DE08TS Diesel Engines
Major Maintenance
Injection nozzle
1.
Install a nozzle on the nozzle tester.
2.
If the inspected injection pressure is less than the
specified value, adjust using the adjusting shims.
3.
Check the atomizing state and replace it if abnor-
mal.
Fuel injection pump
1.
Check the housing crack, damage etc. and
replace it if abnormal.
2.
Check if the idle operation and speed regulating
lever’s sealing is removed.
3.
The adjustment and testing of fuel injection pump
should necessarily be done at the test bench.
Air removal of fuel system
The suction room of fuel injection pump has the func-
tion of air removal continuously during the operation
through a relief valve.
In case that the suction room lacks fuel at all, for
instance, in case of new installation of injection
pump, after loosening the air removing screws of
cartridge filter respectively, remove the air by operat-
ing the manual pump of fuel supply pump until bub-
ble will disappear.
Fuel supply pump
Every time of engine oil replacement, the fuel strain-
er installed at the fuel supply pump should be
removed and cleaned.
Turbocharger
The turbocharger needs not arty special equipment.
Every time of engine replacement, a leakage or clog-
ging of oil pipes should be inspected. Air cleaner
should be maintained carefully for nut or foreign
material not to get in.
Periodic inspection should be applied on the com-
pressed air and exhaust gas pipes, For leaking air
will bring the overheat engine, an immediate repair
must be done.
During the operation that is surrounded by the dust
and oil mixed air, frequent cleaning must be done on
the impellers.
Tear down the impeller casing (attention: be careful
not to bend) and must clean with non-acid solvent
solution.
If necessary, use plastic scraper If impeller is severe-
ly polluted, dip the impeller into solution and may be
better to clean it with stiff brush.
Then one thing to beware is to dip only impeller part
and so do not support by impeller but bearing hous-
ing.
Starting motor
In case of engine maintenance, clean pinion and ring
gear thoroughly putting in the fuel, and coat them
with grease.
Also, In case of washing engine (room) and so forth,
inspect the wiring state being careful for water not to
get in.
