PART 8: MAINTENANCE AND SERVICE TIRES, WHEELS, AND RIMS
(R05/10) Y53-6032 – 177 –
WARNING!
Manual adjustment of automatic
slack adjusters is a dangerous practice that
could result in an accident involving death or
injury. It gives the operator a false sense of
security about the effectiveness of the brakes.
Contact the Service Department at your dealer-
ship if the stroke exceeds the above specifica-
tions. A stroke exceeding these values may
indicate a problem with the slack adjuster or the
brake foundation.

WARNING! Use only original equipment manu-
factured (OEM) components. Use of non-original
equipment could cause wheel breakage and
wheel separation from vehicle, which could
result in an accident causing death or personal
injury. Each mounting system is engineered
only for use with its correct mating part. Be sure
that properly matched components are used for
each type of mounting. The comparison chart on
Page 184
illustrates the differences between
parts used in hub-piloted mount and ball seat mount
applications. Only OEM supplied hub-piloted or ball-seat
mounted wheels may be used on this vehicle.
• If you are not fully qualified and not equipped
with the proper tools and equipment, do not
attempt to raise the vehicle or remove or install
the damaged tire and wheel assembly. Obtain
expert help. A person can be killed or seriously
injured and/or damage can result from using the
wrong service methods. Truck tires and wheels
should be serviced only by trained personnel
using proper equipment. Do not reinflate a tire
that has been run flat or is seriously low on air
without first removing the tire from the rim and
inspecting for damage.
• Follow OSHA regulations per section 1910.177.
• Follow all warnings and cautions contained
within the tire and wheel manufacturers litera-
ture.
• Only properly trained personnel should service
tire and rim assemblies.
Your tires are a very important part of your vehicle’s whole
braking system. How fast you can stop depends on how
much friction you get between the road and your tires. In
