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.
