Check connection bolt
Check the bolts for Deutz diesel
engine, generator, injector and intake/exhaust manifold and the connection of
bolts and hoses, re tighten them if necessary.
Tighten cylinder head
bolts
Loosen the cylinder head bolts
about 1/4 of a rotation when engine warming, and then tighten them up with a
force of 200+ 10 Nm immediately according to the sequence as the following figure.
Check and tension the
V-belt
Press the V-belt with hand, the
distortion should not be more than 10-15mm, otherwise change the belt with a
new one.
If tension the belt through
generator, loose bolt 1 and bolt 2 firstly, stain the generator outwards, then
tighten up bolt 1 and bolt 2 and check the belt by hand.
If tension the belt through
tension pulley, loose the bolt 3 and bolt 4 on bracket 5, stain the tension
pulley bracket, and then tighten up bolt 3 and 4 and then check the belt by
hand.
Caution: Change the damage or
oiled belt.
Change oil
A. Start the engine and stop it
after reaching the operation temperature.
B. Place an oil tank under the
engine.
C. Screw out the drainage screw
plug 1, pay attention the seal ring on the screw plug.
D. Drain off all oil.
E. Screw on the screw plug 1 with
seal ring.
F. Fill up clean oil.
Replace oil filter
A. Disassemble the oil filter 1
with special wrench.
B. Coat some oil on the seal ring
2 and tighten up the oil filter by hand.
C. Check the oil filter for
tightness in running -in.
Check valve clearance
A. Remove cylinder head cover.
B. Make the piston reached the
firing TDC.
C. Check the clearance between
rocker arm and gauge 1. adjust the clearance according with screw 3.
E. Holding the position of screw
3 and tighten nut 2.
F. Check the other clearance with
feeler gauge 1.
G. Set up rocker arm cover and
tighten the screws. The rocker arm cover seal side should be faced with the
gasket.
Caution: Adjust valve clearance
according to the firing order to avoid turning crankshaft unnecessarily.
Change fuel filter
1. close the valve on fuel
circuit.
2. Turn the special tools of fuel
counter-clockwise. Disassemble the fuel filter 1.
3. Before mounting new filter,
coat lubricating oil on seal ring 2.
4. Tighten the new filter by
hand.
5. Open the valve on fuel circuit.
6. Degas the fuel system.
7. Check the sealing of fuel
filter.
Clean breather body
1. Loosen the hexagon nut or
screw 1.
2. Loosen hose clip 2.
3. Disassemble breather body 3.
4. Pay attention to the O seal
ring.
5. Clean the breather body in
diesel.
6. Mount the breather body,
change new O seal ring, if necessary.
7. Tighten the hose clip 2.
8. Tighten the hexagon nut or
screw 1.
Clean intercooler
In the operation of intercooler,
if enlarged cooled air resistance and the decreased difference in temperature
affect the performance of diesel engine, the intercooler should be cleaned.
Run-in
If the engine is in standby or
emergency state, run it once a month so as to prevent it from corrosion damage.
1. After starting, check the
instrument meter at once, put 1/3 load on the engine.
2. After running for 10 minutes,
increase to 3/4 load.
3. After running for another 10
minutes, increase to full load.
4. Check the sealing of the
engine.
5. Run the engine at 1/3 load for
10 minutes.
6. Unload and stop the engine.
Engine maintenance
If the engine stops for a long
time (for several weeks), the following protective measures must be taken so as
to prevent it from corrosion damage:
Operating order:
1. Rinse the exterior of diesel
engine.
2. Drain off the oil inside the
engine and the fuel in injection pump.
3. Add corrosion preventive to
the engine.
4. Drain off fuel.
5. Mix fuel oil and corrosion
preventive on the scale of 9:1.
6. Fill the fuel tank with the
mixture above.
7. Drain cooling water.
8. Add emulsifiable corrosion
preventive to the cooling water according to the degree of 5%.
9. Add above compound to cooling
system, and vent air from the system.
10. Start the engine and run it
for 10 minutes.
11. Stop the engine and turn
flywheel several circles to make the combustion chamber sufficiently wet.
12. Drain off cooling water.
13. Smear exposed parts of the
engine with corrosion preventive grease.
14. Close the intake manifold and
exhaust manifold.
15. Repeat the above operations
after three months.
When the engine is demanded to
put into service, you should:
1. Drain off corrosion preventive
and mixed fuel.
2. Add fuel and coolant, vent air
from the fuel system and cooling system.
3. Add fuel and coolant, vent air
from the fuel system and cooling system.
4. Remove corrosion preventive
grease on the exterior parts.
5. Open the ports of intake
manifold and exhaust manifold.
We can provide 24KW to 550KW Deutz diesel generator with good quality and low price.
