5. Remove end plate.
6. Replace the carbon brushes.
• Observe how the springs roll when the brush is pushed back before taking it apart.
• Remove a brush and spring.
• Install a new brush and spring into the brush holder. Thread the brush wire lead through the brush holder. Position the back
end of the brush in the “cup” of the spring so that the spring will unroll as the brush is pushed back once it is installed.
• Push brush back against the spring and insert a stiff temporary retaining wire (Paper clip) through the access hole in the
end cover. (Remove silicone sealer from the holes) The wire must go through the holes in the brush holder just in front of
the brush to hold the brush back against the spring pressure.
• Install the other three brushes.
