Defect, external manifestation,
cause
Way of elimination
Diesel engine fumes in all operating modes - blue fume is emitted from the

Ingress of oil into the combustion chamber as
a result of wear of cup-piston group compo-
nents
Replace the worn-out parts of the cu
-piston
group.
Excess of oil in the diesel engine crankcase. Drain the excessive oil, having set the level
against the upper mark of oil-measuring rod.
The diesel en
ine overheats
There is not enough cooling fluid in the die-
sel en
ine.
dd cooling liquid up to normal level.
Radiator is polluted outside. Clear radiator.
Presence of dirt and scum in cooling sys-
tem.
Clean and wash out cooling system from
dirt and scum.
Valve of thermostat does not open com-
pletel
.
Replace thermostat.
Insufficient tension of belt of fan
d
ust tension of belt.
Oiling of fan driving belt and pulleys. Remove driving belt and remove oil tracks
from belt surface and pulleys.

ine below admissible
Pressure index is defective. Replace pressure index after check of oil
pressure b
control manometer.
Tightness of connections of oil pipelines is
broken.
Reveal place of seal failure and restore it.
Oil pump is defective. Reveal defects and eliminate.
Oil level in diesel engine case is below ad-
missible.
dd oil up to top label of oil meter core.
Jamming of safety valve in diesel engine
case of oil filter.
Wash out valve and adjust pressure in sys-
tem of
reasin
.
Limiting wear of interfaces of neck of diesel
engine case — bearings.
Remove defect.
The en
ine overspeeds
Stop the engine immediately by shutting off fuel or air feed. Remove the fuel pump from
the engine and send it to a specialized workshop to determine the cause and eliminate
the fault.

there is no specific sound of hi
h tone
Presence of extraneous subjects interfering
rotation of rotor.
Remove glow tube and outlet pipe, remove
extraneous sub
ects.
Jammin
of rotor in bearin
. Replace turbocompressor.
Increased emission of oil from the side of
compressor or turbine, infringement of
tightness of oil compaction of turbocom-
pressor.
Remove turbocompressor from diesel en-
gine and send to workshop for repair.
