Action 8. Checking the tension of the
belt for driving the engine cooling
system fan
Check the belt for the presence of the
traces of wear or damage. If necessary,
replace it.
To check the tension of the belt of the
engine alternator with an elongated
shield, apply the force of 40 N at the
middle of the belt section “alternator pul -
ley – water pump pulley” (1). The deflec -
tion shall be within 6-10 mm. If neces -
sary, 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 sec -
tion “alternator pulley – crankshaft pulley”.
The belt deflection shall be within the
range 15…20 mm under the force of
about 40 N applied to the middle of the
section.
Action 9. Rear wheel hubs
Check the tightening torques and tight-
en them, if necessary, with the following
torques:
• the bolts (1) of the rear wheel hubs:
360…500 N•m;
• the nuts for fastening the rear wheels
to the hubs: 300…350 N•m;
• the nuts for fastening the front wheels
to the flanges: 200…250 N•m;
• the nuts for fastening the disks of the
front wheels to the rim supports:
180…240 N•m.
Action 10. Air pressure in the tyres
Check the tread condition and air pres -
sure in the tyres. If necessary, adjust the
pressure according to the recommenda -
tions given in the section “Operating In-
structions”.
