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) In the case that the input shaft is taken apart, what need
to do is to fill the needle bearing as shown in the drawing
and press it in the input shaft, meanwhile, press the new
sliding bearing to complete the whole input shaft assembly.
(f) Raise the planetary mechanism assembly to mount it into
the input shaft assembly; encase the thrust gasket and
press in the bearing through the input shaft end. Encase
the fixed bearing in the snapping ring groove of the input
shaft with a snapping ring.
(g) If the transfer box front body is taken apart, press the new
located pin in the front body, and the pressing dimensions
are shown in the drawing.
(h) Put down the oil seal as the drawing shows, and press it
in the front body according to the dimensions shown in
the drawing.
(i) Put down the front body assembly on two wooden blocks
in the way that the coupling face of the front body and the
housing faces upward, so that there is clearance left
between the input shaft assembly and the worktable. Put
down the input shaft and planetary mechanism assembly
in the front body, in which the input shaft shall be
downward. Open the long ends of the snapping ring to
encase input shaft and planetary mechanism assembly
until the snapping ring enters into the external snapping
ring groove of the bearing.
(j) Coat the sealing glue of 1.6mm on the coupling locations
of the front end cover and transfer box assembly, The
glue shall be coated continuously without break and steer
clear of the screwed hole.
(k) Screw up the six bolts.

coupling face of the rear cover shall face upward and
parallel with the work face of the press machine.
(b) Locate the needle bearing, of which the marked end
facing upward, and press it in the rear cover until the
upper end of needle bearing is 40.47
40.97 lower than
the coupling face of the rear cover that matches with the
front housing.
(c) Press the ball bearing in the rear cover and mount the
snapping ring well.
(d) As for the electric shift transfer box, the parts shall be
encased according to the following process:
(1) Confirm the four O-rings are set on the clutch
washer assembly (one O-ring is located on the coil,
the other three on studs).
Mount on the clutch coil assembly, of which the
wire and stud shall protrude out the rear cover, take
notice not to damage the wire when screwing up the
