b. When rechecking the preload by
using Socket Wrench (499987100)
and beam type torque wrench,
observe whether the starting. fric-
tion torque is within the following
range.
NOTE:
1.23 - 1.62 N'm
(12.5 - 16.5 kg-cm,
10.9 - 14.3 in-Ib)
Before measuring preload, insert Shaft
(398653600) into the splined end of
the reduction drive gear, and install
Handle (899924100) to give the shaft
2 or 3 turns.
After rechecking the preload, stake
the lock nut at two points.
12) Installation of differential ASSY.
a. Insert the differential ASSY with-
out axle shaft into final reduction
case.
NOTE:
Pay attention not to damage the axle
shaft oil seal holder bores in final
reduction case.
b. Install the right and left axle shafts
and secure with the snap rings.
Check the clearance between the
differential pinion shaft and the
axle drive shaft to see that it is
within the specifications.

Two snap rings are. available for the
adjustment of the above clearance.

d. Install Handle (899924100) and
Shaft (398653600) to the reduc-
tion drive gear, and turn the gear
several times, and screw in the
holder on the crown gear side until
it lightly bottoms.
Repeat this operation several times
to locate the proper position.
e. Screw in the other holder until it
bottoms.
f. Attach oil seal holder lock plate
and back off holder on the crown
gear side approx. 1.5 notches, and
tighten holder on the opposite side.
g. Temporarily tighten the lock plate
on the crown gear side.
h. Screw in the holder opposite the
crown gear by 0.5 to I notch, and
tighten the lock plate temporarily.
13) Measurement of backlash between
crown gear and drive pinion.
Turn Handle (899924100) several
times, and attach Magnet Base
(49824700 I) with Dial Gauge
(498247100) to Stand.
Check the hypoid gear backlash to see
if it is within the specifications.

14) Crown gear tooth contact pat-
terns.
Apply a coat of Prussian blue over the
three or four tooth faces of the crown
gear, move the gear in forward and
backward directions to obtain gear
contact patterns.
Refer to the figure for various gear
contact patterns.
If proper gear contact patterns are not
obtained, readjust. If correct adjust-
ment has been made, loosen the holder
until the a-ring groove is appeared,
then fit the O-ring into the groove and
tighten in the holder to the position
where the holder has been tightened
to. Place the lock plate on the holder
and tighten it to the specified torque.
Perform the same job with the
opposite axle shaft oil seal holder.

NOTE:
When installing the governor valve,
be careful not to damage the seal ring
and oil seal lip inside of the final
reduction case.
