12. Remove the brushes.
A. Using needle nose pliers, unplug the yellow brush wear indicator wire
from the round access hole and the brush wire from the rectangular hole.
B. Press each brush spring in and slowly pull it out. It will be spring
loaded. NOTE: Before you pull out the brushes, take note which way the
brushes are orientated. You will need to replace them in the same
orientation.
C. Pull each brush out from the drive motor.
13. Examine the brushes and commutator.
A. Inspect the commutator by looking through the top brush holder into the
motor. Slowly spin the motor by turning the flywheel. Look for noticeable
damage and for signs of wear such as arcing, pitting, burning, or uneven
wear. Commutator bars that are 'dirty penny' brownish copper are in
great condition. However, some commutator bars may be pitted or
blackened on one edge. Too many of these indicate a worn commutator,
and the motor should be replaced. The commutator may be cleaned with
narrow commutator stone if carbon build-up is present. NOTE: File down
the stone if it won't fit in the brush holder hole. Brush dust can be
loosened from the brush holder area by lightly filing the surfaces.
B. Inspect the brushes for signs of excessive wear or cracks. The motor
brushes must be replaced if one or both is worn to 0.4" (10.2 mm) or
less in length, is broken or chipped, has a broken spring or binds in the
motor. NOTE: For your convenience the decal shown in Figure 13 is
under the motor hood cover.
14. Replace the brushes.
NOTES:If a new brush does not slide in and out easily, the edges or corners of
the brush can be lightly filed down. The motor may make a clicking
noise as new brushes wear in. If you reinstall the original brushes it is
good to install them facing their original position. Reversing the
orientation of the brush can cause a clicking noise during operation
until the brushes wear in.
A. Locate the brush with the two wires and slide it into the motor brush
holder (located nearest the round access hole).
B. Locate the brush with the one wire and slide it into the motor brush
holder on the opposite side.
C. Place a spring clip under each brush and push in and down. The spring
hooks will grasp on to the end of the brush holder.
D. Using needle nose pliers, plug the yellow brush wear indicator wire onto
the fast-on inside the round access hole.
