b. Inspection and Cleaning
Do not use tire machine. Injury to personnel or damage to equipment
The following maintenance procedure applies to vehicles using load range
"D" tires and one-piece rubber runflats. Refer to paras. 8-4 and 8-4.1 for
maintenance instructions on bias tires and magnesium runflats.
Place wheel assembly in a tire inflation cage.
In all disassembly operations, ensure the tire is totally deflated before
removing wheel locknuts. Failure to follow proper safety precautions
could cause serious injury or death.
Remove valve core (8) from valve bore (7) and deflate tire (6). Run a piece of wire through valve
bore (7) to make sure it is not plugged.
When tire (6) is fully deflated, use a circular pattern and loosen twelve wheel locknuts (2) securing
rim halves (1) and (4) together. If you hear escaping air, do not proceed. Wait until the sound stops
and recheck valve bore (7). When you are certain the tire (6) is fully deflated, proceed to remove
wheel locknuts (2). Discard locknuts (2).
