Removing the
Slinger Ring reveals the first motor bearing. This bearing is the one
closest to the water source in the Rainbow vacuum's water pan. The vapor
from this water can corrode the bearings, especially if the vacuum is
stored with water left in the pan (it is best to store all models of Rainbow
vacuums with the pan dry).
Next, remove
the four Phillips screws that secure the two halves of the vacuum together.
It may take a long Phillips screwdriver to reach these screws.
The halves
of the vacuum will then come apart, but cannot be completely separated
because of the wiring. This should be fine, so do not attempt to disconnect
the wires.
Turn the motor
assembly upright, and remove the four screws that secure the white Motor
Shroud to the unit. Then once the white shroud is removed, remove the
Motor Fan by turning it Clockwise. You can see this fan in the image above.
Removing the
Motor Shroud and Motor Fan will reveal the top of the Rainbow's electrical
motor, where the brushes and top bearing are located. You will now need
to remove the contact brushes.
Start by disconecting
the electrical wire that is attached to each of the two brushes with a
spade type fastener. Grasp this spade fastener with a pair of pliers and
carefully pull it free. Wiggle it gently as you pull if it does not want
to come free. Do this for both brushes.
