Instructions to Replace the Wind Tunnel Motor on a Hoover

Hoover manufactures a variety of vacuums, including the Wind Tunnel. The motor on the Wind Tunnel can be replaced; a number of vacuum parts distributors carry the motor. To replace the motor, work in a well-lit area and have plenty of room to take the vacuum apart. Keep all the screws and small parts in a designated area so they aren't lost.

Replacing the Motor

Step 1

Unplug the vacuum from the electrical outlet.

Step 2

Turn the vacuum over and lay it flat, with the base of the machine facing up. Unscrew each screw on the base of the vacuum using a Phillips-head screwdriver. Four screws attach the base cover to the vacuum. Remove the base cover by pressing on the clamp on the top of the base cover that holds the cover onto the vacuum.

Step 3

Remove the brush roll by pulling it out of the unit. The belt is attached to the brush roll and the motor pulley, which is part of the vacuum's motor. Remove one end of the belt off of the brush roll and the other end of the belt off of the motor pulley.

Step 4

Turn the vacuum to its upright position. Press the pedal release button to lay the vacuum flat. The top of the base should be facing you. Unscrew the four screws on the top of the electrical cover, using a Phillips-head screwdriver. Remove the two screws on the base of the vacuum that connect the small plates on the rear of the base of the vacuum with a Phillips-head screwdriver.

Step 5

Lift the electrical cover off of the vacuum without disconnecting the wires. When lifting the electrical cover off, lift it up, then turn it to the left to expose the wires and motor. Lift the motor slightly out of the vacuum's base without disconnecting the wires.

Step 6

Place the new motor in front of the vacuum close to the old motor. This will assist you in seeing where each wire should be connected on the new motor.

Step 7

Detach the longest gray wire from the old motor, using needle-nose pliers to remove the wire terminal from the motor's terminal. Attach the same wire onto the new motor. Press the wire terminal into the motor terminal, using your finger. Secure the connection, using needle-nose pliers to push the wire terminal securely into the motor terminal.

Step 8

Locate the two white wires connected to the terminals at the base of the motor. Mark the wire on the left with a black marker to designate which wire goes into the left terminal at the base of the motor. Disconnect the two white wires at the base of the motor, using needle-nose pliers to pull each wire out of the motor terminal.

Step 9

Disconnect the wire attached to the long terminal on the top of the motor, using needle-nose pliers. Remove the old motor from the vacuum.

Step 10

Remove the motor mount from the old motor. The motor mount is a circular piece that wraps around the side of the motor. Pull the piece off, using your hands. Place the motor mount on the new motor.

Step 11

Move the new motor into the vacuum's base with the terminals exposed to connect the remaining wires.

Step 12

Attach the two white wires to the bottom terminal. Connect the wire marked with the marker to the left terminal. Connect the unmarked wire to the right terminal. Press each wire terminal with your finger into the motor's terminal. Use needle-nose pliers to secure the connection.

Step 13

Attach the last wire terminal into the long terminal on the top of the motor, using needle-nose pliers.

Step 14

Place the motor into the vacuum. With the base of the vacuum facing you, the metal rod, referred to as the motor pulley, sits on the right.

Reassembly

Step 15

Place the electrical cover on the vacuum's base without disconnecting the wires.

Step 16

Replace the small plates onto each end of the rear of the vacuum. Screw the two screws onto the plates, using a Phillips-head screwdriver. Screw the four screws back onto the electric cover, using a Phillips-head screwdriver.

Step 17

Turn the vacuum over. Wrap one end of the belt around the motor pulley. Wrap the other end of the belt to around brush roll. Place the brush roll back into the brush roll casing.

Step 18

Attach the base plate to the bottom of the vacuum. Clip the front of the base plate to the clamp on the front of the vacuum. Screw in the four screws to attach the base plate to the vacuum, using a Phillips-head screwdriver.

Step 19

Turn the vacuum over and stand it in its upright position.
