11. Check the engagement situation of the axle driven bevel
gear and the driving bevel gear:
(a)
Coat four teeth locating on different spots of axle driven
bevel gear with red powder.
(b)
Rotate the axle driven bevel gear in different directions.
(c)
Check the teeth engagement situation.
The teeth trace of axle driven bevel gear should satisfy
this requirement. If not, select the suitable adjusting
washer to correct according to the poor teeth engagement
situation.

12. Lock the double-eared stop washer to mount the stop
gasket and bolts:
(a)
If the engagement trace satisfies the requirement, lock
tightly the double-eared stop washer with hand hammer
and pinch.
(b)
Mount on the stop gasket, spring gasket and bolts, and
then screw up the bolts.
Tightening moment
(18-26)Nm
(c)
Tap in he adjusting ring with the pinch and hammer.
13. Measure the total preload:
Preload: (1.8-2.4) N
m
If the preload is beyond the specified range, change the gas-
kets between the jacket and bearing 7607E, until they meet
the requirement.
(a)
If the preload is larger than the specified value, change
the adjusting washer.
(b)
If the preload is smaller than the specified value, screw up
the nuts again slowly but not exceed 160N.m.
Notice: if the screwing torque exceeds the max torque,
change the adjusting washer and repeat the preload
process. Do not screw back the main-tooth nut to reduce
the preload.
14. Check and adjust the flange bouncing
(a)
Attach the dial indicating lamp seat on the speed reducer
housing with the measuring head contact the flange face,
run the flange to observe the swing out range of the dial
indicating lamp hand.
Radial full bouncing tolerance
0.10mm
Remark: the two bouncing values should be controlled within
0.10 mm, as for the parts of bounce exceeding the tolerance,
loosen the nut-driving bevel gear to assembly them in another
angle, measure the bounce value again. Observe carefully the
swing direction of the hands, which can be referred when
changing the locations of flange and the driving bevel gear. If
the requirement cannot be satisfied after several trials, change
the new flanges until the requirement is met.

Mount of Rear Speed Reducer and
Differential Assembly
1.
Mount the speed reducer and differential assembly on
the rear axle housing.
Tightening moment
(18-26)Nm
Remark: in case the sealing gasket is mounted, it should be
checked to see whether it is damaged before mounting, if
damaged, change with the new sealing gasket, and the dam-
aged sealing gasket should be clear away; if no sealing gasket
is mounted, no mount is required to mount. Clean the contact
face of the mounted axle housing and coat it with silicon-
rubber plain sealing agent.
2.
Connect the drive shaft and flange well and be careful to
align the assembly marks marked when disassembling.
Tightening moment
(69-79)Nm
Screw up the oil drain plug with the Tightening moment
of (140-150)N
m
Mount on the half-shaft and the brake assembly to adjust the
brake oil path so that the wheel brake pump is filled with brake
liquid.
3.
Inject in the heavy-duty oil.
Oil brand: heavy-duty oil graded GL-5;
Viscosity: SAE 85W/90
Oil volume: add the oil until it overflows from the oil filler
outlets.
Screw up the oil-filling plug.
Tightening moment
(140-150)Nm
