Disassembly and Mount of Transfer Box
Disassembly and Mount of Transfer Box
1. Transfer Box Disassembly
(a) Drive the vehicle on the lifting jack.
(b) Locate the gear of transfer box at the neutral
position, shift the transfer box to the 2H and
extinguish the engine.
(c) Disconnect the cell cathode.
(d) Lift the vehicle.
(e) Put down an oil disc under the transfer box, tear
down the oil drain plug and oil filling plug of the
transfer to drain all the lubricant up, then re-
mount the two plugs.
(f) Disconnect all wires and wire harnesses that
connected with the transfer box.
(g) Take apart the hose on the venting valve of
transfer shaft.
(h) Disconnect the linkage of the front drive shaft
with the front flange of the transfer box.
(i) Disconnect the linkage of the rear drive shaft
with the rear flange of the transfer box.
(j) Raise the transfer box up with the jack.Notice: The transfer box shall be guaranteed to
support by the lifting jack before tearing down
the sets of bolt and nut that connected with the
transfer box and gearbox. The transfer box is
not allowed to hang directly on the gearbox
through spline because such operation will
damage the transfer box parts.
(l) Tear down the connecting nuts between the
transfer box and gearbox and take down the
transfer box.
(m) Move the transfer box backward directly until
the linkage between the input shaft of transfer
box and the gearbox spline.
(n) Put down the lifting jack of the transfer box, and
(o) Tear down the gasket between the transfer box
and gearbox. Clean the gasket or glue on the
coupling face of front body of transfer box with
rear body of the gearbox. Take notice not to
damage the coupling face.

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.

Three-grade maintenance for gearbox
1. Grade I maintenance for gear box
Grade I maintenance: Check the lubricant level to see whether the lubricant level is in alignment with the lower edge of oil
filler; if the lubricant is lower than the oil filler lower edge, add the lubricant; or the insufficient lubricant will lead to the poor
lubrication or burn-out of bearing and teeth; while the over-high lubricant will cause the overheating and oil leakage.
2. Grade II maintenance for gear box
Grade II maintenance: The gear box of a new vehicle should be maintained by exchanging the lubricant during the
first grade II maintenance and should be washed with kerosene; and the lubricant quality should be checked in the
grade II maintenance in later time, if the lubricant is diluted, gumming or over-dirty, it should be changed.
3. Grade III maintenance
The gearbox should be disassembled for inspection, washing and oil change.
Notice: As the new vehicle is in the running-in status, the gearbox should be maintained by exchanging lubricant
after the vehicle covers 1500 km,
