  13. Remove the Y-axis motor (5) from the motor bracket (12).
  14. Discard the Y-axis motor (5) in accordance with the local laws and/or regulations.
  15. Do steps 1 to 14 for the adjacent Y-axis motor, if necessary.

Install the New Y-Axis Motors

Make sure that the new Y-axis motor (5) configuration is correct (left or right). To identify the configuration, look at the motor with the cooling block inlet and outlet ports in front of you, and the wires pointing down:
• On the left Y-axis motor (5): The coolant block inlet and outlet ports, found on top, must point to the left.
• On the right Y-axis motor (5): The coolant block inlet and outlet ports, found on top, must point to the right.

Tighten the screw(s) by hand unless a torque value is specified. Do not tighten the screw(s) too much. Failure to do so can cause damage to the machine component(s).

Look at the digital photograph of the Y-axis motor (5) orientation to use as a reference.

  1. Install the new Y-axis motor (5) into the Y-axis motor bracket (12) as follows:
    1. Use a lint-free rag and isopropyl alcohol to clean the Y-axis motor bracket (12), if necessary.
    2. Let the clean surfaces dry for two minutes.
    3. Put the Y-axis motor (5) in position into the Y-axis motor bracket (12). Make sure that the Y-axis motor bracket (12) lower tab is put in position on the outside of the Y-axis motor (5) and that the power cable points up.
    4. Install the four screws (13) through the Y-axis motor (5) holes and into the Y-axis motor bracket (12) holes.

  2. Install the Y-axis belt (8) onto the Y-axis motor pulley (9). Refer to Replace Y-Axis Belts.

    Make sure that the Y-axis belt is installed straight, with no twists, no kinks, and/or no loops. Failure to do so will cause irregular print quality and/or will cause damage to the machine component(s).

  3. Install the coolant tubes onto the Y-axis motor (5) cooling block inlet and outlet ports as follows:

    Be careful when the coolant tube clamps are installed. The coolant tubes are soft and the two coolant tube clamps can be sharp.

    1. Use the identification label(s) to put the coolant tubes in position onto the Y-axis motor (5) cooling block inlet and outlet ports.
    2. Remove and discard the identification label(s).
    3. Put the coolant tube clamps in position onto the Y-axis motor (5) cooling block inlet and outlet ports.
    4. Use the small flathead screwdriver to tighten the screw of the two coolant tube clamps. Do not tighten too much.
  4. Use the identification label(s) to connect the power cable to the Y-axis motor (5).
  5. Remove and discard the identification label(s).
  6. Put the vanity cover (4) in position at the rear of the machine, onto the rear interior panel.
  7. Manually install the six screws (3) through the vanity cover, and into the rear interior panel.
