TFT Monitor Motor Replacement: Monsoon, Tornado, Hurricane, Typhoon, and Tsunami Firefighting Monitors

Replacing the motor on your TFT Monsoon, Tornado, Hurricane, Typhoon, or Tsunami monitors is a straightforward job with the right tools and steps. This guide walks you through a full motor replacement process, including safety precautions and pro tips to make the repair as easy as possible.

Tools & Parts You'll Need

For a successful motor replacement, you’ll need:

  • Y4611-KIT (Motor Kit)
  • 3/16” Allen wrench
  • 7/64” Allen wrench
  • 3mm Allen wrench
  • Side cutters
  • Zip ties
  • Electrical or Scotch tape (optional, but helpful)

Step 1: Power off and Open the Enclosure

  1. Confirm power is off at the monitor. If the master power switch isn’t accessible, use the incoming power pinch plug to disconnect power locally.
  2. Use a 3mm Allen wrench (or Phillips screwdriver for older units) to remove the lid screws.
  3. Gently lift the lid and disconnect the ribbon cable between the front membrane and the communication board by releasing the top and bottom tabs.

Step 2: Locate and Disconnect the Motor

  1. Identify the motor to be replaced (in the video example above we replaced the vertical motor).
  2. Unplug the encoder and power connectors from the vertical motor board.
  3. To gain room, remove the vertical motor board and set it aside.
  4. Use side cutters to clip the old encoder and power wires and remove the zip tie securing the ferrite.

Note: If you’re working on the horizontal motor instead, the same steps apply—just check the wiring layout carefully, as it may differ.

Step 3: Remove the Old Motor

  1. Rotate the monitor to access the motor housing.
  2. Use your 3/16” Allen wrench to remove the motor mounting screws (2–4 depending on the monitor model).
  3. Loosen (don’t remove) the rear cap to give better access and prevent damage during removal.
  4. Next, remove the 4 screws that secure the motor to the enclosure using your 7/64” Allen wrench. These are factory sealed with red Loctite—do not reuse them. New ones are in the kit.

Step 4: Install the New Motor

  1. Carefully remove the old motor, pulling the wires back through the conduit.
  2. Unpack the new pre-crimped motor. Use tape to stiffen the wire ends for easier feeding through the conduit.
  3. Align the red and black wires with the conduit position (just like the original motor).
  4. Rotate and align the new motor until the mounting holes match.
  5. Use the new screws and red Loctite from the kit to secure the motor to the enclosure.

Step 5: Inspect Seals and Reassemble the Housing

  1. Check the cup seal near the motor for tears, debris, or signs of wear. Replace it if needed and apply fresh grease.
  2. Verify the O-ring on the back cap is in place and clean. Reinstall the cap carefully—don’t cross-thread it!
  3. Add blue Loctite to the female threads in the monitor housing (not the bolts), then reinstall and snug down the four mounting bolts. No torque spec—just snug and let the Loctite do the rest.

Step 6: Reconnect and Test

  1. Rewire your power and encoder connectors using the new plugs provided in the kit.
    • Match color-to-color and give each a light tug to ensure they’re seated.
  2. Zip tie the ferrite securely so it doesn’t rattle or shift.
  3. Reinstall the vertical motor board, tuck wires cleanly, and plug everything back in.
  4. Reconnect the ribbon cable, ensuring it’s flush and not angled.
  5. Close the enclosure lid, tightening screws in a crisscross pattern.

Final Step: Power On and Function Check

Restore power to the monitor and test the new motor (vertical or horizontal) using your control station or joystick. If everything rotates as expected, you’re ready to roll.

Pro Tip

  • While you’re inside the enclosure, give all connectors a gentle tug to confirm they’re secure.
  • Replace any damaged seals to prevent corrosion and extend the life of the motor.
