Curvature in end of motor brush
Use a small screwdriver to gently remove the gold-colored piece and pull the entire brush assembly out of each side
of the motor (see photos below).
Note that the “brush” has a concave end. The brush must be inserted in the same way it was removed. Its concave
shape matches the curvature of the motor housing. You may notice that there are numbers imprinted in the
motor brush itself – the numbers are not important – however, making sure the curve at the end is inserted
properly is very important.
A new motor brush is about ½ inch long when measured from the base to the longer side of the curved end as shown
below. A slight amount of wear is normal. If the brush is less than 3/8-inch long it should be replaced.
