8. Inspect outside of tire for sidewall damage. Replace tire if
damaged.
9. Inspect tread for puncture damage. If damage is too
extensive for patch repair, replace tire.
WARNING: O-ring sealing surfaces must be kept clean
and free from rust and dirt. Failure to do so could cause
the wheel assembly to separate under pressure causing
serious injury or death.
10. Using wire brush, clean wheel attaching studs. Clean all
dirt and foreign material from rim halves with soap and
water and allow to air dry. Ensure O-ring sealing surfaces
on rim halves are smooth and clean (Figure 6-8).
11. Inspect rim halves for cracks, bent sealing surfaces, or
oversized mounting holes. Replace rim halves if cracked,
bent, or if mounting holes are reamed.
