9.1 COMPACT BEARING AXIAL PLAY AND
GREASE CHANGE.
Bearing axial play verification and grease
change must be performed periodically, refer to
Section 11 “Rear Axles” for maintenance,
removal and reinstallation instructions and
Section 24a “Lubrication and service schedule “
for proper grease selection and service intervals.
10. TIRE MAINTENANCE
The most critical factor in tire maintenance is
proper inflation (Figure 25). No tire is impervious
to loss of air pressure. To avoid the hazards of
under inflation, always maintain tires at their
recommended inflation pressure. Improper
inflation decreases tire life.
An under inflated tire builds up heat that can
cause sudden tire destruction, resulting in
improper vehicle handling and possible loss of
vehicle control. At least once a week, before
driving (when tires are cold), check inflation
pressure on all the tires, including the spare tire.
This is especially important in cases when
different drivers operate the vehicle.
WARNING
Failure to maintain correct tire inflation
pressure may result in sudden tire destruction,
improper vehicle handling, and will cause
rapid and irregular tire wear. Inflation pressure
should be checked weekly and always before
long distance trips.
10.1 INFLATION PRESSURE
The condition and pressure of the tires can
greatly affect both useful tire life and road safety.
At regular intervals, verify the tire pressures.
Use an accurate tire pressure gauge when
checking inflation pressures. Never exceed the
maximum inflation pressure specified on each
tire.
NOTE
Inflation pressure should be checked when
tires are cold. Cold tire inflation pressure can
be measured when a vehicle has not been
driven for at least 3 hours or less than 1 mile
(1.6 km). Driving, even for a short distance,
causes tires to heat up and air pressure to
increase. Check inflation pressure on all tires
(including the spare tire) using an accurate tire
gauge.
NOTE
The recommended tire inflation pressures are
given in the applicable documents supplied
with the vehicle. In addition, cold tire inflation
pressures are listed on the Department of
Transport's certification plate, affixed on the
panel behind the driver’s seat. For special tire
selection, a “PREVOST COACH SPECIAL
SPECIFICATION” chart is supplied with the
vehicle and is affixed on the left wall near the
driver’s seat. Remember, tire inflation
pressure must be adjusted according to
vehicle loading - see table in "Coach Final
Record"
CAUTION
Never bleed air from hot tires as tires will then
be under inflated. Use an accurate tire gauge
to check pressures (Do not kick tires as an
inflation check. This is an unreliable method).
