Operation 6. Draining sediment from
fuel tanks and fuel coarse filter
Open the drain plugs (1) of the fuel tanks
(2) and the drain plug (3) of the filter and
drain sediment until clean fuel appears.
Drain sediment into a special container
and dispose of it properly.
Close the drain valves after appearance of
clean fuel without water and dirt.
Operation 7. Checking tension of fan
belt of engine cooling system
Check the belt for traces of wear or dam-
age. If necessary, replace it.
To check tension of the belt of the engine
alternator with an elongated shield, apply
a force of 40 N approx. to the middle pint
of the belt section “alternator pulley to wa-
ter pump pulley” (1). The deflection must
be 6 to 10 mm. If necessary, adjust the
belt tension by rotating the alternator body,
having loosened the lath fixing bolt and the
alternator fixing nuts, and then tighten
them.
NOTE:
When fitting a normal alternator
shield, check the belt tension on the section
“alternator pulley – crankshaft pulley”. The
belt deflection shall be within the range
15…20 mm under a force of 40 N approx.
applied to the middle of the section.
Operation 8. Rear wheel hubs
• Check tightening and, if necessary,
tighten the bolts (1) fastening the real
wheel hubs (four bolts on each hub)
with a torque spanner. The tightening
torque must be 300 to 400 N•m (30 to
40 kgf•m).
• Check and adjust as necessary the
nuts of:
• front wheels to a torque of 200 to 250
N•m
• rear wheels to a torque of 300 to 350
N•m
• fastening of the disks to the rims to a
torque of 180 to 240 N•m.
