Replacement and Reassembly
1. Re-attach the brush clips and the end cap after you make sure that
the brush assembly is properly seated.
Following steps 5 and 6 above, perform the same procedure for
the opposite side.
2. Remove the armature assembly at the top portion of the hopper
loader to properly seat the replacement brushes.
3. Insert a strip of 600-grit sandpaper with the rough side facing the
brush.
4. Release the brush and rotate the commutator back and forth by
hand (See the alternative seating procedure on the facing page) so
that the brush is sanded to match the arc of the commutator.
5. In older motors, the wear of the brushes creates a shallow trough
in the commutator. Sand the brush to conform to the contour.
6. Remove the sandpaper, and repeat steps 5 and 6, as needed until
all brushes are replaced.
7. Reinstall the armature assembly.
