MOTOR COMPONENT TESTING AND INSPECTION

See General Warning, Section 10, Page 10-1.

ARMATURE INSPECTION AND TESTING

1. Remove the motor from the vehicle. See Motor Removal, Section 16, Page 16-2.
2. Remove the end cap and armature by performing steps 1 through 6 of Motor Disassembly on page 16-4.
Visual Inspection
• 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
• Raised commutator bars
• Worn armature bearing or shaft
A dirty or oily commutator should be cleaned and wiped dry. Abnormalities identified during the inspection can
help determine original cause of failure. Slight roughness of the commutator can be polished smooth with 400
grit or finer sandpaper. See following CAUTION and NOTE.
CAUT ION
• Do not use emery cloth to polish the commutator. Particles of emery are conductive and may
short-circuit the commutator bars. Do not use oil or lubricants on the commutator or brushes.
NOTE: Oil on the commutator may indicate a faulty transaxle input shaft oil seal.
