Note: When placing the coil spring and brush back
into position, note the direction the coil spring
faces so that it uncoils properly.
Note: You will need 4 temporary retaining pins, such
as straightened out paperclips. Have them
ready before completing the next steps.
10. While holding the brush (F) and coil spring
(G) together, feed the brush wire through
the brush holder.
11. Insert the brush and coil spring into the
brush holder. The brush wire should be
toward the top, away from the brush cap.
12. Compress the brush all the way in to the
brush holder, and insert the temporary
retaining pin.
• Insert the pin from the opposite side of
the end cap, through the bottom of the
brush holder, in front of the brush, and
up through the top of the brush holder.
• Make sure the pin is inserted in such
a way that it can be removed after the
motor is completely reassembled.
• The purpose of the pin is to hold the
brush retracted while you install the end
cap back onto the motor.
