Vac Motor Carbon Brushes
Replacement
Carbon
Brushes 115V
WARNING: The
green ground wire
must be attached for
safe operation. See
wiring diagram.
NOTE: When replacing carbon vac motor
brushes, loosen wire terminal BEFORE
removing screws on bracket.
If armature commutator is not concentric,
extremely pitted, or grooved, the motor will
need to be replaced or sent to a qualified
service center to restore vac performance.
Important:
These brushes wear
quicker as the length
shortens due to
increased heat.
Spring inside brush
housing will damage
motor if brushes are
allowed to wear away.
Periodically check the length of the carbon
brushes. Replace both carbon brushes when
either is less than 3/8" long.
