Replace propeller

INFORMATION HUB

This short procedure reuses existing service step pages. Edit the referenced step pages to update this procedure everywhere.

WARNING

Read Safety instructions before starting. Remove the kill switch to prevent accidental motor start. Keep the motor shaft free of rotation during service.

Required tools

• 19mm Socket

Required parts

• 🗑 Safety nut M12 A4 (011020005) — not reusable
• Washer M12 A4 (011030015)
• 🗑 Anode M12 (020010004) — not reusable, sacrificial anode for corrosion protection
• Propeller (047010001)

Disassembly

DT-DIS-001 DISASSEMBLY STEP 1 - Remove anode

Tools:

• 19mm Socket

Removing parts:

• Anode M12 (020010004)

Procedure:

1. Loosen the anode using a 19 mm socket.
2. Remove the anode from the shaft.

DT-DIS-002 DISASSEMBLY STEP 2 - Remove safety nut

Tools:

• 19mm Socket

Removing parts:

• Safety nut M12 A4 (011020005)

Procedure:

1. Loosen the safety nut using a 19 mm socket.
2. Remove the safety nut from the shaft.

DT-DIS-003 DISASSEMBLY STEP 3 - Remove washer and propeller

Tools:

• No tools required.

Removing parts:

• Washer M12 A4 (011030015)
• Propeller (047010001)

Procedure:

1. Remove the washer from the shaft.
2. Remove the propeller by pulling it from the propeller hub.

CAUTION

Do not pull the propeller by only one fin. Pull evenly to avoid damaging the propeller or shaft.

Check

DT-CHK-001 CHECK STEP 1 - Inspect propeller, shear pin and anode

Tools:

• No tools required.

Procedure:

1. Inspect the propeller for bent, cracked or missing blades and check the propeller hub for damage.
2. Inspect the shaft for visual damage, especially in the area of the propeller and washer seat.
3. Inspect the anode for wear. Replace if worn beyond the acceptance criteria.

CAUTION

🗑 The Shear pin (901050006) and Safety nut M12 A4 (011020005) must not be reused. The shear pin is designed to fail under overload and the safety nut loses its locking torque once removed — always install new ones.

TODO

Define the anode wear acceptance criteria (e.g. minimum remaining material) and the propeller damage acceptance criteria (nick/bend limits before replacement is required).

Reassembly

DT-ASM-026 ASSEMBLY STEP 26 - Install propeller and washer

Tools:

• No tools required.

Installing parts:

• Washer M12 A4 (011030015)
• Propeller (047010001)

Procedure:

1. Align the recess in the propeller with the shear pin.
2. Slide the propeller onto the shaft.
3. Slide the washer onto the shaft with the sharp edge of the washer facing down.

CAUTION

Make sure the propeller is correctly seated on the shear pin before continuing.

DT-ASM-027 ASSEMBLY STEP 27 - Install safety nut and anode

Tools:

• 19mm Socket

Installing parts:

• Safety nut M12 A4 (011020005)
• Anode M12 (020010004)

Procedure:

1. Install the safety nut until it bottoms out.
2. Install the anode until it bottoms out.

TODO

This procedure currently has the same steps as Propeller and anode replacement. Confirm whether “Replace propeller” should be a subset that skips anode removal/reinstallation, or whether the two short procedures should be merged.
