11. Mount the new inner oil seal of rear wheel bearing.
Coat the hyperbolic gear oil on the axle housing where matches
with the oil seal; and plaster the moderate lithium base grease
on the lip open of the oil seal, then put them on the pressure
head and press them in.
Mount of Rear Axle Shaft
1. Press the rear brake and the bearing seat assembly on
the haft shaft.
2. Press the heated inner oil seal seat of rear wheel bearing
on he half shaft;
Notice: the face at the chamfering end of inner oil seal of
rear bearing should contact the oil seal closely, do not
mount it at the incorrect position.
Requirement for heat mount: heat the inner oil seal seat into the
22# oil (GB443-1989) to 100
, after the part is heated
completely, take it out for mount.
3. Mount on the flat steel retaining ring with the ring calipers.
4. Encase the half-shaft rear brake in the axle housing,
screw on the self-locking nut.

9. Mount on the differential bearing cover:
(a) Align the assembly marks on differential bearing cover
and the speed reducer housing, and press down the
differential bearing by hand.
(b) Mount on the double-eared stop washer and the hex nut.
10. Adjust the clearance between the driving bevel gear and
the axle driven bevel gear
(a) Screw up the hex nuts connecting the differential bearing
cover to the specified torque.

(b) Attach the measuring meter seat on the face of speed
reducer housing with the measuring head touching the
teeth face, run the axle driven bevel gear with hand to
measure the teeth engagement clearance, and then com-
pare it with the clearance value in step (d) to decide the
order of the adjusting ring tightening according to the
values.
(c) Adjust and screw up the adjusting rings with SST.
Tightening moment
(115-135)N

(d) Check the engagement clearance again until the clear-
ance value of the three spots evenly locates on the
circumference of axle driven bevel gear. Otherwise,
adjusting ring adjustment is suggested.

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)N

(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. Suspension System and Automobile Axle (Rear)
