1. Product Introduction
The transfer box adapted by our company is the transfer box
of 45-55 manufactured by Bogeguana, which is two-speed
and time driving, a set of planetary mechanism used is to
obtain the speed-reducing performance, while the driving
force is transmitted to the front driving gear by a highly precise
chain. The planetary gear train and rear output shaft element
of transfer box is lubricated initiatively through oil bath and oil
pump. This transfer box has four gears:

2H-stands for the two high gears
in which, only the two
rear wheel are driven, and the gear ratio of the transfer box
is 1:1


4H-stands for the four high gears, in which , all of the four
wheel are driven, and the gear ratio of the transfer box is
1:1


N- neutral location (this location only exists in the transfer
box of manual gearshift )
No driving force is transmitted
to the wheel when the input shaft and output shaft are
disconnected.

4L-stands for low gears, the four wheels are all driven, and
the gear ratio of transfer box is 2.48:1.
The gearshift of the mechanical gearshift transfer box is
obtained through the shifting-cam-type guide plate that is
operated by the shift rocker arm.
Sign board: which is fastened at the obvious external location
of transfer box, and on which the detailed data are marked.

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.

(b) Check the front wheel bearing to see whether it is loose.
(c) Check the front suspension to see whether it is loose.
(d) Check the steering driving device to see whether it is
loose, and
(e) Check the front vibration damper work to see whether it
is loose.
