Procedure 11. Draining Sediment and
Sludge from the Fuel Tanks and the
Fuel Coarse Filter
Screw out the plugs (1, 4) and drain
sediment and sludge from the fuel tanks
(2) and filter (3), respectively until clear
fuel appears. Screw in the plugs.
Procedure 12. Checking the Tension
of the Alternator Driving Belt
The alternator belt tension is considered
to be correct if its sagging at the section
between the pulleys of the crankshaft
and the alternator is within 29 to 33 mm
when pushed with a force of 40 N (4 kgf).
To adjust the belt tension, turn the alter-
nator body such as to ensure the re-
quired tension. Tighten the plate attach-
ment bolt and nuts of the alternator at-
tachment bolts.
Procedure 13. Checking the Tyre Infla-
tion Pressure
Check the condition of the treads and air
pressure in the tyres. If necessary, bring
the pressure to the norm in accordance
with a number of loads and pressures
(see Section “Aggregating the Tractor
with Agricultural Machines and Imple-
ments” ).
Procedure 13a. Checking the Tighten-
ing of Fasteners of the Hubs and
Wheels
Check the tightening torques and, if ne-
cessary, tighten up:
• the bolts (1) of hubs of the rear wheels
with the torque of 360…500 N • m;
• the nuts fastening the rear wheels to
the hubs – 300…350 N • m;
• the nuts fastening the front wheels to
the flanges – 200…250 N • m;
• the nuts fastening front wheel webs to
the rim carriers – 180…250 N • m.
