Maintenance Schedule

Eddy Current / NDTEvery tire change

OverhaulThe inspection intervals are calculated as follows: 750 (landings between NDT inspections) divided by 250 (average landings between tire changes) = 3 (number of tire changes between ADDED INSPECTIONS)

Wear Pointsbearings, o-ring grooves, corrosion

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.

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:

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.

Heat shield: replace if cracked, burned, or mechanically damaged.
Bolts and nuts: replace if cracked, corroded, thread-damaged, or failing the back-off torque test.
Bearings (cones and cups): replace if spalled, discolored from heat, pitted, or showing any surface wear.
Wheel halves: replace if cracked, out-of-round beyond CMM limits, or showing seal-groove damage.
Preformed packings and O-rings: replace at every disassembly.
Retaining rings and lockwire: replace whenever removed.
