3.
Check the differential carrier backlash by the following
procedure.
1)
Fix the side gear with a wedge so it cannot move
and measure the differential gear backlash with
a dial indicator on the pinion gear.
Standard value :
0 ~ 0.05 mm (0 ~ 0.002 in)
NOTE
Take the measurements at two places on the pinion
gear.
KISE610E
2)
If the backlash exceeds the limit, adjust using
side bearing spacers.
NOTE
If adjustment is impossible, replace the side gear and
pinion gear as a set.
4.
Check the tooth contact of the final drive gear by the
following procedure.
1)
Apply the same amount of machine blue slightly
to both surfaces of the drive gear teeth.
KIQE610D
2)
Insert a brass rod between the differential carrier
and the differential case, and then rotate the com-
panion flange by hand (once in the normal direc-
tion, and then once in the reverse direction) while
applying a load to the drive gear so that some
torque (approximately 25~30Nm) is applied to
the drive pinion.
KISE610G
CAUTION
If the drive gear is rotated too much, the tooth
contact pattern will become unclear and difficult
to check.

KISE650B
Increase the thickness
of the pinion height
adjusting shim, and
position the drive pinion
closer to the center of
the drive gear.
Also, for backlash
adjustment, reposition
the drive gear further
from the drive pinion.

3. Toe contact

4. Flank contact
KISE650D
Decrease the thickness
of the pinion height
adjusting shim, and
position the drive pinion
further from the center
of the drive gear.
Also, for backlash
adjustment, reposition
the drive gear closer to
the drive pinion.
KISE630B
NOTE
•
Tooth contact pattern is a method for judging the
result of the adjustment of drive pinion height and
final drive gear backlash. The adjustment of drive
pinion height and final drive gear backlash should
be repeated until the tooth contact patterns are
similar to the standard tooth contact pattern.
•
When you cannot obtain a correct pattern, the
drive gear and drive pinion have exceeded their
limits. Both gears should be replaced as a set.

5.
Check the oil leaks and the lip part for chew or wear.
6.
Check the bearings for wear or discoloration.
7.
Check the gear carrier for cracks.
8.
Check the drive pinion and drive gear for wear or
cracks.
9.
Check the side gears, pinion gears and pinion shaft
for wear or damage.
10. Check the side gear spline for wear or damage.
