O-ring sealing surfaces and pressure relief grooves must be kept
clean and free of rust and dirt. Failure to do so could 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 could cause individual fasteners to fail. Any of
these situations could cause serious injury or death.
Inspect inner rim half (2) for cracked, broken, rusted, pitted, bent, or loose studs (4).
Inspect valve core (6) for cracks or deterioration. Replace valve core (6) if cracked or deteriorated.
Inspect studs (4) for damaged or deformed threads. Replace studs (4) if threads are damaged or if
studs (4) are damaged or loose (para. 8-8).
Perform steps 11 and 12 only if valve core and insert were removed.
Inspect valve bore (7) for cracks or deterioration. Replace valve bore (7) if cracked or deteriorated.
Inspect insert (8) for damage. Replace insert (8) if damaged.
