Preventive Maintenance
WARNING! Improperly mounting and demounting
tire and rim assemblies is dangerous. Failure
to observe proper precautions could cause the
tire-rim assembly to burst explosively, causing
serious injury or death. See the wheel manufacturer's
literature for the proper way to mount and
demount your tires and rims. Follow their precautions
exactly.
Comparing Hub Piloted and Ball Seat Parts
WARNING! Do not mismatch wheel components.
Equipment that does not exactly match original
specifications or that is mismatched could
cause the wheels to break and separate from the
vehicle. The resulting accident could be very
serious. Each mounting system is engineered
for use only with its correct mating part. Be sure
properly matched components are used for each
type of mounting.
DEMOUNTED RIMS
The following comparison (Table 9, ”Comparing Hub-piloted
and Ball-seat Wheels”), shows the difference between parts
used in hub pilot mount and ball seat mount applications.
