in the fuel tank. With that job done and rectifying the discovered faults, you may begin the
diagnostics.
The diesel engine controllable parameters – according to item 1.1.2.2, Table 3.
Measurement means for determining the engine controllable parameters – according to
item 1.1.2.3, Table 4.
Upon the diesel engine warranty period expiration, it is permissible to determine the en-
gine output by the non-braking method. The non-braking method allows to determine the
output and fuel economy by the effective fuel consumption. At that, there is no necessity to
dismantle the engine from the machine.
When testing the engine with the non-braking method, connect a
КИ-8955 or КИ-8940
type fuel consumption meter
to the low pressure fuel system and mount a КИ-5653 type
load imitator on the air intake pipe. Connect piezometer to the air supply system inlet
branch.
The engine is started and heated up to the normal heat condition and, at set modes, deter-
mine the effective fuel consumption by which the engine output is finally determined.
If necessary, to estimate the technical condition of parts and units (beraing units, belt
drives, shafts) not having generalized indicators they use the size parameters (gaps, clear-
ances, lifts), try the parts and units or visually inspect them. All faults discovered by tech-
nical diagnostics must be rectified by current repair or overhaul.
3.1.5 Proofing (reproofing) for storage
Depending on diesel engines scope of delivery agreed in contracts with customers, the en-
gines are proofed for storage from 6 months to one year periods. The particular proofing
period is specified in an engine passport.
With the engine storage period exceeding that in the passport, it must undergo reproofing.
Engine reproofing after a 6 months storage must be done for a one year period. Repeated
reproofing under a 6 months standard is not permissible.
Enegine proofing as part of a tractor/machine for a short storage period (10 days to 1
month) is done as described in item 3.1.5.1.
Enegine proofing as part of a tractor/machine for a long storage period (over 1 month) as
well as reproofing for over 6 months is done as described in item 3.1.5.2.
It should be noted that after the engine start depreservation of its inner cavities, cooling
and fuel supply systems takes place.
3.1.5.1 Engine proofing before short storage
Drain motor oil from from the engine oil sump into suitable vessel at the ambient tempera-
ture and the engine parts temperature not higher than 60º
С.
Put and screw the oil drainage plug into the oil sump tray.
Fill the oil sump with motor oil to the appropriate level as recommended by the
Chemmotological Chart (Annex “
А”).
Fill the fuel tank with the recommended fuel (Annex “
А”).
Let the engine run without load for 2 minutes at 1200 min

.
Do not drain the oil from the oiling system and the fuel from the engine power system after
the engine shutdown.
Check the air cleaner and, if necessary, service it.
