TableEngine AssemblyEngine Inspection3-2 Note:
Check the belt distortion at the specified point (see Figure 1-1).
When mounting a new belt, set the tensioning force to specified value.
After the belt has been operated more than 5 minutes, check and ensure the distortion not exceeding specified
value. (2) Make sure that the coolant level is above the neck of the radiator.
(3) Put the radiator cover in place, pressurize to 2.0Mpa, and keep the pressure for 1minute unless the coolant
leaks. (Mount a tester on the radiator cover, start the engine, and then shut down under a pressure 2.0Mpa).
(4) Check whether the coolant quantity in the dilatation can is between the mark "Low" and "Full".
(5) Check whether the radiator cover is clean; test whether the opening pressure of the main valve is 107.8KPa
with a radiator cover tester. The minimum opening pressure is 58.5KPa.
6. Check the battery.
(1) The terminal voltage of the battery is 12.5-12.9V at 20°C, and charge when the voltage value is less than
the specified value. Check whether the fusible cutout and the fuse are loose, corrosive or on.
7. Check the air filter.
(1) Whether the cover, the case or the element of the filter is distorted, corroded or damaged.
(2) Whether the air hose is damaged.
(3) Whether the air chamber is distorted or damaged.
(4) Whether the air filter element is blocked, polluted or damaged. If the filter element is blocked slightly,
remove the dirt by blowing the element from above.
(5) Whether there is any pollutant or dirt on the air filter support.
8. Check the spark plug.
(1) Spark generation.
a. Disconnect the coupling of the injector.
b. Remove the spark plug from the secondary wire.
c. Remove the spark plug.
d. Connect the spark plug to the secondary wire.
e. Ground the spark plug.
f. Start the engine, and check whether spark is generated.
Prompt: The starting time is not more than 1-2s.
(2) Clean the spark plug: The air pressure is not greater than 588kp and the time is not more than 20s.
(3) Check whether the thread and the insulator of the spark plug are damaged. Replace if necessary.
(4) Check the electrode gap of the spark plug: 0.8±0.1mm for MR479Q and MR479QA; 1±0.05mm for
MR481QA.
9. Check the driving belt.

Figure 1-2
Figure 1-3Engine AssemblyEngine Inspection3-3 After the belt is re-mounted and operates more than 5 minutes, check the distortion based on old belt
distortion.
Check the tensioning force and the distortion of the V-belt after the crankshaft of the engine has rotated 2
turns.
10. Check the ignition timing (see Figure 1-2).
(1) Start the engine for warming up.
(2) When using the portable tester:
Connect the portable tester to the fault diagnosis socket
(DLC3).
Ignition timing:
before the top dead center when idling.
Prompt:
Please refer to the operating manual of the portable tester for
detail.
(3) When not using the portable tester:
a.Short the terminals 13(TC) and 4(CG) of the fault diagnosis socket(DLC3) with special service tool(SST).
Attention:
Make sure to connect correctly, or else the engine can be damaged.
Switch off all the electric systems.
Check when the cooling fan motor is disconnected.
b.Check the ignition timing with a timing light.
Ignition timing: 10°±20' before the top dead center when idling.
Note:
(a) Check the ignition timing, and the transmission should be set to the neutral position.
(b) Keep the engine speed at 1,000-1,300r/min for 5s and check when idling.
(c) Remove the special tool on the fault diagnosis socket.
(d) When the engine speed rises, the advance angle of ignition timing will increase.
(e) Remove the timing light.
11. Check the engine idle (see Figure 1-3).
(1) The engine warms up.
(2) When using the portable tester: Connect the portable tester to the fault diagnosis socket (DLC3).
Tip: Please refer to the operating manual of the portable tester for
detail.
(3) When not using the portable tester:
Connect the test pen of the tachometer to the terminal 9(TAC) of
the fault diagnosis socket (DLC3) with special tool (SST). (see
Figure 1-3).
(4) Check the idling speed: 800±50r/min.
Attention:
Check idle when the cooling fan motor is disconnected.
Switch off all the electric accessories and air conditioners.Tachometer

Section 3 Drive Belt Replacement1. Remove the V-belt of the generator (see Figure 1-9).
(1) Release bolts A and B.
(2) Release the bolt C and remove the V-belt.
2. Remove the V-belt (from the air conditioner compressor to the
crankshaft sheave (see Figure 1-10).
(1) Release the nut A.
(2) Release the bolt B, and remove the V-belt.
3. Remove the belt of the water pump.
Release bolts A and B, and remove V-belt.
4. Mount the V-belt of the water pump.
Mount the V-belt on the sheave briefly.
5. Adjust the V-belt of the steering pump (see Figure 1-11).
(1) Adjust the tension of the power steering belt, and fasten the
bolt B.
(2) Fasten the bolt A.
Torque: 39N.mFigure 1-9

Figure 7-3Automatic Transaxle Assembly Hydraulic Torque Converter and Transaxle3-31Figure 7-5 Figure 7-4Figure 7-1
Figure 7-23. Install transmission in the engine, its way like manual transmission. The torque converter cannot be allowed to
move in axial motion during operating (The dimension of A keeps constant). Install starter in the transmission
housing.
4. Connect Flexibility plate with torque converter, using 3 special bolts. The way is as follows. First, assemble one
bolt in the torque converter by the longer hole of the Flexibility plate, and then rotate engine belt pulley to install
the other bolts, finally use torque spanner to tighten the bolts. Tightening torque is 40~50N.m.
5. Install suspension bolt and drive shaft LH&RH, the assembling way like manual transmission.
6. Connect two cooling pipes as showed in the figure 7-3 with the corresponding pipe of transmission with clip.
7. Connect the cable between bracket of throttle and transmission actuator.
8. Throttle valve cable adjustment as follows:
First, use pliers to clip the hexangular position under throttle valve cable.Turn 60°~90°counterclockwise,
and lift throttle valve cable to make throttle valve cable adjustable move to top position, and then turn back
60°~90° clockwise, meanwhile, make it lock (See figure 7-4). Finally put accelerator pedal to end position.
When throttle valve makes "ka-ka" sound, the distance under the throttle valve should meet B=2~8mm. If not,
try again until the gap B=2~8mm under the throttle valve (see figure 7-5), if gap B=2-8mm, throttle valve cable
adjustment is finished.Central
