4. Inspect the armature plate for a consistent wear
pattern. There should be two distinct wear bands
(one band inside the other). If only one band of wear
is present (or if there is wear between the two
bands), inspect the coil area as indicated in Step 5. A
wear band with an interrupted wear mark may
indicate a warped plate, which may cause
intermittent operation. See the following illustrations:
