Visual Inspection of the Armature, Continued:
24
E
COMMUTATOR
Look for these obvious defects:
• Burned, charred or cracked insulation.
• Improperly cured varnish.
• Thrown solder.
• Flared armature windings.
• Damaged armature core laminations.
• Worn, burned or glazed commutators.
• Dirty or oily commutators.
• Loose commutator bars.
• Worn armature bearing or shaft.
A dirty or oily commutator should be cleaned and wiped dry. Faults seen during the inspection can aid in
determining the original cause of failure. Slight roughness of the commutator can be polished smooth with
400 or finer sandpaper.
CAUTION
• NEVER USE EMERY CLOTH TO SMOOTH THE COMMUTATOR. PARTICLES OF EMERY ARE
CONDUCTIVE AND MAY SHORT-CIRCUIT THE COMMUTATOR BARS. NEVER USE OIL OR
LUBRICANTS ON THE COMMUTATOR OR BRUSHES.
NOTE
• OIL ON THE COMMUTATOR INDICATES THE POSSIBILITY OF A BAD TRANSAXLE PINION OIL
SEAL.
