Look for cracks in the teeth roots.
Document if cracks are present at each segment section using the documentation sheet. The actual number of cracks are not needed.
Demagnetize inspected teeth using tooling (C) .
To demagnetize small parts, energize the probe and pass the parts through the area between the pole ends and withdraw to a distance of about two feet.
On large pieces, place the probe in the same position as inspection. Energize and lift from the work surface to a distance of about two feet.Note: Demagnetization may need repeated more than once to remove the residual field.
