosen adjusting ring (48) on tooth side of ring gear (2) and equally
tighten adjusting ring on back of surface of ring gear. Repeat step 60.
63.
Repeat steps 59 through 62 until backlash meets specification. Record setting for use when adjusting pinion bearing pre-
load.
NOTE
Always check tooth contact pattern on drive side of ring gear teeth.
64.
Apply Prussian blue dye to approximately 12 teeth of ring gear (2). Rotate ring gear so marked gear teeth are next to
drive pinion (3).
65.
To get contact pattern, rotate ring gear (2) forward and backward until marked gear teeth go past drive pinion (3) six
times. Repeat, if needed, for clearer pattern.
