PREVENTIVE MAINTENANCE TIRES AND WHEELS 00118 DISK WHEEL 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 DEMOUNTED RIMS Crisscross Tightening Sequence 02951 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 causing death or personal injury. 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. The following comparison (Table 8, ”Comparing Hubpiloted and Ball-seat Wheels”), shows the difference between parts used in hub pilot mount and ball seat mount applications.
