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.
