8-4.1. RADIAL TIRE, WHEEL, AND RUBBER RUNFLAT MAINTENANCE (24-STUD) (Cont'd)
O-ring sealing surfaces and pressure relief grooves must be kept
clean and free of rust and dirt. Failure to do so may cause the
wheel assembly to separate under pressure, causing serious injury
Using wire brush, clean studs (4). Clean all dirt and foreign material from rim halves (1) and (2)
with soap and water and allow to air-dry. Ensure O-ring sealing surfaces (5) and pressure relief
grooves (3) on rim halves (1) and (2) are smooth and clean.
Inspect rim halves (1) and (2) for cracks, bent sealing surfaces (5), or oversized mounting holes.
Replace rim halves (1) or (2) if cracked, bent, or if mounting holes are oversized.
Never use wheel assemblies with studs which are damaged, loose,
or have damaged threads. Damaged studs can cause improper
assembly, which may cause individual fasteners to fail. Any of
these situations may cause serious injury or death.
Inspect inner rim half (2) for cracked, broken, rusted, pitted, bent, or loose studs (4) and studs (4)
with damaged, mutilated, or deformed threads. Replace studs (4) (TM 9-2320-387-24-1) if damaged,
loose, or threads are damaged.
Inspect insert (6) for damage. Replace insert (6) if damaged.
Refer to TM 9-2610-200-14 for maintenance and repair of tires.
