Overview

Replacing the motor on an Evo2 hook is a straightforward process, but it requires careful attention to detail to ensure everything functions properly afterward. Following the correct procedure is crucial for a successful installation. For visual guidance, you can refer to the supporting videos [here].

Procedure

1. Access the Motor Connections

Begin by removing the front cover of the hook to gain access to the printed circuit board (PCB). Once exposed, carefully desolder the motor cables (Red & Black).

2. Remove the Clutch

Next, disassemble the clutch assembly. This step is essential as it allows you to proceed with the extraction of the motor.

3. Access the Encoder Area

Open the encoder housing to reach the motor. Gently pull the motor cables through the internal routing to free them, taking care not to damage any other wires.

4. Open Rear Covers

Remove the rear covers of the hook. Locate the set screw that secures the motor to the CAM and remove it to facilitate motor removal.

5. Remove the Motor

Extract the motor from the encoder side of the hook. Be cautious during this step to avoid damaging surrounding components.

6. Install the New Motor

Insert the new motor from the encoder side, ensuring it is positioned correctly. Tighten the set screw on the CAM, making sure it aligns properly with the flat/seat on the motor shaft for optimal performance.

7. Route the Cables

Pass the motor cables through the same opening used by the encoder cables. 

8. Cable Positioning

With the hook in the open position, arrange the motor cables to form a loop as demonstrated in the reference videos. Proper cable routing is critical to avoid damage during operation.

9. Electrical Connection

Solder or connect the motor cables back to the PCB, ensuring that each connection is secure and correctly positioned.

10. Reassembly

Finally, reinstall all components in reverse order: start with the encoder, followed by the clutch, and finish with the covers.

Important Notes

Make sure all screws are tightened properly, especially the CAM set screw, to prevent any operational issues. Verify that the cables are not pinched or under tension, as incorrect cable routing can lead to premature failure of the motor.

Final Check

After reassembly, perform a functional test of the hook to confirm that the motor operates correctly. This step is crucial to ensure that your replacement was successful and that the hook is ready for use. If you encounter any issues, double-check your connections and cable routing.
