Use a 0.0015 in. (0.038 mm) thickness gauge to detect gaps. If gaps are detected, disassemble and reassemble wheel assembly and recheck for gaps. If gaps are still detected, replace outer rim half (3). WARNING • Never inflate a wheel assembly without having checked wheel locknut torques to ensure the wheel locknuts are tightened to specifications. An assembly with improperly tightened locknuts could separate under pressure, resulting in serious injury or death. • Always use a tire inflation cage for inflation purposes. Stand on one side of the cage, during inflation, never directly in front. Keep hands out of the cage during inflation. Inflate assembly to recommended pressure, using a clip-on air chuck. Do not exceed 50 psi (345 kPa) cold inflation pressure. Failure to follow these instructions may result in serious injury or death. 20. Place assembly in safety cage and inflate front and rear tires to recommended tire pressure (TM 9-2320-280-10). 21. Check for leaks around rim edges (4), insert (6), and valve bore (5) with soapy solution. FOLLOW-ON TASK: Balance tire (para. 8-9). TM 9-2320-280-20-2 8-24.10 Change 2 8-5.1.
