Keep clean during oil change; the oil being used serves not only as a service fluid but at the
same time it performs lubrication of pump bearings; therefore the contamination of working fluid
with mechanical impurities or water causes the generation of burrs on the surface of journal
bearings and results in pump failures.
Change oil in the following sequence:
a) immediately after shutdown of the engine undo plug 10, open globe valve 9 and drain
heated oil;
b) replace filtering elements 17, wash the net filter;
c) wash the filler port 7 in diesel fuel and blow it;
d)fill oil into the hydraulic tank, start the engine and run for 2...3 minutes at a low
crankshaft rotational speed without rotating the steering wheel. The hydraulic distributor
levers shall be in the Neutral position;
