0B-28 MAINTENANCE AND LUBRICATION
Maintenance
1) To equilibrate the wear on the tyres, exchange them
periodically as showed in the schemes.
NOTE:
• Fitting of new tyres, must be done with equivalent to
the original ones.
• Check the tyres air pressure when they are cold; the
pressure is specified in owners hand book.
CAUTION:
Do not use tyres with different characteristics in the
same vehicle.
Wheels and Wheels Nuts (Item 4.10)
Inspection
1) Inspect the wheels to check for dentings, deformations or
cracks.
2) When dismantling a wheel, be sure there is no corrosion in
the contact area neither in the wheel nuts; otherwise,
suppress it.
3) Tighten the nuts to the adequate torque and in the order
indicated in the graphic.
Wheel Nuts Tightening Torque:
11 ÷ 17 kg-m (110 ÷ 170 Nm)
NOTE:
• Substitute the wheel showing any damages.
• Clear up the existing corrosion around the contact
areas metal with metal; otherwise, deficient contacts
could set in leading later on to untightening of the
wheel.
