At the engine cold start, white smoke may be coming out of the exhaust pipe for some
time, which is not a fault as the engine is running overcooled. Do not heat up the air
sucked in front of the air cleaner with open flames.
Do not start the engine by towing a tractor/ agricultural machine.
2.3.3 Diesel engine shutdown
Before the engine shutdown, let it run for 3-5 minutes, first at the medium, then at the
maximal idle speed in order to reduce the cooling liquid and oil temperatures. Not ob-
serving this rule will cause the turvocharger going out of operation.
Stop the engine by turning the ignition lock key into “0” position. Disconnecting the ve-
hicle mass from the accumulatory battery “plus” wire is not allowed within of not less
than 1 minute after the engine ignition swutch-off and the engine shutdown.
Turn the accumulator battery switch off after the engine shutdown.
2.3.4 Diesel engine perationsl run-in
Diesel engine must be run-in for rubbing parts confrication before the engine going into
operation. Diesel engine operation under full load without prior operational run-in is not
allowed. Diesel engine operational run-in is done the engine final user.
As soon as the engine is ready for operation, start it and having made sure it works
properly, begin the run-in.
Diesel engine running-in at the idle is done during 5 minutes with gradual raising the en-
gine speed up to 1600 min
1
−
, then run the engine in under load for 30 hours.
The engines installed in tractors/ combine harvesters run-in under load is done while
performing jobs not requiring tractive force, gradually raising the load from lower to
higher gear.
With the engine run-in complete, perform the following technical maintenance:
- check and, if necessary, tighten the cylinder heads bolts;
- check and, if necessary, adjust the gap between the valves and rockers;
- clean the centrifugal oil filter rotor;
- replace the oil filter;
- replace the oil in the engine oil sump;
- pour the sediment out of the fuel pre-filter;
- check and, if necessary, adjust the drive belts tension;
- check and, if necessary, tighten the outer threaded connections.
Exhaust gases at the oulet have the temperature of 600…800
℃
, so the
thermal damage to the exhaust manifold paintwork does not a signify disturbances in
the engine workflow.
2.3.5 Diesel engine operation in winter conditions
Diesel engine operation is complicated at low ambient air temperatures. To ensure con-
tinuous and troublefree operation in the winter period, which start with the ambient tem-
peratures lowering to +5°
С and lower, get the engine ready for operation in the winter
mode well in advance. For that purpose, do the scheduled technical maintenance, adding
the seasonal technical service operations. A tractor engine compartment must have a
