water pump GREAT WALL HOVER 2006 Service Repair Manual

Overview of the entire car-5
The friction, disc, single-diaphragm spring clutch, hydraulic control mechanism. The external diameter of friction disc D=225mm,
internal diameter d=150mm, material is F810.
Adjustment of clutch pedal:
1. Measure the height of clutch pedal (from pedal pad surface to floor) and free stroke of clutch pedal (fork bar pin clearance).
Standard height of clutch pedal: flush with the brake pedal, free stroke of clutch pedal is 5-15mm;
2. Readjust the free stroke of pedal after adjust the height of pedal; rotate the push bar to the standard value, then fix the bolt
and nut;
3. If the free stroke of clutch pedal is not within standard value, it should rotate the adjusting bolt to standard value, then fix
the bolt and nut. Do not move the push bar to main cylinder when adjust the free stroke of pedal;
4. If the free stroke of clutch pedal and clearance between the clutch pedal and floor when the clutch is disengaged de not
consist with the standard, this may by caused by the air in hydraulic system and failure of main cylinder or clutch. It can
discharge the air of system or dissemble and inspect the main cylinder or clutch.

Disassembly /assembly
Cautions for assembly
It should notice the following items before reassemble the transmission system:
1. Ensure the cooler pipeline is washed and all chip is removed when replace the transmission. It can
be realized by using the compressed air to enter into the rear cooler pipeline to remove the oil and
all foreign material in the front cooler.
2. It should check the cooler after the transmission is installed. Ensure the front and rear cooler
pipeline is connected to the proper container. Rotate the vehicle in P-Gear in idle-speed, measure
the flow rate within 15s.
3. The flow within 15s should be more than 1L.
4. It should avoid any water entering into the transmission. This will cause the transmission fluid to
generate the foam or make the transmission fluid flows out form the respirator.
5. Ensure that two grounding wires in vehicle (one end to battery, one end to vehicle) are connected
before the installation of the anode of battery.
6. If the power control module and transmission control unit is exchanged, then calibrate the pro-
gram refer to related throttle position in Part
Removal
1. Transmission
Caution:
It should remove the gear-position sensor before wash the transmission in solvent or hot abluent.
When need to remove the transmission from the vehicle, it should drainage the transmission fluid,
and use the special removal tools.
The removal of the transmission should be processed in module method, the details of removal of each module is described
in following section in detail. Refer to details of special tools listed in table 9.10 and 9.6 when remove it.
The technician needs a set of quality tools when inspect the transmission, especially for dual hexagon spanner of model
30, 40, 50 and 8mm, 10mm, 12mm.
It should abide by the following procedure when disassemble the transmission:
a. Remove the shell of torque converter and torque converter.
b. Place the transmission on the saddle platform.
c. Remove the oil pan and oil pan sealing.
d. Remove the filter retainer of each valve and remove the filter.
e. Remove the wire on solenoid valve, place it in side.
f. Remove the protection screw in the valve and remove the valve from the main housing (remove the model Z connecting bar).
g. Remove the front servo circlip, cover and piston.
Caution:
The plastic servo block on used for piston return spring.
h. Remove the flange shaft fork, then remove the transmission housing (2WD and Chairman).
Use the 8mm hexagon wrench to move the pump to the housing bolt.

CD Player and Air Conditioning System-13
1 .CC6460K air conditioning system is designed with SD7V16 compressor, whose refrigeration oil type as
specified is SP-10P AG; hence application of other type of refrigeration oil may damage the parts and compo
nents of the compressor. When the
air conditioning system goes through maintenance and replacement of
parts, it should be added with new refrigeration oil, whose volume is listed as follows: the evaporator and
condenser: 30ml; the drier: 20ml; the pipeline: 10ml.
Addition of refrigeration oil can be available with two methods: The direct addition and the vacuum suction
2 .D irect addition method
a. remove the oil filler plug and fill with the specified SP-10P AG refrigeration oil.
b. observe through the hole of oil filter plug and rotate front plate of clutch to make the piston connecting rod right positio n in the
center of the hole of oil filter plug.
c. insert the dipstick along the right side of piston connecting rod till the top of dipstick touches the case of the compresso
r
d. pull out the dipstick and examine the graduations (grooves) of refrigeration oil, the readings shall be within the range of 4-6
scales
.
e. screw firmly the oil filter plug with the fastening torque of 14.7± 4.9N
.m
3. Vacuum suction method:
Firstly pump out the refrigerating system to the vacuum of 0.2x105Pa, and then fill with the specified 0.2x10 5 Pa refrigeration oil;
the detailed steps are as follows:
a. switch off the high-pressure manual valve and the auxiliary valve.
b. dismantle the high-pressure side hose from the manifold pressure gauge and insert it into the oil cu
p
c. open the auxiliary valve and have the refrigeration oil sucked into the refrigerating system from the oil cup.
d. when the refrigeration oil in the oil cup is almost pumped out to the vacuum, then immediately turn off the auxiliary valve
to
prevent the air from being sucked into the system
.
e. secure the hose adapter at high-pressure side to the manifold pressure gauge, start the vacuum pump and turn on the high-
pressure manual valve, then turn on the auxiliary valve to pump the system to the vacuum state of 0.2x10
5Pa, keep such state
for 15mins so as to discharge out the air flowing into the system along with the oil.
