b) The raised vehicle must be supported with the bracket; it is
dangerous to conduct the repairing work on the vehicle propped
up with one jack, even though such repairing can be finished in
short time.
12. The following items shall be taken notice to avoid the parts damage:
a) Do not open the covers of ECU and various computers where not
necessary absolutely. (if the IC terminal is touched, it be leaded
into static damage) .
b) Pull the hose at its ends when dismantling it, do not pull it at the
center section.
c) Pull the wire joint instead of the wire when pulling the joint
away.
d) Take notice to avoid of the drop of electric parts such as the
sensors or repeaters. In case those parts drop to the hard ground,
they must be changed instead of being reused.
e) Do not use the striking spanner to dismantle or mount the
thermostatic switch or thermostatic sensor.
f) Plug the needles of the multi-meter into the wire connector
carefully when checking its conductance and do not bend the
terminals.
g) Do not sheath the hose of the vacuum gauge into the very large
connector when using the gauge, instead, the stage joint shall be
used because once the hose expands, it is possible to lead into
the leakage.

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.

b) Align the rear output shaft to the inner bearing in
cover rear hole.
c) Align the blind hole in the rear cover and the shift
guide shaft; ensure the return spring is not tilted.
