Maintenance Schedule

Eddy Current / NDTEvery tire change

OverhaulEvery 6 tire change

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.

Inspection Criteria

General

General overhaul criteria — see the CMM for full specifications and numeric limits:

Drive keys: replace if damaged, corroded, or loose.
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.
