The fuel line of the engine fuel system is as shown in figure 3.2.2 followed:
To eliminate the air in the low-pressure fuel line, loosen the connector of the intake
pipe in the VE dispensing pump at first, then expel the air from the fuel.
Inspect the connector of the VE pump return pipe. If there is a lot of fuel
overflowed and no air bubble occur, It indicates that there is no air in the low-
pressure fuel line.

3.2.3 Eliminate the air in the high-pressure fuel line.
The high-pressure fuel line begins from VE dispensing pump, through high-
pressure fuel pipe, to the fuel Injector.
Method of the treatment: loosen the connector where the high-pressure fuel pipe
connects with fuel injector, then start the starter motor and let it run at low speed
until the fuel overflows around the connector, finally tighten it. If there is still some
air in the high-pressure fuel-pipe, the engine won't start.
(7) Check the air cleaner
If the dust is drawn into the air cleaner and clings to air cleaner parts, it will affect
the output of the engine sooner or later. When the combustion chamber draws the
dust in, it will accelerate the worn of the moving parts and cause the engine not to
run normally. When you run the engine in the dusty place, the service interval
should be shortened as possible as you can, paper air cleaner element.
Loosen the wing nuts in center of air cleaner, remove the air cleaner cap, then get
out the paper element inside the air cleaner.
Blow and clean the inner surface of the parts using the compressured air (below
0.2 Mpa). Clean the dirt and dust clinging to the surface.
If the elements are dirty or broken always, replace them with new elements.
Reinstall the paper element after cleaning the dirt and dust clinging to the air
cleaner and chassis.
7.3 The technical maintenance after the engine works 1000 hours
Repeat those items as technical maintenance after working 500 hours , then
perform the following maintenance items:
1. Check the tightness degree of the bolt in the connecting rod and main bearing.
2. Check the seal of the inlet and exhaust valve. If necessary, machining the
surface of the valve seat over again.
3. Check the starter motor and generator. If necessary, add the lubricating oil, and
run the engine at idle speed after reinstalling it. Add grease to the bearing before
putting the engine to use.
4. Check each part of the diesel engine.
5. Reinstall the parts removed in the maintenance course to primary position,
eliminating the potential fault.
