CHECKING CARBON BRUSH (RGX6500, 7500)
If the brush become excessively worn, its
contact pressure with the slip ring changes
and causes a roughened surface on the
slip ring, resulting in irregular generator
performance.
Check the brush every 500 hours or if
generator performance is irregular.
If the brush is 5 mm long or less, replace it
with a new one.
(a) Remove the brush cover.
(b) Disconnect the wire connector and
remove the brush.
(c) Carefully note the brush direction and
relative position with the slip ring when
installing new brush.
