NOTE The following maintenance procedure applies to vehicles using bias ply tires and two-piece magnesium runflats. Refer to paras. 8-4.1, 8-5, and 8-5.1 for maintenance instructions on radial tires and rubber runflats. 1. Place wheel assembly in a tire inflation cage. WARNING 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. 2. Remove valve core (4) from valve stem (3) and deflate tire (6). Run a piece of wire through valve stem (3) to make sure it is not plugged. 3. When tire (6) is fully deflated, remove wheel assembly from tire inflation cage and place flat on floor with valve stem (3) facing up. 4. Using a circular pattern, loosen eight wheel locknuts (1) securing rim halves (2) and (8) together. If you hear escaping air, do not proceed. Wait until the sound stops and recheck valve stem (3). When you are certain the tire (6) is fully deflated, proceed to remove wheel locknuts (1). Discard locknuts (1).
