IT IS ABSOLUTELY PROHIBITED
to operate with clogged or ice-covered grill of the air intake
pipe cover and without free gas outlet from the exhaust pipe, as it leads to the ingress of
exhaust gases through the dust suction pipe to the air cleaner cassettes.
7.5.4 Cooling system maintenance
Filling and check of the cooling fluid:
a) perform filling the tractor cooling system through the filler port and plug of the expansion tank
to the level of 60
–80 mm from the upper plane of the filler port of the expansion tank plug;
during operation avoid any drop of the level in excess of the permissible value.
b) avoid leaks of cooling fluid;
c) in order to prevent prior clogging of the cooling system perform filling and drain of cooling
fluid into a clean reservoir avoiding the ingress of oil products therein;
d) a drain valve located on the pipe connecting the radiator to the water pump is provided under
the radiator for draining the cooling fluid on tractors with 8481.10/-02/-04, OM457LA (Mercedes)
engines. On the tractor with
ЯМЗ-238НД5 engine, the valve is located on the heating boiler.
There is a drain plug on the left-hand block of 8481.10/-02/- 04,
ЯМЗ-238НД5 engines;
e) perform filling and refill of the cooling system only using automotive cooling fluids specified in
the instruction for the engine.
ATTENTION!
In order to avoid overheating of the cooling fluid, it is necessary to see for
the absence of fouling of the water radiator plates. To this end, when working in dusty
conditions, it is necessary to perform radiator blowdown with compressed air under the
pressure of 5...7 kgf/cm
2
during every shift on both sides
– from the radiator front and
from the fan casing side.
In case of repeated overheating of the engine, it is necessary to thoroughly check the
condition of the radiator core. To this effect, it is necessary to free the fastening of
condenser of the air conditioner assembly with the fan from the frame and carefully throw
out it forward, then check the absence of clogging between the radiator plates by inside
light inspection using a portable lamp. If necessary, perform blowdown or (in case when
dirt is not removed by means of blowdown) wash the radiator core with water under the
pressure of 5...7 kgf/cm
2.
In order to enhance the effectiveness of cleaning of the radiator block cores from dust, chaff,
etc., the possibility of separation of the oil radiator block 1 from engine cooling block 2 is
provided on the tractors.
