Field Coil Assembly
1. Replace entire field coil housing assembly if coils, pole shoes or terminals are damaged.
Visual Inspection of Armature
Obvious defects can be seen by examining the armature. If an armature has frayed or charred insulation, bro-
ken wires or thrown solder, it is obvious without testing that it should be replaced. Faults seen during the
visual inspection can aid in diagnosing the original cause of the failure. Items to look for are listed below.
•
Burned, charred, or cracked insulation
•
Improperly cured varnish
•
Thrown solder
•
Flared armature windings
•
Worn, burned, or glazed commutator
•
Loose or raised commutator bars
•
Bruised or damaged armature core laminations
•
Worn armature bearing or shaft
•
Dirty or oily commutator
Commutator Cleaning and Inspection
1. Clean the carbon dust, dirt and oil from the commutator. Visually inspect the commutator for worn,
burned or glazed areas. Check for loose or raised commutator bars. Slight roughness of the commutator
can be polished away with 400 grit (or finer) sandpaper.
See following CAUTION.
