8. Assemble axle flange to axle using a new
gasket. Apply sealant in stud area. After both
wheels have been assembled according to
above procedure, fill the differential with the
recommended lubricant to the proper factory
recommended level.
NOTE
During regular inspection, do not forget to
check lubricant level in differential. Clean
thoroughly or replace vent as required.
10. CHANGING A FLAT TIRE
In case of a flat tire, turn ON the hazard flashers
and bring the vehicle to a stop on the side of the
road. Apply the parking brake. Make sure the
vehicle is parked safely away from traffic. Set up
the triangular reflectors in accordance with
applicable highway regulations.
We suggest that you do not attempt to change a
wheel. First, the wheel and tire are very heavy
and usually there is no space available to put
the removed flat. Second, the wheel nuts,
especially those on inner dual, can become very
tight after being on for only a short time. Often a
heavy air wrench is required to get these nuts
loose. We suggest you get help via CB radio or
cellular phone. There are tire service trucks all
over the country that can bring a wheel and
make the change safely.
NOTE
Bus shell vehicles contain no spare wheel.
Access to compartment is obtained by pulling
the release handle located in the front service
compartment.
WARNING
The reclining bumper compartment has not
been designed for storage. Never leave loose
objects in this area since they may interfere
with steering linkage mechanism. Make sure
bumper is safely locked in place after closing
the compartment.
11. TIRE MAINTENANCE
The most critical factor in tire maintenance is
proper inflation (Fig. 6). 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.
NOTE
Bus Shells vehicles, before being converted,
are not at their maximum weight and tire
pressures are adjusted at lower level than the
maximum allowed appearing on the DOT
plate.
Tires pressure must be re-adjusted
once converted.
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.
11.1 INFLATION PRESSURE
•
Vehicles equipped with BERU TPMS
On vehicles equipped with the Beru Tire
Pressure Monitoring System (TPMS), it is better
to use the TPMS display as the primary
reference to judge when tire pressure need
adjustment.
The TPMS presents pressure readings of each
tire as a +/- deviation from the wanted target.
If a tire reads /- 3 PSI no adjustment is
needed.
If a tire reads -4 PSI and below, re-inflate by the
marked amount.
If a tire reads +4 PSI and above , deflate by the
marked amount.
Relying on the TPMS system is better than
relying on a hand gage since the TPMS is
temperature compensated and remain accurate
no matter if the tires are cold or hot.
Tires take up to 3 hours to get down to ambient
temperature after a ride. A common mistake
consist of checking pressure while the tires have
not fully cooled down which leads into under-
inflated tires. Relying on the TPMS eliminate this
mistake.
