REPLACEMENT OF BRUSHES AND SPRINGS
1. Brushes that are worn beyond limit line, or are oil-soaked,
should be replaced.
2. When replacing field coil brushes, crush worn brush with pli-
ers, taking care not to damage pigtail.
3. Sand pigtail end with sandpaper to ensure good soldering.
4. Insert pigtail into hole provided in new brush and solder it.
Make sure that pigtail and excess solder do not come out onto
brush surface.
5. When replacing ground brush, slide the brush from brush
holder by prying retaining spring back.
TESTING ARMATURE
TESTING ARMATURE FOR SHORT-CIRCUIT
1. Place armature in a growler.
2. Hold a thin steel blade parallel and just above while rotating
armature slowly in growler. A shorted armature will cause
blade to vibrate and be attracted to the core. Replace shorted
armature.
TESTING ARMATURE FOR GROUNDING
Check the insulation in the space between the segments of the
commutator and the armature and coil core. If there is no conduc-
tivity this is normal.
CHECKING CIRCUIT BREAK BETWEEN ARMATURE AND COIL
Check conductivity between each segment. If there is conductiv-
ity this is normal.
