TF-8Transfer Box
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.

Disassembly of Transfer Box
1. Brief instruction
In case the transfer box is required to be repaired for the
damaged specific element, it shall be taken apart to the degree
on which the damaged element is taken out. And the parts
taken apart from the transfer box, if it doesnít include the
damage element, can exist in the form of sub-assembly or
group instead the individual form, otherwise, the parts will be
taken apart individually.
2. Transfer Box Disassembly
Put the transfer box on the worktable and ensure the rear part
or the rear cover faces upward. Put the wooden block under the
front part of transfer box to keep the transfer box stands
horizontally. The disassembly process is as follows:
(a) Fasten the flange with the torque arm typed T-13-54-
002, screw off the nut to take down the gasket, then take
apart the flange and oil seal.
(b) Take down the two oil plugs from the transfer box body.
As for the electric gearshift transfer box, tear down the
electric shifting element according to the following
disassembly approach:
(a) Tear down the three bolts, gaskets, sensor and clip for
wire harness.
(b) Tear down the sensor assembly and take apart the O-
ring.
(c) Tear down the motor 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.

(e) Mount the electric shifting cam on the shift shaft in such
way that the free end of the driving tongue of the cam is
put in first, fasten the cam driving tongue, which shall be
between the two spring ring of two torsion spring, under
the driving tongue of shift shaft and put it innermost as
can as possible.
(f) After mounting the toggle fork, then mount the electric
shifting cam assembly in the transfer box housing assembly
5. Assemble for front body, input shaft assembly and plan-
etary component element.
Mount the following element on the worktable:
(a) Put the planetary bracket assembly on worktable, and the
end with snapping ring groove shall face upward.
(b) Mount in the sun wheel and let the part with projecting
end upward, run the gear of the planetary bracket assem-
bly until it completely engages with the sun wheel.
(c) Flush the projecting teeth, and then mount the thrust disc
into the planetary bracket assembly.
(d) Mount in the snapping ring to complete the whole plan-
etary bracket assembly.

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.
