b) The raised vehicle must be supported with the bracket; it is
dangerous to conduct the repairing work on the vehicle propped
up with one jack, even though such repairing can be finished in
short time.
12. The following items shall be taken notice to avoid the parts damage:
a) Do not open the covers of ECU and various computers where not
necessary absolutely. (if the IC terminal is touched, it be leaded
into static damage) .
b) Pull the hose at its ends when dismantling it, do not pull it at the
center section.
c) Pull the wire joint instead of the wire when pulling the joint
away.
d) Take notice to avoid of the drop of electric parts such as the
sensors or repeaters. In case those parts drop to the hard ground,
they must be changed instead of being reused.
e) Do not use the striking spanner to dismantle or mount the
thermostatic switch or thermostatic sensor.
f) Plug the needles of the multi-meter into the wire connector
carefully when checking its conductance and do not bend the
terminals.
g) Do not sheath the hose of the vacuum gauge into the very large
connector when using the gauge, instead, the stage joint shall be
used because once the hose expands, it is possible to lead into
the leakage.

when exchanging the engine lubricant or after the vehicle
covers 8000 kilometers, and the lubricant shall be added
as requirement.
(b) The lubricant shall be changed with the specified one
every year or after the vehicle covers 48000 kilometers.
3. Lubricant inspection approach
(a) Clean the oil filling plug and the around area.
(b) Open the oil-filling plug to check whether the lubricant
can flows out or not.
(c) if the lubricant can flow out, which means the real

Notice: The vehicle shall run for a certain time before
checking or exchanging the lubricant so that the
temperature of lubricant in transfer box may be a little
higher. Do not use hammer or other punching tools to
open or propel the oil drain plug or oil filling plug, otherwise,
the thread hole on the frame will be damaged
4. Lubricant change
(a) Clean the oil filling plug and oil drain plug and the around
area.
(b) Put down a oil container under the transfer box.
(c) Open the oil drain plug.
(d) Open the oil-filling plug.
(e) Drain the lubricant up.

Transfer box assembly
1. Introduction
Please refer to the given instruction of this chapter during
assembly process. And the following items shall be taken
notice on:
(a) In case that the torque of the threaded parts is required,
torque spanner shall be used to screw up the parts.
(b) The small parts shall be coated with the lubricant grease
during the mounting process, so that they are immobilized
at the mounting locations.
(c) SST such as thimble of T-13-54-001 shall be used to press
the oil seal and bearing during the oil seal mount and
bearing mount, do not use the hammer to strike the oil seal
or bearing directly.
2. Lubricating during assembling
All inner parts without lubricant shall be lubricated with the
suitable lubricant before mounting, so that they can be as-
sembled easily and can supply the original lubricant
performance.
(a) If the O-ring and oil seal were not lubricated before
mounting, they may be damaged.
(b) Be sure that the bearing or liner is lubricated completely
before mounting. Because the bearing or liner may be
leaded into damage even though they are run for a very
short time.
(c) The lips of oil seal and the metal elements that match with
lips shall be lubricated before mounting.
3. Transfer box housing assembly
Parts taken apart from the transfer box shall be mounted
according to the following approaches:
(a) If the gear ring needs to be changed, the tooth-type saddle
rear of new gear ring shall be flushed with the gullet of the
transfer box front housing when pressing the new gear
ring. Press in the gear ring as shown in the left bottom
drawing, in which, the chamfering end is firstly pressed
in. if it is ensured the gear ring is not tilted, then fasten the
gear ring tightly on the housing.
(b) In case there are two locating pins taken apart, mount two
new locating pins into the housing.
(c) Press the bearing into the transfer box front housing and
mount the snapping ring correctly, and
(d) Put down the new oil seal as shown in the left bottom
drawing and press it into the housing.

3. Take apart the universal joint yoke from the rear joint of
rear axle drive shaft.
(a) Label the universal joint yoke and the shaft with assem-
bly marks.
(b) Pull out the universal joint yoke from the shaft.
Inspection on Drive Shaft Parts
1. Cross shaft bearing inspection
Check the wear or damage situation of the cross shaft bearing
and change the weary or damaged bearing where necessary.
2. Check the wear and damage situation of the central
bearing.
Check the bearing to see whether it can run freely.
In case that the bearing is damaged or wearied or cannot run
freely, change it in time.

6. Inspection and replacement for front brake disc
(a) Check the wear situation of the front brake disc. (see Dr
the brake caliper).
(b) Use the spanner to tear down the bolts that connect the
front wheel hub and the front brake disc.
(c) Connect the front wheel hub and the front brake disc with
bolt and spring washer, and screw up the bolts with a
moment spanner to the specified torque in the diagonal
order.

(d) Conduct the equilibrium test on the dynamic balancer,
the amplitude value displayed should not be larger than
13.5g under the condition that the measuring rotating
velocity is 796 r/m and the locking rotating velocity is
786 r/m, when the amplitude value is larger than 13.5 g,
encase the counter balanced clip, which is 4 g each, at the
corresponding phase, the number of the clip encased
should not be more than four.
7. Bearing outer race change
Press in the new bearing outer space with the special service
tools.
Notice: the bearing inner and outer races should be changed at
one time.
Assembly of Front Wheel Hub
1. Mount on the Bearing 32007 inner race and roller assem-
bly as well as the front wheel hub oil seal.
Coat the lithium base grease of (4-5)mm on the inner surfaces
of bearing outer race and the front wheel hub, encase the
Bearing 32007 inner race and roller assembly, plaster the
lubricant again. Coat a little lubricant on the lips of front wheel
hub oil seal and then tap it in place.
Notice: do not make the lubricant contact the front brake
disc face.
2. Mount on the Bearing 32007 inner race.
After coating the bearing outer race with the lithium base
grease of 4-5 mm, encase the inner race and roller assembly of
Bearing 30205, and plaster the lubricant again.

5. Tear down the front hub, the oil seal and the inner race
of front hub bearing (inner)
(a) Prize out the oil seal.
(b) Take out the inner race of front hub bearing (inner).
6. Inspection on and change of the outer race of front hub
bearing
(a) Check each bearing:
Wash the inner and outer races of each bearing to check
their wear or damage situation.
(b) Tear down the outer race of each bearing:
Tap out the outer bearing race with copper bar and hammer.
Notice: bind the inner and outer races of the same
bearing together to prevent from mixing.
7. Inspection and change for front brake disc
(a) Check the wear situation of the front brake disc.
(b) Tear down the bolts that connect the front wheel hub and
the front brake disc.
(c) Connect the front wheel hub and the front brake disc with
bolts, which are tightened diagonally with moment span-
ner according to the specified torque.

(d) Make the dynamic balance test on the dynamic balancer,
and the amplitude value displayed should not be smaller
than 13.5g under the condition that the measuring rotat-
ing velocity is 796 r/m and the locking rotating velocity
of 786 r/m, otherwise, tap the counter balanced clip,
which is 4g each, in the corresponding position, the clip
number should not be more than 4.
(e) Tap in the new bearing outer race carefully with the
special service tool.
Notice: the inner and outer races of the same bearing
should be changed in one time.
