value of the swing difference is excessive, change the half-
shaft.
2. Check he oil seal of rear wheel bearing:
Check to see whether there is wear or damage, and change the

7. Check the bearing seat.
Check the wear or damage situation.
8. Change the bearing seat where necessary:
(a) Tear down the oil seal of rear wheel bearing and the
grooved ball bearing with SST.
(b) Tap the bolts with copper bar to tear down the bearing seat.
(c) Mount the new grooved ball bearing and the oil seal of
rear wheel bearing on the bearing seat
(d) Press the rear brake, which is put on with bolts, in the
bearing seat.
9. Check the wear or damage of the inner oil seal of the rear
wheel bearing.
10. Change the rear wheel bearing where necessary:
(a) Tear down the oil seal of rear wheel bearing with SST. Suspension System and Automobile Axle (rear)
Rear half Axle Shaft

SA-82
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.

Notice: protect the oil seal lip open, bracing wire assembly
and the oil-guard sleeve.
5. Mount on the hand brake wire and the brake pipe.
6. Mount on the liner and rear brake drum;
7. Make a trial gas exhaust on the braking system, and
8. Mount on the rear wheels.

On-vehicle Change of main-teeth oil seal
1. Disconnect the drive shaft from the speed reducer:
(a) Mark the assembly mark on the two flanges;
(b) Tear down the four sets of bolt and nut.
2. Tear down the flange and dust cover assembly.
3. Tear down the oil seal.
Tear down the oil seal with SST.



4. Mount on the new oil seal:
(a) Coat the lithium base grease on the lips of oil seal;
(b) Tap in the new oil seal with SST.
Remark: tap the new oil seal until it is in place.
5. Mount the flange and dust cover assembly.
6. Screw up the nut to the specified torque.
Specified torque: (140-160)N
m
7. Rivet the nut.
8. Connect the drive shaft flange with the speed reducer
flange:
Align the assembly mark and connect the flanges with bolts.

9. Check the oil level of the speed reducer.
Change the gear oil where necessary.
Oil brand: heavy-duty oil of grade
GL-5
Oil volume: add the oil until it overflows from the oil filler
outlet.

Rear Speed Reducer

SA-85
Dismantle of Rear Speed Reducer
1. Take out the oil drain plug to drain the oil in the speed
reducer up.
2. Tear down the rear axle shaft.
3. Disconnect the drive shaft from the speed reducer.
4. Tear down the nuts on the bolts that connect the rear axle
housing and the speed reducer.
5. Tear down the rear speed reducer.
Disassembly of Rear Speed Reducer
Remark: in case the noise is over loud, the following item
should be checked before taking apart it to find out the causes.
If the speed reducer has serious drawback, take it apart for
repairing where necessary.
1. Check the play between the axle driven bevel gear;
In case the play value fails to be within the specified range,
adjust the preload of bearing 200719E or repair it where
necessary.
(see page SA-91)
Standard play: (0.13-0.25)mm
2. Check the teeth engagement of the driving bevel gear
with the axle driven bevel gear.
(See Page SA-92)
Record the teeth engagement positions.
3. Check the clearance between the half-shaft gear thrust
gasket and the differential housing.
Check the clearance between the half-shaft gear thrust gasket
and the differential housing with the feeler.
Standard clearance
(0.45-0.75)mm
Remark: in case the clearance value fails to fall within the
above range, change the half-shaft gear stop gasket, and
ensure the half-shaft gear stop gaskets on the left and right
sides are same in thickness.
