HT-002-GY-ASSM Horizontal Thruster Cone Assembly

Steps

Note: Both the left (port) and right (starboard) Horizontal Cones must be replaced. Repeat these steps on both sides.

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 rear of the horizontal thruster tube.

2. Orient the horizontal thruster cone assembly at the rear of the horizontal thruster shaft with the large end of the cone facing toward the front of the ROV.

3. Slide the horizontal thruster cone assembly over the thruster motor shaft and being careful not to pinch the O-ring, screw the cone onto the horizontal thruster tube until the base of the cone touches the landing on the thruster tube. Do NOT leave a gap, and do NOT over tighten the thruster cone.

Tip

The horizontal thruster cone has right-handed threads. Turn the thruster cone clockwise, when viewed from the rear of the ROV, in order to tighten it.

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