Always use a tire inflation cage and a clip-on airchuck for tire inflation.This task covers:a. Disassemblyc.Repairb. Inspection and Cleaningd. Assemblya. DisassemblyWARNINGDo not use tire machine. Injury to personnel or damage toequipment may result.NOTEThe following maintenance procedure applies to vehicles usingbias ply tires and two-piece magnesium runflats. Refer toparas. 8-4.1, 8-5, and 8-5.1 for maintenance instructions on radialtires and rubber runflats.1.Place wheel assembly in a tire inflation cage.WARNINGIn all disassembly operations, ensure the tire is totally deflatedbefore removing wheel locknuts.
