Horizontal Thruster Propeller Kit (Left and Right) Replacement Procedures

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

Tools required for this step:

• 7/16 Inch Open End or Socket Wrench

Parts involved in this step:

GTO-006L-KIT~GTO-006R-KIT Horizontal Thruster Propeller Kit (Left and Right)

Quantity	Part Number	Part Description
1	GTO-006L-KIT	Propeller Kit Horizontal 100mm 3 Blade Left (GTO, Deep Blue, Pro 4)
1	GTO-006R-KIT	Propeller Kit Horizontal 100mm 3 Blade Right (GTO, Deep Blue, Pro 4)

Steps

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

1. Orient the horizontal propeller assembly with the open end of the propeller collet toward the horizontal thruster shaft.

2. Press the propeller assembly onto the shaft until it stops. There should be a gap of approximately 1 mm or less between the propeller and the cartridge seal. If there is no gap, the cartridge seal may not be seated - check the cartridge seal to make sure it is fully seated. If the gap is lager than 1 mm, the propeller is not fully seated - You may need to loosen the 7/16 inch acorn nut to allow the collet to open further.

3. Hold the propeller assembly by its hub and tighten the 7/16 inch acorn nut. Do NOT hold the propeller by its blades while tightening the nut, because that could cause a blade to break.

Tip

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

Check to make sure that the propeller turns freely.
