proper secure seating during assembly. Destroy all damaged parts in accordance with the
regulatory supply update.

Inspect wheel assembly (wheel, side ring, and lock ring) completely for any cracked, broken, or
bent surfaces that may indicate excessive heat or impact damage. Check for elongated
mounting holes. Check the lock ring groove for rust, dirt, dents, bends, cracks, burrs, a mashed
groove, and irregular or warped surfaces that may affect lock ring mounting. Clean all rust
and dirt from wheel, side ring, and lock ring surfaces using a wire brush, especially from the
lock ring groove. Check the lock ring ends for burrs or damage that would cause the ends to
touch when assembled. Inspect the two lock ring notches to ensure they are not damaged,
cracked, or torn. Ensure that the outer notch is raised and the liner notch is indented.

Inspect inner tube and flap for cuts, pinch marks, punctures or deterioration. Check valve stem
for damage.
