M2, M2.5 hexagonal spanner; tie wraps; steel rule; brand new Y-axis motor

Note: Please complete the following operations in the power-off state, and keep the removed screws properly to avoid losing them
Disassemble the Y-axis motor
3.Loosen the screws on the coupling, but do not need to remove them.
4.Disconnect the coupling from the Y-axis motor .
5.Unscrew the screws marked in the picture to remove the Y-axis motor.
Mounting Y-axis motor
1. Secure the new motor to the motor base, but without locking.
2. Check that the motor is aligned front to back with the drive shaft. If it is not aligned, loosen the screws marked in the diagram and adjust the position of the motor so that it is aligned front to back with the drive shaft.
3.Check again to see if the motor is aligned with the top and bottom of the drive shaft. If it is not aligned, loosen the screws marked in the diagram and adjust the position of the motor so that it is aligned with the top and bottom of the drive shaft.
4. After confirming that the coupling can travel freely between the motor and the drive shaft, tighten the fixing screws of the motor. 5. Lock the 3 screws on the coupling first, as shown in the picture.

Note: The screws of the 2 couplings need to be facing the same direction.
6. Adjust the orientation of the last screw on the coupling by moving the X-axis so that it is in a position for easy locking. Then use a steel ruler to measure the distance from each side of the X-axis to the end of the Y-axis on the same side, making sure the distance is equal on both sides. As shown in the diagram:
7.After ensuring that the measurements are correct and the distance is the same on both sides, keep the X-axis still and lock the last screw on the coupling.
8. After locking, use the steel ruler to measure the distance from both X-axis to the end of Y-axis on the same side again, whether it is the same; if the distance is not the same, please re-adjust the two couplings.
9. Re-connect the power cable of the Y-axis motor, and use cable ties to regulate the alignment.
10.Reinstall the dust cover to complete the replacement.
