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 if improperly
disassembled, causing serious injury or death.
Using wire brush, clean studs (16). Clean all dirt and foreign material from rim halves (12) and (14)
with soap and water and allow to air dry. Ensure O-ring sealing surfaces (17) and pressure relief
grooves (15) on rim halves (12) and (14) are not cracked, bent, and do not have oversized mounting
Inspect rim halves (12) and (14) for cracks, bent sealing surfaces, or oversized mounting holes.
Replace rim halves (12) or (14) 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 rim half (14) for cracked, broken, rusted, pitted, bent, or loose studs (16).
Inspect studs (16) for damaged or deformed threads. Replace studs (16) if threads are damaged or
if studs (16) are damaged or loose (para. 8-8).
