Maintenance Schedule
Penetrant Inspection → Overhaul
Per CMM: Per CMM, any wheel requiring penetrant inspection is processed as an overhaul. Owners may elect overhaul at any tire change to extend service life.
Parts Replaced at Tire Change
Every tire change replaces the tire, the main wheel-half preformed packing (O-ring), the valve cap, and the valve core. Specific part numbers and dash sizes vary by wheel and are pulled from the CMM at the time of service.
Always Replaced
Seals & O-Rings
Hardware
During tire change or NDT inspection, additional parts beyond the routine four may require replacement if they fail inspection or meet the rejection criteria defined in the CMM.
Parts Replaced at Overhaul
A full overhaul includes all parts replaced at tire change (listed above), plus the following components inspected and replaced per the CMM:
Seals & O-Rings
Other Parts on the Wheel
These components are part of the wheel assembly but are not replaced during a standard tire change or overhaul. They are only replaced when inspection per the CMM identifies a rejectable condition. APSS stocks or sources these parts on request — contact us for current availability.
