IN-4
Overall Repairing Description
1. Keep the vehicle clean and prevent it from
damage with guard plate, seat and floor cover
cloth.
2. Put down the dismantled parts in order during
the dismantle process so as to facilitate the re-
assembly
3. Observe the following items:
a) Disconnect the cable cathode from the
accumulator terminal before the electric
operation;.
b) Disconnect the cable from the cathode
connected to the vehicle body when check-
ing or repairing the accumulator where
necessary.
c) In order to avoid the damage of terminal
post of accumulator, loose the bolts first,
then pull up the cable vertically when
dismantling, don
t wring it or prize it.
d) Clean the terminal posts of the accumula-
tor with dishcloth, and do not scrape them
with file or other similar tools to avoid
damage.e) Mount the cable terminal on the post with loosened nut, then
fasten the nut. donít tap the terminal onto the post with
hammer.
f) Be sure to check whether the cover of positive terminal (+) is
well located or not.
4. Check all hoses and wire plugs to verify whether they are
connected solidly and correctly.
5. Parts that cannot be reused after being used.
a) The following parts should be changed with new one regularly:
split pin, sealing washer, O-ring and oil seal, etc.
b) parts that cannot be reused after being used is marked with

 in the element figure.
6. Pre-coated parts
The pre-coated parts including the bolt and nut are coated with
locking seal glue in factory.
a) In case the pre-coated parts are moved due to its fastening,
loosening or other causes, they must be coated again with the
specified seal glue.
b) Coating procedure of pre-coated parts
1) Clear away the former seal glue from the screw thread of
the said parts.
2) Dry the parts with compressed air.
3) Coat the screw thread of the parts with the specified
locking seal glue.
c) The pre-coated parts are marked with the
 in element
figure.
7. When necessary, sealing agent or sealing ring to prevent the
leakage.
8. Each specification shall be followed strictly. And the torque
spanners should be used.
9. Determine the necessity of using the special service tools (SST)
or special service materials (SSM) according to the real situation.
SST and SSM must be used where necessary and the repairing
should be in accordance with the repairing approach. SST list
and SSM list are attached to this manual.
10. Be sure to check whether the rated current of the new fuse is
correct when changing the fuse. The fuse rated current should
not larger than that of securing fitting and the fuse of smaller
rated current must not be used.
11. Be careful to hang or support the vehicle on the suitable place
when propping up or raising it.
a) In case prop up the vehicle at the front or back part, the wheels
must be blocked to guarantee the safety work. Introduction

Inspection and Adjustment of Clutch Pedal, Air Exhausting of Clutch
Air-exhausting of clutch
Remark: in case operation needs to be conducted for the clutch
system or if there is air in clutch, exhaust the air.
Notice : Do not stain the painted surface with brake liquid,
if any brake liquid is left, wash it away immediately.
1.
Fill the brake liquid into the oil cup of clutch master cylinder;
The oil cup of master cylinder shall often be checked and, if
necessary, added with brake liquid.
2.
Connect the ethene resin pipe to the air-exhausting valve.
Insert the other end of the pipe into the container, half of which
is filled with brake liquid.
3. Air-exhausting in clutch system
a) Move the clutch pedal up and down slowly for several times.
b) Loosen the air-exhausting valve when pressing the pedal
increasingly until there is brake liquid overflowing, then
tighten the air-exhausting valve.
c)
Repeat this operation until the bubble in brake liquid disappears.
Inspection on and adjustment
of clutch pedal
1. Check whether the pedal height is correct
Pedal height that begins from front wall board:
Dr SF
(165
5)mm
SL SK SY SJ
(190-200)mm
2. Adjust the pedal height where necessary
Loosen the locking nut and screw off the adjusting bolts until
the pedal height is correct. Then screw up the locking nut.
Pedal free stroke
3. Check whether the pedal free stroke is correct
Press the pedal lightly until the resistance generated by clutch
occurs.
pedal free stroke: (5-15)mm
4. Adjust the pedal free stroke where necessary;
a) Loosen the locking nut and rotate the push-rod until the
stroke is correct;
b) Screw up the locking nuts;
c) Check the pedal height after the adjustment of pedal free
stroke.

TF-65D5D-Oil filling plug
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.
