The dust and dirt adhered to the radiator chip will reduce the cooling capability,
make the engine over hot, according to the situation, you can clean it ahead,even
clean it every day.
Blow out the dirt and dust with 196Kpa(2kgf/cm2)or less pressure compressed
air, if it is still dirty, you should use cleanser and water to wash thoroughly.
Before using the compressed air, please wear the protection glass to protect
your eyes. Prevent the dust or float pieces hurt your eyes.
Do not use the high-pressure tap and high-pressure air to wash by force, do
not use the brush to scrub, or the radiator chip will be damaged.
5.3.3.3Replace the air cleaner element
The damaged air cleaner element will make the air into the cylinder not through
the air cleaner element, it will damage the valve, cylinder, piston, piston ring
quickly.
If the element is plastered with dust, it will be hard to start the engine, the
power will drop, and there will be black smoke.
Replace the element terminally, and clean the shell, it's benefit to the engine
5.3.4Check for every 500 hours
5.3.4.1 Replace the fuel filter
Replace the diesel filter element terminally, before it choked by the grease
Turn off the switch of the fuel tank, disassemble the oil pipe, take off the
element, then clean the oil filter seat
Replace a new diesel element, install the fuel filter, pay attention to the terminal
cover of the filter element is sealed, prevent the un-filtration fuel enter into the fuel
injection pump.
Install in and out fuel pipe, turn on the switch of the fuel tank, advert drain out
the air empty. Otherwise the diesel engine will be hard to start or stop running
after starting.
5.3.4.2Replace the cooling water:
After the cooling water is not hot, drain it, avoid the splash hot water scalding
people.
If the cooling water or cooling liquid contain the rust and scale, the cooling
effection will be depressed.
The cooling water should be replaced once a year at least. Drain the cooling
water, and then add cleanly soft water.
5.3.4.3Check and adjust the valve clearance:
Make sure the valve is closed, before adjusting the gap, there will be clearance
Two methods to check or adjust
The 1-cylinder, 2-cylinder, 3-cylinder of the engine is
marked from flywheel end to gear room, is different from
the general method.
There are top dead center reticule of each cylinder, you
can look at it from dead center view port (Ö30) of
flywheel cover, the top dead center reticule of 1-cylinder
is marked on the belt wheel.
a. Single cylinder method: make sure the first cylinder locate in compression top
dead center then you can adjust the clearance between the intake and exhaust
valve(0.2~0.3)mm of 1-cylinder; turn the flywheel about 240
counterclockwise and then adjust clearance between the intake and exhaust
valve of 3-cylinder; turn the flywheel about 240 by counterclockwise last adjust
the 2-cylinder clearance. After all above, make sure put the adjusting bolt cap
together tight, or it will become loose, result in the unit can not work normally.
b.At twice method:
Put the 1-cylingder piston on compression top dead center, you can adjust the
following clearanace:
Cylinder order 1-cylinder
Adjustable valve Intake Exhaust
Rotate the flywheel about 240 by counterclockwise (rotary direction of the
engine), make the piston of 3-cylinder locate in compression top dead center
then adjust the other valve gap which is not adjusted
Cylinder order 1-cylinder
Adjustable valve
After all above, put the adjusting bolt cap together tight
5.3.4.4Check and adjust the injector
Check and adjust the injection pressure and quality of the spray on the test-bed,
the shape of spray as the following fig:
Check the injection pressure and quality of the spray
by
2-cylinder 3-cylinder
Intake Exhaust
2-cylinder 3-cylinder
Exhaust Intake Exhaust
