Light Dome Removal Procedures

Time required for this step: Approximately 2 Minutes (4 Minutes for both sides)

Tools required for this step:

• None

Parts involved in this step:

LT-001-4 Light Dome

Quantity	Part Number	Part Description
1	LT-001-4	Light Part Dome Industrial
1	OR-135	O-Ring #135

Steps

Note: The following step-by-step instructions apply to one side. Repeat these steps on both sides if you plan to remove both Light Domes.

1. Unscrew the light dome from the horizontal thruster tube.

2. If you plan to replace the O-ring, remove it by pinching it around the horizontal thruster tube to create a slack section that can be grabbed. Do NOT use a metal tool to remove the O-ring.

Light Dome Replacement Overview

Skill level recommended: Intermediate

Total time required: Approximately 2 Minutes (4 Minutes for both sides)

Tools required:

• O-Ring Lubricator

The following components must be replaced:

• Light Dome

Notes:

• Before installing the light dome, inspect it for scratches or cracks.

• Do NOT use a deeply scratched or cracked dome, because it may fail under pressure.

• This procedure is best done with the ROV nose up, resting on the thruster nozzles. This keeps the LED light modules from falling out while you try to secure the light dome.

Light Dome Replacement Procedures

Time required for this step: Approximately 2 Minutes (4 Minutes for both sides)

Tools required for this step:

• O-Ring Lubricator

Parts involved in this step:

LT-001-4 Light Dome

Quantity	Part Number	Part Description
1	LT-001-4	Light Part Dome Industrial
1	OR-135	O-Ring #135

Steps

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

1. Use a new lubricated O-ring, or remove and lubricate the existing O-ring, and install it in the O-ring groove at the front of the horizontal thruster tube. Make sure the O-ring is seated in the groove.

2. Make sure the LED light module is seated in the thruster tube.

3. Orient the light dome so that the open end is toward the front of the horizontal thruster tube.

4. Screw the light dome onto the horizontal thruster tube until the base of the light dome touches the landing on the horizontal thruster tube. Do NOT leave a gap, and do NOT over tighten the light dome.

Tips

The light dome has right-handed threads. Turn the light dome clockwise, when viewed from the front of the ROV, in order to tighten it.

The light dome diameter is relatively large compared to the thread pitch. Make sure the light dome is on straight before tightening it in order to avoid cross threading the dome onto the horizontal thruster tube.

If you cannot tighten the light dome by hand, you can use a non-slip pad, strap wrench or rubber coated pipe pliers.

Inspect the O-ring under the light dome to make sure it is in contact with the light dome all the way around. The O-ring should look solid black. If you see a lighter colored spot, that could indicate a hair or a piece of dirt and the light dome should be removed and the O-ring and sealing surfaces inspected.
