band and the end cover to expose the brush holders.
Remove the three screws holding each brush holder
in place (Figure 28). Remove the old brushes and
clean the holders so the new brushes can move easily
in their holders. Install the new brushes in the same
manner as the old ones. Always use the correct brush
as listed in the PARTS CATALOG section. Never
substitute a brush which may appear to be the same,
because it may have different characteristics. New
brushes are shaped to fit and seldom need sanding to
seat properly. If some brush sparking occurs after
replacing brushes, run the generating set under a
light load until the brushes wear to a good seat.
Collector rings acquire a glossy brown finish in nor-
mal operation. Do not attempt to maintain a bright
newly machined appearing surface. Ordinary clean-
ing with a dry, lint free cloth is usually sufficient. Do
not use emery or carborundum paper or cloth. Clean
out all carbon dust.
