WHEELS, RIMS AND TIRES
Figure 5. - Cross Section of Inboard and Outboard
Mounted Drum
PRECAUTIONS
Always loosen rim clamps before complete removal of
nut from stud (cast spoke wheels). With loosened nuts
on stud, strike clamps with a heavy hammer and be sure
each clamp is loose.
Always deflate tires completely before removing locks or
side rings.
Always inspect and clean all parts before assembly.
Always inflate tires in a safety cage.
Always use a "clip-on" air chuck with remote control
valve to inflate tires.
Never strike cast spokes of wheel assembly when
loosening rim clamps.
Never mix rim side rings or lock rings of different types or
size.
Never use cracked, bent or badly rusted parts.
Never reinflate flat tires on vehicle - use the spare.
Never add air until certain each side or lock ring is fully
seated.
Never hammer side or lock ring on a partially or fully
inflated tire.
When installing the tire and rim assembly on disc braked
axles, make sure the tire valve stem clears the brake
caliper. The use of an I.H. valve stem retainer or tire
manufacturer’s stem-forming tool are the only acceptable
methods of obtaining clearance when necessary.
REMOVE AND REINSTALL
When servicing wheels, different procedures will be
required for particular service applications.
Examples:
Tire service will require removal of wheel and tire on
vehicles with disc wheels. On vehicles with cast spoke
wheels, tire and rim assembly will be removed for tire
service.
Brake service (except disc brakes) will require different
procedures
depending
upon
inboard
or
outboard
mounted drums.
A.
Vehicles with cast spoke wheels or disc wheels
and inboard mounted brake drums (single or
dual tires): remove wheel, hub and drum as an
assembly.
B.
Vehicles with disc wheels (single or dual tires)
with outboard mounted brake drums: remove
wheel or dual wheels. Then remove brake drum
leaving hub assembly intact on vehicle. Wheel
bearing service will not be required with this
application.
Refer to the GENERAL topic for further identification of
wheels and to application of inboard and outboard
mounted drums.
When installing wheel, hub and drum assemblies, refer
to the following: WHEEL BEARING ADJUSTMENT,
WHEEL SEALS, and WHEEL BEARING.
