The operation of the diesel at the altitude exceeding 9,836 ft (3,000 m) above sea level is
not recommended.
2.2.1.2. Starting the engine by means of the starter
When starting the diesel engine:
- set the gear shifting lever of the tractor (machine) to the neutral position;
- set the “ground” switch to the ON position;
- set the fuel pump control lever to the position corresponding to the maximum feed;
- switch on the electric torch pre-heater by rotating the switch to the I position;
- after 30-40 s, during which the pre-heater spiral will warm up, disengage the clutch of the trac-
tor (machine), switch on the starter by setting the switch to the II position and start the diesel en-
gine;
- after starting the diesel engine engage smoothly the clutch.
The duration of the continuous run of the starter shall not exceed 15 s. If the diesel en-
gine fails to start, repeat the starting procedure 30-40 s later. If the diesel engine fails to start after
three attempts, locate and eliminate the trouble.
When the diesel engine is warmed up as well as in summer it can be started without turn-
ing on preliminarily the electric torch pre-heater by turning the switch directly to the II position
without holding it in the I position.
2.2.1.3. Stopping the diesel engine
Before stopping the diesel engine after removing the load, let it work for 3-5 min first at
the medium and than at the minimum idling speed for reducing the temperature of the coolant and
oil and then stop the diesel engine by setting the fuel pump control lever to the position corre-
sponding to the fully shut fuel feed.
After stopping the diesel set the «ground» switch to OFF position.
Failure to comply with these rules when stopping the D-245 diesel and its modifications
can cause the damage of the turbo-supercharger.
2.2.1.4. Operational running-in of the diesel
The operation of the diesel under loading without preliminary running in is not al-
lowed.
The diesel engine must be run-in by the operating organization. It is recommended to
stick to the following sequence of works: preparing the diesel engine for running in, running in the
engine on idling and under load for 30 hours and preparing the engine for operation.
When preparing the diesel for operational running in follow Section 2.1 "Pre-Operation
of the Diesel Engine".
Start the diesel engine and, having made sure that it is running properly, proceed to run-
ning in. First, run in the engine on idling for 5 minutes with increasing smoothly its speed up to
the maximum value.
Run in the engine installed in the tractor under load by performing light transport (trailer
with the load of 2-3 t (4,405-6,608 lb)) and field (harrowing, sowing, ground treatment with a
cultivator, etc.) works while increasing the load on various gears. Overloading the diesel engine
is not allowed.
After running in the diesel engine perform the following operations:
- check the bolts fastening the cylinder head for tightening;
- check the clearance between the valves and rocker arms;
- clean the rotor of the centrifugal oil filter;
- replace the oil in the engine crankcase;
