Disassembly and Mount of Transfer Box
2. Transfer box mount
a) Coat the lubricant grease on the output axial
spline of the gearbox with a thin sleeve contain-
ing lubricant grease.
b) Mount a new gasket on the mounting face of the
transfer box.
c) Lift the lifting bracket of transfer box and align
it to the same axle with the gearbox.
Notice: The transfer shall be guaranteed to flush
with the gearbox before connecting the spline.
Do not handle it forcefully to press the transfer
box spline into the gearbox. Otherwise, damage
will be caused, run the rear output shaft where
necessary to aim at the spline.
(d) Move the transfer box forward slowly so that
the spline and pin of the input shaft of gearbox
reach the front body of the transfer box, and the
gasket attaches on the gearbox completely.
(e) Ensure that the mounting holes of the front
body of transfer box, gasket, and gearbox are in
alignment and then mount the sets of bolt and
nut.

(f) Connect the rear drive shaft and the rear output
flange of the transfer box.
(g) Connect the front drive shaft and the front
output fork flange of the transfer box.(h) Connect the venting valve and the soft ventila-
tion pipe.
(i) Connect the cables of odometer that locates
nearby the transfer box.
(j) Connect all wire harnesses that connected with
the transfer box, and
(k) Add the lubricant of right brand.
Notice: when starting the engine, if the lubricant
is added incorrectly or in unsuitable volume,
which may lead the transfer box to damage.
Notice: as for the transfer box mounted on
vehicle, oil pump shall be used when adding oil
for it.
Notice: In case the transfer box is taken apart for
maintenance or inspection, there will be no
lubricant supplied by oil pump in the oil passage
on the top of transfer box. Therefore, it is not
accurate to control the oil volume by opening the
oil filling plug, in such condition, the oil passage
will be filled with oil once the oil pump runs. If the
wheel can run, such operation can be conducted
on the lifting jack. The oil level shall be rechecked
once the oil pump runs.
(l) Put down the vehicle after finishing the lubri-
cant inspection, and connect the cell cathode.

7. Deceleration shift parts assembly
The mounting process is as follows:
(a) If the parts are taken apart for change, assemble the shift
toggle fork assembly with a new pin-contact roller
assembly. Press the pin-contact roller in the deceleration
fork hole until the detent passes the hole completely and
seizes the right location. Ensure that the contact roller can
run freely.
(b) Mount two inserted faces of toggle fork on the decelera-
tion toggle fork assembly.
(c) Engage the deceleration fork assembly and deceleration
gear sleeve and put them in the housing, and the decelera-
tion gear sleeve shall be put in the planetary mechanism
assembly that is assembled already. Mount the rear
output shaft and joint the bearings at the ends of output
shaft and input shaft as well as the spline of the gear
sleeve.
Remarks: the output shaft assembly can be delayed until the oil
pump is mounted on the output shaft. The oil pump may be
dipped into the lubricant through the oil pump screen, turn the
output shaft in clockwise from the output shaft direction to see
whether there is lubricant pumped out so as to check whether
the oil pump can work normally or not. The parts mounted
readily may be encased in the transfer box housing as an
assembly
8. Oil pump assembly
Ensure the parts of oil pump are completely lubricated when
assembling, and the oil can be pumped out from the conical
hole of the oil pump front cover. The mount of oil pump is as
follows:
(a) Mount the pin on the rear output shaft.
(b) Slide the oil pump assembly on the rear output shaft
along with the pin.
(c) Put the gripping hoop at the end of oil pipe that is
mounted on the oil nozzle of the pump housing, screw up
the gripping hoop.

(d) All of the following aligning conditions shall be satisfied
when the rear cover assembly is mounted on the transfer
box front housing:
a) Align the pin hole in the rear cover to the pin on the
housing.
b) Align the rear output shaft to the inner bearing in
cover rear hole.
c) Align the blind hole in the rear cover and the shift
guide shaft; ensure the return spring is not tilted.
Check the hole in velocity sensor of the rear cover
with a pen.
d) Align the shift shaft and the inner bearing in rear
cover.
(e) Screw up the nine bolts after locating the sign bolts
correctly.
(f) Encase the gear of odometer in the rear cover assembly
through the spline of the rear output shaft.

transfer box.
(b) Mount the magnet in the groove of the housing.
(c) Coat the Letai glue 598 of 1.6mm on the coupling face of
housing, steer clear of the screwed hole when coating
continuously.
Notice: try to button the rear cover on the transfer box front
housing with the moderate force during the following process.
Not too much force is required when mounting the rear cover
on the front housing when all aligning conditions are satisfied,
in case the rear cover cannot be mounted on the front housing,
take down the rear cover assembly to check the aligning

Washing, Checking, Up-Keeping and Exchanging (Washing)
1. Washing
Notice: check the metal rag around the magnet first before washing, large granule or irregular metal
granule shows the disintegratation or similar damage. Small or fine metal granule shows the uneven
or serious wear. If the metal rag is founded, notice shall be taken on damage and wear inspection
during checking the rotating parts and the element matched with the rotating parts.
(a) Common washing
Wash the parts in cleaning agent to clean away the old lubricant and deposit. Clean away the deposit in oil hole
with brush. Take notice not to scrape the metal coupling face when washing the parts cannot be cleaned with
brush.
(b) Dry the washed parts by blowing
Dry the washed parts by blowing the low-pressure compressed air (max pressure is 137.9kPa), because cloth
thread may be left during cleaning the parts with cloth. The bearing shall be held by hand to prevent it from
rotating when blowing it.
(c) Bearing lubrication
The ball bearing and needle bearing shall be lubricated with the lubricant for transfer box after washing. As
the non-lubricated bearing may cause damage when be dry. Cover the lubricated bearing to prevent dust
entering in.

Checking
1. Common Checking process
Check all parts by visual check to see whether there is damage
or serious or uneven wear (parts needed be substituted by new
parts such as O-ring, oil seal and etc. shall be excluded).
Abandon the damaged or weary parts that will affect on their
performance. The check items are as follows:

Burr: tips protruded from the material regionally

Rag: broken small blocks or particles

Crack: surface thread showing the material is partly or
completely separated.

Excessive abrasion
Refer to the serious or obvious abra-
sion beyond of application limit.

Reduction change
Material slip caused by the heavy
pressure on part of it.

adhesive bonding
Granules of the soft metal are dis-
persed and bonded on the hard metal surface.

Ditch trance: partial crack or trough that means the material
transfer instead of material loss.

Pitting corrosion
Damages to the metal surface caused by
pressure, which are displayed due to color change caused
by heat generated by metal friction.

Step wear
a weary step may be seen or felled between the
neighboring interface or between the non-touching face
due to the excessive wear.

Uneven wear: Partially, unevenly distributed wear, which
includes holes, bright spots, uneven polishing or other
visual drawbacks.
2. Gear or Chain sprocket tooth inspection
Check the gear and chain sprocket tooth according to the
following process:
(a) Normal gear shaving trace.
