Seasonal maintenance
Combine seasonal maintenance with
regular maintenance operations. Mainten-
ance operations necessary during sea-
sonal maintenance are listed Table below.
Seasonal maintenance
Substance of works
During transition to autumn-winter season
(with settled average daily temperature be-
low + 5°
С
)
During transition to spring-summer season
(with settled average daily temperature
above + 5 °
С
)
Change summer oil grades for winter grades:
- In diesel casing;
- In the transmission case (CC, GB, RA)
- in a tank of HSC system

1) If all-season oil is used oil replacement in tanks of HSC and HLL systems shall be
performed only at MS-3 (after every 1,000 service hours).
Tractor maintenance under specific operation conditions
When operating the tractor under spe-
cific conditions (at lower temperatures, in
the desert, on sand and boggy soils, rocky
terrain), specified intervals and scope of
maintenance are preserved.
On top of that, below-listed works are in-
troduced additionally or performed more
frequently.
1. When operating the tractor in desert,
on sandy soils, at high temperatures and
dust, use enclosed method of filling diesel
with oil and fuel. Change oil in the air pu-
rifier sink after each three shifts.
During MS-1 perform the following opera-
tions additionally to those listed in mainten-
ance services operations table:
- check diesel oil, no mechanical impuri-
ties are allowed in oil. Replace the oil if ne-
cessary;
- service the air purifier after each 20
hours of tractor operation;
- Wash with stream of water or blow off
with air the water radiator core. Radiator
should be clean with no traces of oil on its
surface.
During M-2 wash fuel tank plug.
2.
When running the tractor under low
temperatures, make pre-start diesel
heating to up to 20-30
°
С
. At the end of
the shift fill tanks with fuel (at below 30°
С
use arctic fuel), and drain condensate from
cylinder. Fill the cooling system with anti-
freeze fuel.
3. When running the tractor on rocky
soils and in highlands examine each shift
visually driving gear and other tractor com-
ponents for possible damages, as well as
tightness of diesel casing plugs, rear axle
and FDA, fastening of driving wheels.
Check air tightness of the radiator plug of
the diesel cooling system.
In addition, in highlands operation condi-
tions to avoid disturbance of diesel function-
ing , make adjustment of the fuel pump with
a view to reduce its capacity in the following
range:
- at elevation of 1500-2000 m above
see level reduce capacity by 10%;
- at elevation of 2000 to 2500 m above
see level reduce capacity by;
- at elevation of 2500 to 3000 m above
see level reduce capacity by 20%; Opera-
tion at elevation over 3000 m is not rec-
ommended.
