12. Measure the clearance between the axle driven bevel
gear and the driving bevel gear with dial indicating lamp.
Clearance: 0.15-0.25mm
Remark: if the play fails to fall within the specified range,
change with the adjusting gasket of other thickness to satisfy
the requirement under the precondition there is no clearance
between the adjusting gasket and the differential.
14. Measure the total preload of the front speed reducer with
torque tester;
Fastening torque
(1.8-2.4)Nm
13. Mount on the left and the right cap-differential bearing:
Screw up the bolts with spanner to the specified torque;
Fastening torque
78Nm
15. Check the teeth engagement between the axle driven
bevel gears:
(a)
Coat three or four teeth at three different positions of the
axle driven bevel gear in red
(b)
Hold the flange tightly while rotating the axle driven
bevel gear.
(c)
Check the teeth engagement situation.
Remark: the trace of the teeth of axle driven bevel gear should
satisfy this requirement. Otherwise, select the suitable adjust-
ing washer for correcting according to the situation of poor
teeth engagement;
Select the adjusting gasket that makes the main teeth apart
from the axle driven bevel gear.

half-shaft.
(a)
Mount the new snapping ring on half-shaft.
(b)
Mont on the front semi-axis and the front minor half-
shaft.
20. Mount the front speed reducer shell assembly:
(a)
Clear the front speed reducer shell and the contact face of
front speed reducer shell;
(b)
Coat the glue line with diameter of 2-3 mm, and the glue
line should be even and without fracture.
Remark: The front speed reducer shell should be mounted
ready within 15 min after coating the glue.
(c)
The bolts, before screwed up, should be coated with
thread locking sealing agent and screwed up to the
specified torque.
Fastening torque
47Nm
