• 5/16 Inch Open End Wrench or Nut Driver
• 5/16 Inch Open End Wrench or Nut Driver (Additional)
• Wooden Dowel Rod 3/8" x 12"
• Dental Pick or equivalent
• 3/4 Inch Open End Wrench
• 11/16 Inch Open End Wrench

The following components must be removed:

• Float Block Kit
• Vertical Thruster Propeller Kit
• Vertical Thruster Splitter
• Strain Relief Cable Kit
• Skid Kit
• Horizontal Thruster Propeller Kit (Left and Right)
• Horizontal Thruster Nozzle Kit
• Dome Retaining Rings and Main Hull Rods
• Rear Dome
• Rear Hull Ring Assembly
• Desiccant Pack

See the corresponding sections of this manual for instructions for parts other than the Termination Block and Accessory Port.

Notes:

• The termination block and accessory port connector need to be removed and replaced as a unit. Do NOT attempt to remove or replace only one at a time.

• During this procedure, you will need to keep track of individual wires and their positions within connectors. The wires should have labels to help reinstall them in the correct connector slots. If you notice a wire does not have a label when you remove it, we recommend that you label it and note the corresponding connector slot.

• Some ROVs may have a green/yellow ground wire connected to the termination block. This has been removed in newer models that have the latest pressure sensor. If the ROV has a white housing pressure sensor, the ground wire should not be used. If the ROV has a black housing pressure sensor, the ground wire must be used.

4. Lubricate and install the #017 O-ring over the termination block stud.

5. Place the termination block through the front hole of the termination block plate, with the ROV whip over the accessory port connector. The front hole is closer to the curved edge. The wires should come through the termination block plate on the side with the curved face.

6. Lubricate and install an #114 O-ring over the accessory port connector stud.

7. Lubricate and install an #114 O-ring over the termination block stud.

8. Feed the wires from both connectors through the top holes in the main hull.

9. Pass the wires from the termination block through a termination block spacer and place the spacer over the termination block stud the curved surface of the spacer towards the hull.

10. Apply blue Loctite to the threads of the termination block stud.

11. Pass the wires from the termination block through the termination block 1/2-13, 3/4 inch nut and place the nut over the termination block stud, but do not tighten it all of the way.

12. Pass the wires from the accessory port connector through a termination block spacer and place the spacer over the accessory port connector stud the curved surface of the spacer towards the hull.

13. Apply blue Loctite to the threads of the accessory port connector stud.

14. Pass the wires from the accessory port connector through the accessory port connector washer and place the washer over the accessory port connector stud.

15. Pass the wires from the accessory port connector through the accessory port 7/16-20, 11/16 inch nut and place the nut over the accessory port connector stud, but do not tighten it all of the way.

16. Tighten each nut equally a small amount at a time to 60 inch-pounds (6.8 Nm).

17. Replace the wires into the appropriate slots in the connectors using the tables below.
