8.5 SERVICING THE LIGHTS

CAUTION! The Light Bulb may be very hot.

1) New bulbs should not be handled with bare fingers. Oils and acids from hands and

fingers can affect the bulb and result in shortened operating life. Protect the bulb with

paper towel or a clean cloth during handling.

2) Open the light housing by carefully unscrewing the light dome. Using a clean rag,

grasp the light bulb and pull it from its socket.

3) Insert the replacement bulb and reassemble the light housing, making sure all O-rings

are properly installed and seated.

The vertical thruster propeller guard is built into the flotation block. The guard should not

be removed from the flotation block. To facilitate cleaning, the flotation block may be

removed by completely loosening the retaining screw. The port and starboard thruster

guards can be removed by unscrewing them from the thruster pods.

1) Remove the thruster guard by unscrewing it from the thruster pod.

2) Following the removal of the appropriate propeller guard, the propeller can be taken off

by first loosening the propeller locking nut (use 7mm wrench), then removing the

propeller by unscrewing it from the propeller shaft. Replacement is accomplished by

reversing this process. Care must be taken to maintain a .75 mm to 1 mm clearance

between the propeller locking nut and the seal spacer to prevent jamming.

Your VideoRay has been equipped with our new, patent-pending cartridge design. This

means that the seals that prevent water from entering the submersible through the motor

shafts can be replaced rapidly and without tools. It also means that you can check for

impending seal failure easily.

There are two "Bal Seals" on the shaft of each of the three thrusters on a VideoRay. Between

these two seals is a oil chamber. The cartridge is constructed of machined acrylic and brass, and

contains the two seals and the oil. To change the cartridges:

1) Remove the nozzle (no tools are needed, just unscrew the nozzle).

2) Use a 7mm wrench to hold the propeller nut and unscrew the propeller.

3) Unscrew the nut and remove the single nylon washer.
