TYRE MAINTENANCE
Wheel Nuts
Figure 211
See your SERVICE SCHEDULE for the service interval
to check the wheel nuts [Figure 211]. (See SERVICE
SCHEDULE on Page 111.)
When installing
wheel nuts, tighten to 217 N•m (160 ft-lb)
torque.
When checking
wheel nut torque, set the torque wrench
to 190 N•m (140 ft-lb) to prevent over-tightening.
Rotating
Check the tyres regularly for wear, damage and pressure.
Figure 212
Rear tyres usually wear faster than front tyres. To keep
tyre wear even, move the front tyres to the rear and rear
tyres to the front [Figure 212].
It is important to keep the same size tyres on each side of
the loader. If different sizes are used, each tyre will be
turning at a different rate and cause excessive wear. The
tread bars of all the tyres must face the same direction.
Recommended tyre pressure must be maintained to
avoid excessive tyre wear and loss of stability and
handling capability. Check for correct pressure before
operating the loader.
Mounting
Tyres are to be repaired only by an authorised person
using the proper procedures and safe equipment.
Tyres and rims must always be checked for correct size
before mounting. Check rim and tyre bead for damage.
The rim flange must be cleaned and free of rust.
The tyre bead and rim flange must be lubricated with a
rubber lubricant before mounting the tyre.
Avoid excessive pressure which can rupture the tyre and
cause serious injury or death.
During inflation of the tyre, check the tyre pressure
frequently to avoid over inflation.
