(2) In motor casing, check coils and leads for damage to insulation and wire. Check for signs of
overheated coils, deteriorated coil end bindings and lashings, and missing or broken coil retainer strips.
(3) Check ball bearings for flat spots or lateral play.
(4) Inspect wavy washer for damage.
e. Component Test
(1) Using the ohmmeter on the multimeter, perform resistance, short, and ground checks on motor casing
coils.
(2) If coils do not test properly, send motor casing to General Support Maintenance for disposition.
(3) If coils are functional and no damage was noted on bearings or fans, send rotor shaft to next higher
level of maintenance for test and repair.
f. Repair and Replace
(1) Replace all gaskets, seals, and O-rings.
(2) Replace all damaged nuts, bolts, screws, washers, shaft keys, Woodruff keys, and wavy washers.
(3) Replace damaged, worn, or unserviceable ball bearing assemblies.
(4) Deburr rotor shaft and remove any spot-weld residue by buffing with fine emery cloth.
(5) Straighten bent or dented cooling fan blades, fan cover, and ventilation louvers.
(6) Replace damaged, unrepairable, or unserviceable motor casing assembly.
(7) Repack serviceable clean bearings with fresh bearing grease before installing.
