Tips

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

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