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.

5L-Oil drain plug5L2. Regular lubricant change
(a) The oil level of lubricant in transfer box shall be checked
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
lubricant volume is under the prescribed value, and the
specified lubricant shall be added into the transfer box
until the lubricant can flow from the oil filler hole.
(d) Propel the oil-filling plug tightly according to the given
Tightening moment.

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.
(f) Mount the oil drain plug and screw it up according to the
given Tightening moment.
