Steps

Note: The following step-by-step instructions apply to one side. Repeat these steps on both sides if you are replacing both Horizontal Drive Trains.

1. Use a new lubricated O-ring, or remove and lubricate the existing O-ring, and install it in the O-ring groove in the open end of the horizontal motor mount.

2. Use a new lubricated O-ring, or remove and lubricate the existing O-ring, and install it over the closed end of the of the horizontal motor mount and slide it up to the stop.

3. Orient the horizontal thruster drive train at the rear of the horizontal thruster tube so that the shaft is to the rear of the ROV and the notch at the front is facing toward the main hull. This notch has to engage with the screw that holds the horizontal thruster tube to the main hull.

4. Connect the like-colored wires from the horizontal motor to the ROV wire harness connector for the motors

.
5. Make sure the wires are inserted into the horizontal thruster tube and will not be pinched by the horizontal thruster drive train when it is inserted.

6. Slide the horizontal thruster drive train into the horizontal thruster tube until the drive train seats inside the tube.

Tip

It may be easier to connect the horizontal motor wires and keep them being pinched by accessing the wires from the front of the horizontal thruster tubes. In order to do this, you need to remove the light domes and LED light modules. See the instructions for removing and replacing the LED light modules for more information.
