POSITIONING AND WEAR
(Refer to Figure 9)
When installing the electrical contact brush (3695-00), it is
important that it is properly positioned to provide LIGHT
CONTACT with the bell conductive coating. Excessive
contact pressure from the contact brush will wear away the
conductive coating or the brush tip, causing poor electrical
contact. The small plastic pad at the tip of the brush arm
should lightly contact the black bell coating, not the wire.
The wire should never contact the coating. The tip of the
brush should not extend past the edge of the bell cup or
into the radius at the edge (see Figure 9).

Figure 9-2: Brush Contact Position
The brush should normally have a slight curve to the arm.
The more pressure applied the lesser the curve. The tip of
the brush assembly must be inspected prior to each use for
wear. When one-half (1/2) of the plastic tip is worn away
the brush assembly should be replaced (see Figure 10).
